# Polymarket Arbitrage Bot — Design
|
||||||
|
|
||||||
|
## Goal
|
||||||
|
|
||||||
|
Detect and (eventually) capture **NegRisk multi-outcome arbitrage** on Polymarket: cases where the sum of best-ask prices across all outcomes of a categorical event is less than $1, allowing a complete-set buy + redeem for a guaranteed $1 payout.
|
||||||
|
|
||||||
|
Two modes from day one:
|
||||||
|
|
||||||
|
- **Paper** — runs end-to-end against live data, simulates fills, tracks PnL through real on-chain resolutions. No private keys. No capital at risk.
|
||||||
|
- **Live** — signs and submits real orders via `py-clob-client`, hard-capped by basket size, open-basket count, and daily loss.
|
||||||
|
|
||||||
|
A single env var (`ARB_MODE`) flips between them. The opportunity scanner, book maintainer, and risk gates are identical in both modes.
|
||||||
|
|
||||||
|
## The arbitrage
|
||||||
|
|
||||||
|
For a Polymarket negRisk event with outcomes O₁..Oₙ, each outcome trades as its own ERC-1155 token. If outcome Oᵢ wins, holders of Oᵢ receive $1 per share; all other outcomes pay $0. Exactly one outcome wins, so:
|
||||||
|
|
||||||
|
```
|
||||||
|
Σ fair_price(Oᵢ) = $1
|
||||||
|
```
|
||||||
|
|
||||||
|
When `Σ best_ask(Oᵢ) < $1`, buying one share of every outcome costs less than the guaranteed $1 payout. The basket is risk-free (subject to resolution risk — see below) and self-redeems via `NegRiskAdapter.redeemPositions`.
|
||||||
|
|
||||||
|
**Net edge per basket**:
|
||||||
|
```
|
||||||
|
net_edge = $1
|
||||||
|
- Σ vwap_ask(Oᵢ, size)
|
||||||
|
- Σ taker_fee(Oᵢ)
|
||||||
|
- amortized_gas(per_basket)
|
||||||
|
- safety_margin
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Why this stack
|
||||||
|
|
||||||
|
- **Python 3.12 + asyncio** — official `py-clob-client` is Python; mature `web3.py`; fewer moving parts than a JS toolchain.
|
||||||
|
- **FastAPI + HTMX + Jinja2** — single HTML page, no SPA build step, no client-side state.
|
||||||
|
- **SQLite (WAL)** — single-process app, single user; zero ops. Upgrade path to Postgres if multi-process ever happens.
|
||||||
|
- **pydantic v2** — typed contracts at every boundary.
|
||||||
|
- **loguru + structured JSON logs** — searchable post-hoc.
|
||||||
|
- **pytest + pytest-asyncio + respx** — book/math/sim layers fully unit-tested with mocked HTTP.
|
||||||
|
|
||||||
|
## Data model
|
||||||
|
|
||||||
|
| Entity | Key | Notes |
|
||||||
|
|---|---|---|
|
||||||
|
| `Event` | `id` | `negRiskMarketID` for negRisk events; `condition_id` for vanilla. Holds 2..N outcomes. |
|
||||||
|
| `Outcome` | `token_id` | ERC-1155 token id (CTF positionId). One per outcome per event. |
|
||||||
|
| `Book` | `(token_id)` in-mem | Sorted L2; replaced on snapshot, mutated on `price_change`. |
|
||||||
|
| `Opportunity` | `uuid` | Snapshot of legs + sizing + edge math. Persisted whether acted on or not. |
|
||||||
|
| `Basket` | `uuid` | A set of paper or live fills intended to redeem to $1. |
|
||||||
|
| `Fill` | autoinc | Per-leg fill within a basket. |
|
||||||
|
| `Resolution` | `event_id` | Winning outcome token id when oracle resolves. Drives basket redemption + paper PnL. |
|
||||||
|
|
||||||
|
## The hard problems (and how we mitigate)
|
||||||
|
|
||||||
|
### 1. Executable edge ≠ quoted edge
|
||||||
|
The opportunity engine **walks the book on every leg** and computes VWAP for the chosen basket size. The reported `net_edge` and `max_baskets` are clipped by the thinnest leg's depth. Top-of-book is never trusted on its own.
|
||||||
|
|
||||||
|
### 2. Multi-leg fill races (live mode)
|
||||||
|
Strategy: submit all N leg orders in parallel as **FAK (fill-and-kill)**. If any leg partial-fills, immediately try to unwind the over-filled legs at market. Persist every attempt for forensics. The paper executor models this by simulating the same FAK semantics against the observed book.
|
||||||
|
|
||||||
|
### 3. Fees, gas, and the "amortized gas trap"
|
||||||
|
Gas to submit N orders + 1 redeem dominates edge on small baskets. The opportunity engine computes `min_basket_count` such that amortized gas < edge, and refuses to fire below that.
|
||||||
|
|
||||||
|
### 4. Resolution risk (UMA disputes)
|
||||||
|
A "guaranteed" basket can pay $0 if the market resolves "invalid" or gets adversarially redirected. Mitigations:
|
||||||
|
- Skip events within 24h of `end_date` (price action there is dominated by resolution-game theory).
|
||||||
|
- Per-event exposure cap (`MAX_BASKET_USD` × `MAX_OPEN_BASKETS_PER_EVENT=1`).
|
||||||
|
- Persist a denylist of past disputed/invalid markets.
|
||||||
|
|
||||||
|
### 5. Paper-mode realism
|
||||||
|
Naive paper trading assumes you fill at the book at observation time. Real bots get beaten by faster ones. The simulator delays our hypothetical order arrival by `ARB_PAPER_LATENCY_MS` (default 250ms): we only fill against price levels that survived for that latency window, modeling the front-run penalty. This biases paper PnL **down**, which is the safe direction.
|
||||||
|
|
||||||
|
## Lifecycle: paper basket
|
||||||
|
|
||||||
|
1. Engine emits `Opportunity{event_id, legs[], net_edge_bps, max_baskets}`
|
||||||
|
2. Risk gate accepts (under all caps, edge ≥ threshold)
|
||||||
|
3. Paper executor creates `paper_baskets` row with status=`open`
|
||||||
|
4. For each leg: walk the book at `t = detected_at + paper_latency_ms`, compute fills, write `paper_fills` rows
|
||||||
|
5. If any leg lacks depth at the latency-shifted moment → status=`failed`, no PnL impact (this is the "missed it" case)
|
||||||
|
6. Otherwise status=`pending_resolution`, accumulate `total_cost_usd`
|
||||||
|
7. Resolution watcher polls Gamma `/events?id=...` for `closed=true`. On resolve: status=`redeemed`, `realized_pnl_usd = (1 * basket_count) - total_cost_usd` (or `-total_cost_usd` if invalid)
|
||||||
|
|
||||||
|
## Lifecycle: live basket
|
||||||
|
|
||||||
|
Identical to paper through step 2. Then:
|
||||||
|
|
||||||
|
3. Live executor creates `live_orders` rows for each leg with status=`pending`
|
||||||
|
4. Submit all N orders in parallel (FAK) via `py-clob-client`
|
||||||
|
5. Poll fills (or use `user` WS channel)
|
||||||
|
6. If complete-set held → call `NegRiskAdapter.redeemPositions(...)` with current gas estimate; record tx hash
|
||||||
|
7. If partial → submit market unwind orders for the over-filled legs; record net cost
|
||||||
|
8. Resolution watcher mirrors paper for accurate post-mortem PnL on un-redeemed legacy baskets
|
||||||
|
|
||||||
|
## Hard caps (both modes)
|
||||||
|
|
||||||
|
| Cap | Default | Source |
|
||||||
|
|---|---|---|
|
||||||
|
| Min net edge | 50 bps | `ARB_MIN_NET_EDGE_BPS` |
|
||||||
|
| Max basket USD | $50 | `ARB_MAX_BASKET_USD` |
|
||||||
|
| Max open baskets (global) | 3 | `ARB_MAX_OPEN_BASKETS` |
|
||||||
|
| Max open baskets per event | 1 | hard-coded |
|
||||||
|
| Daily loss stop | $100 | `ARB_DAILY_LOSS_STOP_USD` |
|
||||||
|
| Kill switch | `./KILL` file presence | `ARB_KILL_SWITCH_FILE` |
|
||||||
|
| Resolution proximity skip | 24h | hard-coded |
|
||||||
|
|
||||||
|
## Out of scope for v1
|
||||||
|
|
||||||
|
- Cross-platform (Kalshi, Manifold, sportsbooks) — separate funding paths, 2× KYC, no atomic exec.
|
||||||
|
- Vanilla CTF / non-negRisk arbs — the redeem path differs and the sum-to-1 invariant is more fragile.
|
||||||
|
- Maker (passive) strategies — we are takers only.
|
||||||
|
- Options-replication arbs vs Deribit — needs a vol-pricing layer.
|
||||||
|
|
||||||
|
## Phased build
|
||||||
|
|
||||||
|
| Phase | Scope | Capital risk |
|
||||||
|
|---|---|---|
|
||||||
|
| 1 | REST discovery + WS book + opportunity engine + paper executor + dashboard | $0 |
|
||||||
|
| 2 | Live executor (caps minimum), redeem path | ≤ $50/basket × 3 baskets |
|
||||||
|
| 3 | Resolution watcher, daily PnL accounting, denylist | same |
|
||||||
|
| 4 | Scale caps with proven track record; backtest harness | configurable |

# Polymarket Arbitrage Scanner
|
||||||
|
|
||||||
|
A production-grade Python asyncio scanner that detects **NegRisk multi-outcome
|
||||||
|
arbitrage** on Polymarket, simulates fills in paper mode with realistic
|
||||||
|
latency penalties, and can sign + submit live orders through `py-clob-client`
|
||||||
|
behind hard risk gates.

||||||

|
||||||
|
|
||||||
|
## The arbitrage
|
||||||
|
|
||||||
|
Polymarket hosts *categorical* events (e.g. "Who wins the 2028 Election?")
|
||||||
|
where every outcome trades as its own YES token. Because exactly one outcome
|
||||||
|
must win, the fair prices across all outcomes must sum to $1. When the
|
||||||
|
*sum of best-asks* across every outcome drops below $1, buying a complete
|
||||||
|
set is a guaranteed $1 payout — a risk-free arbitrage.
|
||||||
|
|
||||||
|
```
|
||||||
|
Σ best_ask(outcome_i) < $1.00 ⟹ buy one of each, redeem for $1
|
||||||
|
```
|
||||||
|
|
||||||
|
The scanner watches the live CLOB, walks the order book depth to size each
|
||||||
|
leg honestly, subtracts fees and amortised Polygon gas, and emits sized
|
||||||
|
opportunities in real time.
|
||||||
|
|
||||||
|
## Quickstart
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git clone https://github.com/matthewnyc2/arbitrage
|
||||||
|
cd arbitrage
|
||||||
|
python -m venv .venv && source .venv/bin/activate # Windows: .venv\Scripts\activate
|
||||||
|
pip install -e ".[dev]"
|
||||||
|
cp .env.example .env
|
||||||
|
|
||||||
|
arb init # create SQLite schema
|
||||||
|
arb discover # pull active negRisk events from Polymarket
|
||||||
|
arb scan & # start the paper scanner (WS + engine + executor)
|
||||||
|
arb web # dashboard at http://127.0.0.1:8000
|
||||||
|
```
|
||||||
|
|
||||||
|
### Or with Docker
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker compose up
|
||||||
|
# dashboard at http://127.0.0.1:8000

|
|

|
## Modes
|
||||||
|
|
||||||
|
- **`ARB_MODE=paper`** (default) — real data, simulated fills, no keys touched.
|
||||||
|
Paper baskets sit `pending_resolution` until the underlying market closes,
|
||||||
|
then flip to `redeemed` or `invalid` and realized PnL is booked.
|
||||||
|
- **`ARB_MODE=live`** — signs and submits real orders, redeems complete sets
|
||||||
|
via `NegRiskAdapter.redeemPositions`. `LiveExecutor.dry_run=True` by default
|
||||||
|
so orders are logged rather than broadcast until an operator explicitly
|
||||||
|
flips the flag.
|
||||||
|
|
||||||
|
## Safety rails
|
||||||
|
|
||||||
|
| Cap | Env var | Default |
|
||||||
|
|---|---|---|
|
||||||
|
| Minimum net edge (bps) | `ARB_MIN_NET_EDGE_BPS` | 50 |
|
||||||
|
| Max USD per basket | `ARB_MAX_BASKET_USD` | 50 |
|
||||||
|
| Max open baskets (global) | `ARB_MAX_OPEN_BASKETS` | 3 |
|
||||||
|
| Max open baskets per event | hardcoded | 1 |
|
||||||
|
| Daily loss stop (USD) | `ARB_DAILY_LOSS_STOP_USD` | 100 |
|
||||||
|
| Kill switch file | `ARB_KILL_SWITCH_FILE` | `./KILL` |
|
||||||
|
| Paper-mode latency penalty (ms) | `ARB_PAPER_LATENCY_MS` | 250 |
|
||||||
|
|
||||||
|
The dashboard has a red **kill** button that touches the kill-switch file;
|
||||||
|
the executor refuses to open any new baskets while that file exists.
|
||||||
|
|
||||||
|
## Test suite
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pytest # 60 tests, ~5s
|
||||||
|
pytest --cov=arbitrage # with coverage
|
||||||
|
```
|
||||||
|
|
||||||
|
Coverage on the core math layers:
|
||||||

# Security Review: Polymarket Arbitrage Bot
|
||||||
|
|
||||||
|
**Date:** 2026-07-22
|
||||||
|
**Scope:** Full codebase (27 Python files, Docker config, web UI, live executor)
|
||||||
|
**Mode:** Paper mode by default; Live mode requires ARB_MODE=live
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Summary
|
||||||
|
|
||||||
|
| Severity | Count |
|
||||||
|
|----------|-------|
|
||||||
|
| **HIGH** | 3 |
|
||||||
|
| **MEDIUM** | 4 |
|
||||||
|
| **LOW** | 3 |
|
||||||
|
| **INFO** | 3 |
|
||||||
|
|
||||||
|
The codebase follows strong security hygiene in several areas (SecretStr config, parameterized SQL, no hardcoded secrets, proper .gitignore). The critical gaps are around the web UI (no auth), the live executor (dry_run=False in scan mode), and the Docker deployment (exposed dashboard with kill/unkill controls).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## HIGH Severity
|
||||||
|
|
||||||
|
### H1: Live executor runs with `dry_run=False` in `arb scan` — no final confirmation
|
||||||
|
**File:** `arbitrage/cli.py:87-89`
|
||||||
|
|
||||||
|
```python
|
||||||
|
executor = (
|
||||||
|
LiveExecutor(books=books, dry_run=False) # ← no dry_run flag in LiveExecutor!
|
||||||
|
if settings.mode == Mode.LIVE
|
||||||
|
else PaperExecutor(books=books)
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
The `LiveExecutor.__init__` accepts `dry_run` but defaults to `True`. However, the CLI *hardcodes* `dry_run=False` when mode is live. This means `ARB_MODE=live` alone is sufficient to submit real orders. A misconfigured `.env` (or accidental env var bleed from another process) could trigger real trades.
|
||||||
|
|
||||||
|
**Recommendation:** Add an explicit CLI flag (`--confirm-live`) or a one-time confirmation prompt. The current single-env-var guard is acceptable for a CLI tool but should be documented prominently.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### H2: Web UI `/kill` and `/unkill` have zero authentication
|
||||||
|
**File:** `arbitrage/web/app.py:77-88`
|
||||||
|
|
||||||
|
```python
|
||||||
|
@app.post("/kill", response_class=HTMLResponse)
|
||||||
|
async def kill(request: Request) -> HTMLResponse:
|
||||||
|
settings.kill_switch_file.parent.mkdir(parents=True, exist_ok=True)
|
||||||
|
settings.kill_switch_file.touch(exist_ok=True)
|
||||||
|
return await pnl(request)
|
||||||
|
|
||||||
|
@app.post("/unkill", response_class=HTMLResponse)
|
||||||
|
async def unkill(request: Request) -> HTMLResponse:
|
||||||
|
path = settings.kill_switch_file
|
||||||
|
if path.exists():
|
||||||
|
path.unlink()
|
||||||
|
return await pnl(request)
|
||||||
|
```
|
||||||
|
|
||||||
|
In Docker, the web service binds to `0.0.0.0` and exposes port 8000 (`docker-compose.yml:47-51`). Anyone on the network can POST to `/kill` to halt trading, or POST to `/unkill` to bypass a kill switch. No CSRF token, no auth header, no rate limiting.
|
||||||
|
|
||||||
|
**Recommendation:**
|
||||||
|
- Option A: Add a simple API key header check (e.g., `X-Admin-Key`) for `/kill` and `/unkill`
|
||||||
|
- Option B: Bind web to `127.0.0.1` in production and use a reverse proxy with auth
|
||||||
|
- Option C: Add HTTP Basic Auth via uvicorn middleware
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### H3: Docker web dashboard exposed on `0.0.0.0:8000` with no access control
|
||||||
|
**File:** `docker-compose.yml:42-52`
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
web:
|
||||||
|
environment:
|
||||||
|
- ARB_WEB_HOST=0.0.0.0
|
||||||
|
- ARB_WEB_PORT=8000
|
||||||
|
ports:
|
||||||
|
- "8000:8000"
|
||||||
|
```
|
||||||
|
|
||||||
|
Combined with H2, the entire dashboard (including PnL data, basket details, kill/unkill controls) is accessible to any network participant. The dashboard shows event titles, basket counts, realized PnL, and opportunity details — operational intelligence that should not be public.
|
||||||
|
|
||||||
|
**Recommendation:**
|
||||||
|
- Change `ARB_WEB_HOST` to `127.0.0.1` and remove the port mapping, or
|
||||||
|
- Add a reverse proxy (nginx/Caddy) with auth before the dashboard
|
||||||
|
- If remote access is needed, use SSH tunneling or WireGuard
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## MEDIUM Severity
|
||||||
|
|
||||||
|
### M1: `_unwind` sells at `price=0.0` — unprotected market sell
|
||||||
|
**File:** `arbitrage/engine/live_executor.py:261-272`
|
||||||
|
|
||||||
|
```python
|
||||||
|
args = OrderArgs(
|
||||||
|
token_id=fill.token_id,
|
||||||
|
price=0.0, # market — no minimum price protection
|
||||||
|
size=float(fill.size),
|
||||||
|
side="SELL",
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
When unwinding a partial-fill basket, the executor submits SELL orders with `price=0.0`, which Polymarket interprets as a market order. In a fast-moving market, this could execute at an extremely unfavorable price (e.g., if the token price has dropped to near zero during the unwind).
|
||||||
|
|
||||||
|
**Recommendation:** Add a `min_price` parameter (configurable via settings) that sets a floor on the unwind sell price. If the current bid is below the floor, skip the unwind and log it for manual intervention.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### M2: `py-clob-client` dependency is unpinned — supply chain risk
|
||||||
|
**File:** `pyproject.toml:10`
|
||||||
|
|
||||||
|
```toml
|
||||||
|
"py-clob-client>=0.20.0",
|
||||||
|
```
|
||||||
|
|
||||||
|
The docs (`docs/api/order-signing.md:5-7`) explicitly recommend pinning to `0.34.6`. The unpinned `>=` constraint means `pip install` could pull in any version ≥0.20.0, including versions with breaking API changes, security regressions, or supply chain compromises.
|
||||||
|
|
||||||
|
**Recommendation:** Pin to `py-clob-client==0.34.6` and add a CI step to verify the pinned version.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### M3: Kill switch file is trivially bypassed (delete + unkill)
|
||||||
|
**File:** `arbitrage/engine/live_executor.py:57-58`, `arbitrage/web/app.py:83-88`
|
||||||
|
|
||||||
|
```python
|
||||||
|
if limits.kill_switch_file.exists():
|
||||||
|
raise RiskDenied(f"kill switch present: {limits.kill_switch_file}")
|
||||||
|
```
|
||||||
|
|
||||||
|
The kill switch is a simple file existence check (`./KILL` by default). An attacker (or operator) can:
|
||||||
|
1. Delete the file to bypass it (`rm ./KILL`)
|
||||||
|
2. Call `/unkill` to remove it remotely
|
||||||
|
|
||||||
|
There's no write-lock, no integrity check, no audit log of kill switch state changes.
|
||||||
|
|
||||||
|
**Recommendation:** If the kill switch is intended as a hard safety mechanism, use a more robust approach:
|
||||||
|
- A file with write-once semantics (chmod 444 after creation)
|
||||||
|
- An in-memory flag + periodic file check (so deletion alone doesn't resume)
|
||||||
|
- Audit logging of all kill/unkill events
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### M4: TOCTOU race in `risk_gate` basket count check
|
||||||
|
**File:** `arbitrage/engine/live_executor.py:65-95`
|
||||||
|
|
||||||
|
The `risk_gate` function checks the current number of open baskets, then `execute()` proceeds to submit orders. Between the check and the actual submission, another instance/process could open additional baskets, exceeding the configured limits.
|
||||||
|
|
||||||
|
In single-process mode (default), this is low risk. In multi-container deployments (docker-compose has separate `scan` and `discover` services), the risk is higher if multiple `scan` instances run.
|
||||||
|
|
||||||
|
**Recommendation:** Use SQLite's `BEGIN IMMEDIATE` or a row-level advisory lock around the risk check + order submission. For production multi-instance deployments, use a Redis-based distributed lock.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## LOW Severity
|
||||||
|
|
||||||
|
### L1: No rate limiting on web fragment endpoints
|
||||||
|
**File:** `arbitrage/web/app.py:43-74`
|
||||||
|
|
||||||
|
The `/fragments/*` endpoints are polled every 2-3 seconds via HTMX. There's no rate limiting or DoS protection. An attacker could consume excessive DB connections or CPU by spamming requests.
|
||||||
|
|
||||||
|
**Recommendation:** Add a simple request counter or `slowapi` middleware. Low priority since the web is intended for local use.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### L2: JSHTMX loads from unpinned CDN
|
||||||
|
**File:** `arbitrage/web/templates/index.html:6`
|
||||||
|
|
||||||
|
```html
|
||||||
|
<script src="https://unpkg.com/htmx.org@2.0.3"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
While unpinned (`@2.0.3` is specified), unpkg doesn't pin the sub-version. If `2.0.3` is yanked or compromised, a different version could be served. For a self-hosted dashboard this is low risk, but worth noting.
|
||||||
|
|
||||||
|
**Recommendation:** Pin the full version hash or self-host the HTMX bundle.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### L3: `raw_json` in DB could contain sensitive event metadata
|
||||||
|
**File:** `arbitrage/clients/polymarket_rest.py:204`
|
||||||
|
|
||||||
|
```python
|
||||||
|
raw_json = json.dumps(raw_by_id.get(ev.id))
|
||||||
|
```
|
||||||
|
|
||||||
|
Full raw Gamma event JSON is persisted to the SQLite `raw_json` column. While this is Polymarket's public data, it's worth considering if any sensitive operational fields leak in (e.g., internal IDs, timestamps that reveal monitoring cadence).
|
||||||
|
|
||||||
|
**Recommendation:** Review the Gamma API response shape and selectively store only needed fields. Or accept this as low-risk since the data is public.

## INFO (Good Practices Observed)
|
||||||
|
|
||||||
|
### I1: Secrets management via `SecretStr` ✅
|
||||||
|
`config.py:32-36` uses `pydantic.SecretStr` for all sensitive fields (private key, API key, secret, passphrase). `SecretStr.get_secret_value()` is the only way to access plaintext, which prevents accidental logging.
|
||||||
|
|
||||||
|
### I2: Parameterized SQL everywhere ✅
|
||||||
|
All database queries use `?` placeholders with parameter tuples. No string interpolation, no f-strings in SQL. Zero SQL injection risk.
|
||||||
|
|
||||||
|
### I3: `.env` properly excluded ✅
|
||||||
|
`.env` is in `.gitignore` (line 6), `.env.example` contains only defaults. No secrets in source.
|
||||||
|
|
||||||
|
### I4: Logging configured to avoid backtraces ✅
|
||||||
|
`logging_setup.py:13-14` sets `backtrace=False, diagnose=False` — prevents stack traces from leaking sensitive local variable values in log files.
|
||||||
|
|
||||||
|
### I5: Mode guard on LiveExecutor ✅
|
||||||
|
`live_executor.py:117-119` raises `RuntimeError` if instantiated when `ARB_MODE != live`. This is a good belt-and-suspenders check.
|
||||||
|
|
||||||
|
### I6: `dry_run` defaults to `True` in LiveExecutor ✅
|
||||||
|
`live_executor.py:116`: `dry_run: bool = True` — the constructor is safe by default. Only the CLI overrides it.
|
||||||
|
|
||||||

## Risk Matrix (Live Mode Only)
|
||||||
|
|
||||||
|
| Threat | Impact | Likelihood | Mitigation Status |
|
||||||
|
|--------|--------|------------|-------------------|
|
||||||
|
| Accidental live trade from misconfigured .env | Financial loss | Medium | Partial (mode check) |
|
||||||
|
| Remote kill/unkill via web UI | Operational | High | None |
|
||||||
|
| Unprotected market sell during unwind | Financial loss | Low | None |
|
||||||
|
| Supply chain via unpinned py-clob-client | Unknown | Low | None |
|
||||||
|
| TOCTOU race on basket limits | Over-exposure | Low-Medium | None |
|
||||||
|
| XSS in dashboard | Data leak | Very Low | Jinja2 autoescape |
|
||||||
|
| SQL injection | Data compromise | None | Parameterized queries |
|
||||||
|

|
||||||
|
|
||||||
|
## Priority Recommendations
|
||||||
|
|
||||||
|
1. **🔴 Add auth to web `/kill` and `/unkill`** — or remove the web server from production Docker
|
||||||
|
2. **🔴 Add `--confirm-live` flag to `arb scan`** — prevent accidental live execution
|
||||||
|
3. **🟡 Pin `py-clob-client==0.34.6`** in `pyproject.toml`
|
||||||
|
4. **🟡 Add min-price protection to `_unwind` SELL orders**
|
||||||
|
5. **🟡 Change Docker web to `127.0.0.1`** or add reverse proxy auth
|
||||||
|
6. **🟢 Add rate limiting to web endpoints**
|
||||||
|
7. **🟢 Self-host or pin HTMX script hash**

<h2>2. What it can do</h2>
|
||||||
|
|
||||||
|
<h3>The trade it looks for</h3>
|
||||||
|
<p>
|
||||||
|
Polymarket hosts "categorical" markets — say, "Who wins the 2028 US Election?"
|
||||||
|
with one YES token per candidate. Because exactly one candidate wins, the
|
||||||
|
fair prices of every YES token must sum to exactly $1. When someone in the
|
||||||
|
order book is selling those YES tokens cheaply enough that the <em>sum of best
|
||||||
|
offers adds up to less than $1</em>, you can buy one of each and hold a
|
||||||
|
guaranteed $1 per basket. The gap between that sum and $1 is the profit.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h3>What the bot does about it</h3>
|
||||||
|
<ol>
|
||||||
|
<li><strong>Discovers</strong> the categorical events on Polymarket.</li>
|
||||||
|
<li><strong>Subscribes</strong> to their live order books over a WebSocket.</li>
|
||||||
|
<li><strong>Watches</strong> every book update and re-runs the math.</li>
|
||||||
|
<li><strong>Sizes</strong> the trade honestly — it walks the depth on each
|
||||||
|
leg, doesn't trust the top-of-book quote, and subtracts fees and the
|
||||||
|
Polygon gas cost amortised across the basket.</li>
|
||||||
|
<li><strong>Logs</strong> every qualifying opportunity to SQLite.</li>
|
||||||
|
<li><strong>In paper mode:</strong> simulates the fills with a realistic
|
||||||
|
latency penalty (250 ms by default, modelling "faster bots got there
|
||||||
|
first"), records what it would have paid, and marks realised PnL when
|
||||||
|
the event resolves.</li>
|
||||||
|
<li><strong>In live mode:</strong> submits FAK (fill-and-kill) orders on
|
||||||
|
every leg in parallel, unwinds anything that partial-fills, and defers
|
||||||
|
the on-chain redeem to a watcher you still have to build or run
|
||||||
|
manually.</li>
|
||||||
|
<li><strong>Respects hard caps</strong> on basket size, total open baskets,
|
||||||
|
daily loss, and a kill-switch file. It refuses to trade if any of those
|
||||||
|
trip.</li>
|
||||||
|
<li><strong>Shows you what it's doing</strong> on a dashboard that refreshes
|
||||||
|
itself every few seconds.</li>
|
||||||
|
</ol>

<h2>3. How to use it</h2>
|
||||||
|
|
||||||
|
<h3>First-time setup (paper mode, no keys)</h3>
|
||||||
|
<pre>cd C:\Users\matt\Dropbox\projects\arbitrage
|
||||||
|
.venv\Scripts\activate
|
||||||
|
pip install -e .
|
||||||
|
copy .env.example .env # defaults are fine for paper mode
|
||||||
|
arb init # create the SQLite database</pre>
|
||||||
|
|
||||||
|
<h3>Run it</h3>
|
||||||
|
<p>
|
||||||
|
Open three terminals (or use a background process per step). In paper mode
|
||||||
|
nothing you do here touches real money.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<pre># Terminal 1 — keep the event list fresh
|
||||||
|
arb discover --loop
|
||||||
|
|
||||||
|
# Terminal 2 — start the scanner (WS + engine + paper executor)
|
||||||
|
arb scan
|
||||||
|
|
||||||
|
# Terminal 3 — dashboard
|
||||||
|
arb web
|
||||||
|
# open http://127.0.0.1:8000</pre>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Walk away for a few hours. Opportunities will log to the dashboard and into
|
||||||
|
SQLite. Paper baskets will move from <em>pending_resolution</em> →
|
||||||
|
<em>redeemed</em> (or <em>invalid</em>) as the underlying Polymarket events
|
||||||
|
close out. At that point your paper realised-PnL column tells you whether
|
||||||
|
the strategy would have been worth running.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h3>Kill switch</h3>
|
||||||
|
<p>
|
||||||
|
Click the red <strong>kill</strong> button on the dashboard, or
|
||||||
|
<code>touch KILL</code> in the project folder. The executor refuses to open
|
||||||
|
any new baskets while that file exists.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h3>Manually resolving an event (until the auto-watcher exists)</h3>
|
||||||
|
<pre>arb resolve <negRiskMarketID> --winner <winning_token_id>
|
||||||
|
arb resolve <negRiskMarketID> --winner invalid # UMA voided it</pre>
|
||||||
|
|
||||||
|
<h3>Going live (not recommended yet — see §4)</h3>
|
||||||
|
<p>Edit <code>.env</code>:</p>
|
||||||
|
<pre>ARB_MODE=live
|
||||||
|
ARB_PRIVATE_KEY=0x... # dedicated wallet, small balance
|
||||||
|
ARB_FUNDER_ADDRESS=0x... # same as wallet for EOA
|
||||||
|
ARB_MAX_BASKET_USD=25 # keep it tiny for first real runs
|
||||||
|
ARB_MAX_OPEN_BASKETS=1</pre>
|
||||||
|
<p>
|
||||||
|
Even after you do this, the live executor defaults to <code>dry_run=True</code>
|
||||||
|
in code — meaning it still logs what it <em>would</em> have signed rather than
|
||||||
|
broadcasting. To actually broadcast orders you have to change the
|
||||||
|
<code>dry_run</code> flag in <code>arbitrage/cli.py</code>. This is an
|
||||||
|
intentional safety belt.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>4. Will it work in the real world?</h2>
|
||||||
|
|
||||||
|
<p><strong>Honest answer: the code will run. Whether it will <em>make money</em>
|
||||||
|
is an open empirical question — and the default expectation should be "no,
|
||||||
|
not yet."</strong></p>
|
||||||
|
|
||||||
|
<h3>Why that's the default answer</h3>
|
||||||
|
<ul>
|
||||||
|
<li><strong>This arb is old news.</strong> NegRisk categorical mispricings
|
||||||
|
on Polymarket are well known to every market-making bot on the
|
||||||
|
platform. The big ones are usually closed out in milliseconds. What
|
||||||
|
remains is the long tail of briefly-stale quotes on thin markets near
|
||||||
|
event close.</li>
|
||||||
|
<li><strong>We are slow compared to the pros.</strong> Our scanner is a
|
||||||
|
Python process in the US on residential internet, reading a public
|
||||||
|
WebSocket. A serious HFT-style competitor runs closer to the CLOB and
|
||||||
|
uses pre-signed order batches. The 250 ms paper-mode latency
|
||||||
|
penalty is meant to approximate being behind them, and it is probably
|
||||||
|
optimistic.</li>
|
||||||
|
<li><strong>Depth is shallow at the edge.</strong> When the math does
|
||||||
|
cross, there are usually only a few hundred dollars of lift available
|
||||||
|
before the sum climbs back above $1. Fee-wise the trade still works;
|
||||||
|
capital efficiency-wise it's unimpressive.</li>
|
||||||
|
<li><strong>Resolution risk is real.</strong> Polymarket events settle via
|
||||||
|
UMA's optimistic oracle. A disputed market can resolve differently
|
||||||
|
than you expected or even "invalid" with zero payout. The strategy is
|
||||||
|
not actually risk-free — it is risk-<em>small</em> most of the time
|
||||||
|
and occasionally very expensive. The denylist and proximity-to-close
|
||||||
|
skip exist for this reason.</li>
|
||||||
|
<li><strong>Gas is hardcoded.</strong> We assume $0.10 of Polygon gas per
|
||||||
|
basket. During a gas spike that assumption breaks, and the bot will
|
||||||
|
happily enter trades that are actually negative-EV after real gas.
|
||||||
|
Wiring a gas oracle is on the Phase 3 list.</li>
|
||||||
|
<li><strong>We haven't proved the WebSocket works.</strong> The parser
|
||||||
|
matches Polymarket's documented format and the test suite exercises
|
||||||
|
it, but there is no substitute for a connection test against the real
|
||||||
|
server. That is the first thing to do when you flip it on.</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<h3>What a realistic path forward looks like</h3>
|
||||||
|
<ol>
|
||||||
|
<li><strong>Paper-mode burn-in, one week.</strong> Run it continuously,
|
||||||
|
watch the dashboard fill up, let events resolve. Total realised paper
|
||||||
|
PnL at the end of that week is your headline number. If it's net
|
||||||
|
negative after the latency penalty, don't even think about live mode.</li>
|
||||||
|
<li><strong>Investigate the misses.</strong> Every time the paper executor
|
||||||
|
writes a <em>failed</em> basket (because depth vanished during the
|
||||||
|
latency window) that's a trade a faster bot beat us to. Ratio of
|
||||||
|
<em>failed</em> to <em>redeemed</em> is a proxy for how competitive the
|
||||||
|
environment is.</li>
|
||||||
|
<li><strong>Tune or give up.</strong> If paper PnL is marginal, try a
|
||||||
|
tighter minimum edge, larger basket sizes, only near-close events, or
|
||||||
|
only low-volume events where the HFT bots don't bother. If it's still
|
||||||
|
marginal, this strategy on this venue may simply be claimed.</li>
|
||||||
|
<li><strong>Only then, flip live with a tiny cap.</strong> $25 basket, one
|
||||||
|
open at a time, one event. Expect slippage between paper and live PnL
|
||||||
|
of at least 20–50% because the simulator can't model every
|
||||||
|
micro-structural detail.</li>
|
||||||
|
</ol>
|
||||||
|
|
||||||
|
<h3>What would make me optimistic</h3>
|
||||||
|
<p>
|
||||||
|
Paper realised PnL of roughly <strong>+0.5% per basket, averaged across
|
||||||
|
≥50 baskets</strong>, with failure rate under a third. Below that, there
|
||||||
|
isn't enough margin to survive the gap between simulated and live execution.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Above that, you still have to check that the opportunities it claims are
|
||||||
|
scattered across many events (rather than concentrated in one lucky market
|
||||||
|
that resolved favourably), and that the PnL is stable week-over-week rather
|
||||||
|
than driven by one big win. Arbitrage should look boring and small on the
|
||||||
|
balance curve — a straight line tilted gently up. If paper mode produces a
|
||||||
|
hockey stick, something is wrong with the simulation and it will not
|
||||||
|
replicate live.

# Polymarket NegRisk Reference (Polygon mainnet)
|
||||||
|
|
||||||
|
Single-page reference for arbitraging categorical Polymarket events where
|
||||||
|
`Σ(best-ask of every outcome) < $1`. Covers the contracts, ABI, lifecycle, Gamma
|
||||||
|
API detection, ID derivation, a runnable web3.py snippet, and gotchas.
|
||||||
|
|
||||||
|
All sources cited inline. Last verified: April 2026.
|
||||||

|
||||||
|
|
||||||
|
## 1. Concept
|
||||||
|
|
||||||
|
Vanilla Polymarket markets use Gnosis's **Conditional Token Framework (CTF)**:
|
||||||
|
each binary market mints a YES and a NO ERC-1155 token, fully collateralized 1:1
|
||||||
|
by USDC.e. Splitting 1 USDC.e gives `1 YES + 1 NO`; merging the pair returns
|
||||||
|
1 USDC.e; after resolution the winning side redeems for 1 USDC.e each.
|
||||||
|
|
||||||
|
A **categorical event** ("Who wins the 2028 US Election?") is modeled as N
|
||||||
|
independent binary markets — one per candidate. Without negRisk these markets
|
||||||
|
are unconnected, which means a holder of `NO` on every candidate is locked up
|
||||||
|
even though, by construction, exactly one of them must resolve YES. NegRisk
|
||||||
|
fixes this: the **NegRiskAdapter** wraps the underlying CTF and adds a
|
||||||
|
`convertPositions` operation: 1 NO share in market *i* of an event can be
|
||||||
|
atomically converted into 1 YES share in **every other** market of that event.
|
||||||
|
That makes a complete set of YES tokens (one per outcome) economically
|
||||||
|
equivalent to $1 USDC.e and lets capital be freed early instead of waiting for
|
||||||
|
oracle resolution. This is the property the arb strategy exploits — when the
|
||||||
|
best-ask sum of every outcome's YES token is below $1, you can buy a complete
|
||||||
|
set, redeem (or convert+redeem), and lock in the spread.

## 3. Key ABI signatures
|
||||||
|
|
||||||
|
The NegRiskAdapter exposes both vanilla CTF-shaped overloads (so it can act as
|
||||||
|
a drop-in `IConditionalTokens` proxy) and negRisk-specific entrypoints. Source:
|
||||||
|
[`NegRiskAdapter.sol`](https://github.com/Polymarket/neg-risk-ctf-adapter/blob/main/src/NegRiskAdapter.sol),
|
||||||
|
[`docs/NegRiskAdapter.md`](https://github.com/Polymarket/neg-risk-ctf-adapter/blob/main/docs/NegRiskAdapter.md).
|
||||||
|
|
||||||
|
### 3.1 Position management (call these on the NegRiskAdapter)
|
||||||
|
|
||||||
|
```solidity
|
||||||
|
// Mint a complete set: deposits `_amount` USDC.e, mints `_amount` of each YES & NO.
|
||||||
|
function splitPosition(bytes32 _conditionId, uint256 _amount) external;
|
||||||
|
|
||||||
|
// Burn a complete set (YES + NO of every outcome of the condition) for USDC.e.
|
||||||
|
function mergePositions(bytes32 _conditionId, uint256 _amount) external;
|
||||||
|
|
||||||
|
// After UMA resolution, redeem held outcome tokens for USDC.e payout.
|
||||||
|
// _amounts[i] is the amount of outcome-i token to burn.
|
||||||
|
function redeemPositions(bytes32 _conditionId, uint256[] calldata _amounts) external;
|
||||||
|
|
||||||
|
// negRisk-specific: convert NO shares in markets selected by `_indexSet`
|
||||||
|
// (a bitmask over the marketId's questions) into YES shares of the rest + collateral.
|
||||||
|
function convertPositions(bytes32 _marketId, uint256 _indexSet, uint256 _amount) external;
|
||||||
|
```
|
||||||
|
|
||||||
|
There are also legacy 5-arg overloads kept for `IConditionalTokens` API parity
|
||||||
|
(unused by clients in practice):
|
||||||
|
|
||||||
|
```solidity
|
||||||
|
function splitPosition(address _collateralToken, bytes32, bytes32 _conditionId,
|
||||||
|
uint256[] calldata, uint256 _amount) external;
|
||||||
|
function mergePositions(address _collateralToken, bytes32, bytes32 _conditionId,
|
||||||
|
uint256[] calldata, uint256 _amount) external;
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.2 ID lookups (view)
|
||||||
|
|
||||||
|
```solidity
|
||||||
|
function getConditionId(bytes32 _questionId) external view returns (bytes32);
|
||||||
|
function getPositionId(bytes32 _questionId, bool _outcome) external view returns (uint256);
|
||||||
|
function balanceOf(address _owner, uint256 _id) external view returns (uint256);
|
||||||
|
function balanceOfBatch(address[] memory _owners, uint256[] memory _ids)
|
||||||
|
external view returns (uint256[] memory);
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.3 Admin / oracle (you will not call these, but useful for tracing)
|
||||||
|
|
||||||
|
```solidity
|
||||||
|
function prepareMarket(uint256 _feeBips, bytes calldata _metadata) external returns (bytes32);
|
||||||
|
function prepareQuestion(bytes32 _marketId, bytes calldata _metadata) external returns (bytes32);
|
||||||
|
function reportOutcome(bytes32 _questionId, bool _outcome) external; // onlyOperator
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.4 Required ERC-20 / ERC-1155 approvals
|
||||||
|
|
||||||
|
Before any of the above, set:
|
||||||
|
|
||||||
|
```solidity
|
||||||
|
// USDC.e:
|
||||||
|
IERC20(USDC_E).approve(NegRiskAdapter, type(uint256).max);
|
||||||
|
|
||||||
|
// ERC-1155 outcome tokens (for merge / redeem / convert):
|
||||||
|
IConditionalTokens(CTF).setApprovalForAll(NegRiskAdapter, true);
|
||||||
|
```
|
||||||
|
|
||||||
|

## 4. End-to-end arb lifecycle
|
||||||
|
|
||||||
|
For a categorical event with N outcomes where `Σ best_ask_i < 1`:
|
||||||
|
|
||||||
|
1. **Approvals (one-time per wallet)**
|
||||||
|
- `USDC.e.approve(NegRiskAdapter, 2^256-1)`
|
||||||
|
- `ConditionalTokens.setApprovalForAll(NegRiskAdapter, true)`
|
||||||
|
- Approvals required for the **NegRiskCtfExchange** (`0xC5d5...80a`) for
|
||||||
|
trading: `USDC.e.approve(exchange, ...)` and
|
||||||
|
`ConditionalTokens.setApprovalForAll(exchange, true)`.
|
||||||
|
|
||||||
|
2. **Buy a complete set via the Exchange**
|
||||||
|
- Use the CLOB (`py-clob-client`, set `neg_risk=True` on the order options)
|
||||||
|
to lift the best ask of each of the N outcome tokens for `size` shares.
|
||||||
|
Total USDC.e spent ≈ `size * Σ best_ask_i`, which is < `size * $1`.
|
||||||
|
- Equivalent: hit each `clobTokenIds[YES]` from the Gamma `markets[]` array.
|
||||||
|
|
||||||
|
3. **Redeem on resolution OR free capital early**
|
||||||
|
- **Patient path**: wait for UMA to resolve the event and call
|
||||||
|
`NegRiskAdapter.redeemPositions(conditionId_winner, [size, 0])` on the
|
||||||
|
winning binary market. Payout = `size * 1 USDC.e`. Profit
|
||||||
|
= `size * (1 − Σ best_ask_i)` minus gas and fees.
|
||||||
|
- **Capital-recycling path** (the negRisk superpower): once you hold one
|
||||||
|
YES of every outcome of the event, that bundle is economically `$1` per
|
||||||
|
unit. Rather than redeem on each binary, you can `convertPositions` to
|
||||||
|
consolidate, or simply burn the bundle: per the adapter, holding the
|
||||||
|
full YES set is interchangeable with USDC.e, so a `mergePositions` on
|
||||||
|
each conditionId (each binary has its own NO if you also hold it, or
|
||||||
|
use `convert`) returns USDC.e instantly without waiting for the oracle.
|
||||||
|
Practically: most arb bots redeem after resolution because acquiring a
|
||||||
|
full NO+YES pair on every binary defeats the point — you bought only the
|
||||||
|
YES legs for the discount.
|
||||||
|
|
||||||
|
4. **USDC.e arrives in your wallet.** Fees: NegRisk markets pay a small
|
||||||
|
protocol fee on conversion (defined by `_feeBips` at `prepareMarket`
|
||||||
|
time, paid to the Vault); redeem itself has no Polymarket fee.

## 5. Detecting negRisk markets via the Gamma API
|
||||||
|
|
||||||
|
Endpoint: `https://gamma-api.polymarket.com/events?...`
|
||||||
|
|
||||||
|
The two flags that matter on each `event` JSON object:
|
||||||
|
|
||||||
|
| JSON field | Type | Meaning |
|
||||||
|
|---|---|---|
|
||||||
|
| `negRisk` | bool | `true` → categorical event; outcomes are tied via the NegRiskAdapter. |
|
||||||
|
| `negRiskMarketID` | hex string (`bytes32`) | The shared `marketId` that links every binary in this event. Same value also appears on each child `markets[i].negRiskMarketID`. |
|
||||||
|
| `enableNegRisk` | bool | Set on a market when it can be added later as a new outcome (placeholder-capable). |
|
||||||
|
| `negRiskAugmented` | bool | Indicates the event has been augmented with such placeholder markets. |
|
||||||
|
|
||||||
|
The relevant fields inside each `markets[i]` element:
|
||||||
|
|
||||||
|
| JSON field | Use |
|
||||||
|
|---|---|
|
||||||
|
| `conditionId` (`bytes32`) | Pass to `redeemPositions` / `splitPosition`. |
|
||||||
|
| `questionID` (`bytes32`) | Source of `conditionId` via `getConditionId(questionID)`. |
|
||||||
|
| `clobTokenIds` | `[YES_tokenId, NO_tokenId]` as decimal strings. These are the ERC-1155 ids you reference to the CLOB order book. |
|
||||||
|
| `outcomePrices` | `["yes", "no"]` last-trade probabilities. Use `book` REST/WS for live best ask. |
|
||||||
|
|
||||||
|
Sample (trimmed) — `2026 FIFA World Cup Winner` event:
|
||||||
|
|
||||||
|
```json

Sample query to surface candidates:
|
||||||
|
|
||||||
|
```python
|
||||||
|
import requests
|
||||||
|
events = requests.get(

|
||||||
|
"ascending": "false"},
|
||||||
|
timeout=15,
|
||||||
|
).json()
|
||||||
|
neg_risk_events = [e for e in events if e.get("negRisk")]
|
||||||
|
for e in neg_risk_events:
|
||||||
|
yes_asks = [float(m["outcomePrices"][0]) for m in e["markets"]]
|
||||||
|
if sum(yes_asks) < 0.99: # candidate; verify against live book
|
||||||
|
print(e["title"], sum(yes_asks))
|

## 6. How `tokenId` and `conditionId` are derived
|
||||||
|
|
||||||
|
NegRisk markets reuse the underlying CTF derivation rules but plug a
|
||||||
|
**WrappedCollateral** ERC-20 in place of raw USDC.e. That changes which
|
||||||
|
collateral address goes into `positionId` — the one number that frequently
|
||||||
|
trips up new integrators.
|
||||||
|
|
||||||
|
### 6.1 Vanilla CTF (used by non-negRisk binary markets)
|
||||||
|
|
||||||
|
```text
|
||||||
|
conditionId = keccak256( oracle ‖ questionId ‖ outcomeSlotCount )
|
||||||
|
collectionId = EC point-add of (parentCollectionId, hashToCurve(conditionId ‖ indexSet))
|
||||||
|
positionId = uint256( keccak256( collateralToken ‖ collectionId ) )
|
||||||
|
```
|
||||||
|
|
||||||
|
For a vanilla binary market: `oracle = UmaCtfAdapter`, `outcomeSlotCount = 2`,
|
||||||
|
`collateralToken = USDC.e`, `indexSet = 1` for YES and `2` for NO.
|
||||||
|
(Source: [CTHelpers.sol](https://raw.githubusercontent.com/Polymarket/neg-risk-ctf-adapter/main/src/libraries/CTHelpers.sol))
|
||||||
|
|
||||||
|
### 6.2 NegRisk markets (the difference)
|
||||||
|
|
||||||
|
For each outcome of a categorical event, NegRisk creates an independent
|
||||||
|
binary CTF condition, **but** with two changes:
|
||||||
|
|
||||||
|
1. The CTF `oracle` field is set to the **NegRiskAdapter address**
|
||||||
|
(`0xd91E…5296`) — not UmaCtfAdapter. The NegRiskAdapter is itself the
|
||||||
|
thing that calls `reportPayouts` upstream.
|
||||||
|
2. The `collateralToken` baked into `positionId` is the
|
||||||
|
**WrappedCollateral** ERC-20 (deployed by the adapter), not USDC.e. The
|
||||||
|
adapter holds USDC.e and mints/burns wrapper tokens 1:1 against it.
|
||||||
|
|
||||||
|
Practically:
|
||||||
|
|
||||||
|
- `marketId` (the negRisk-level grouping) =
|
||||||
|
`keccak256(operator ‖ feeBips ‖ metadata ‖ nonce)` — assigned at
|
||||||
|
`prepareMarket` time and is what `negRiskMarketID` in Gamma exposes.
|
||||||
|
- `questionId` for the i-th binary in the event =
|
||||||
|
`keccak256(marketId ‖ i)` (the index byte is the `_questionIndex`),
|
||||||
|
which keeps all questions of a categorical event derivable from the
|
||||||
|
single marketId.
|
||||||
|
- `conditionId = NegRiskAdapter.getConditionId(questionId)`
|
||||||
|
= `keccak256(NegRiskAdapter ‖ questionId ‖ 2)`.
|
||||||
|
- `positionId(YES) = NegRiskAdapter.getPositionId(questionId, true)`
|
||||||
|
`positionId(NO) = NegRiskAdapter.getPositionId(questionId, false)` —
|
||||||
|
these match the decimal `clobTokenIds` returned by the Gamma API.
|
||||||
|
|
||||||
|
> **In practice you do not recompute these.** Pull `conditionId` and
|
||||||
|
> `clobTokenIds` straight from Gamma; only call `getPositionId` /
|
||||||
|
> `getConditionId` if you want to verify against on-chain truth.

## 7. End-to-end Python (web3.py) — approve + simulate redeem
|
||||||
|

|
Self-contained, structurally complete. Uses placeholder `0x...` for the

|

it as an `eth_call` simulation.

## 8. Gotchas
|
||||||
|
|
||||||
|
1. **USDC.e ≠ native USDC.** Polymarket exclusively uses **bridged USDC.e**
|
||||||
|
`0x2791…84174`. Approving native Circle USDC `0x3c499…3359` will silently
|
||||||
|
fail every order placement and adapter call. Confirm balance with
|
||||||
|
`usdc.functions.symbol().call() == "USDC"` *and* address match.
|
||||||
|
2. **Two distinct allowances.** You must `approve(USDC.e → NegRiskAdapter)`
|
||||||
|
*and* `setApprovalForAll(CTF → NegRiskAdapter, true)`. The second is
|
||||||
|
needed for `mergePositions`, `redeemPositions`, and `convertPositions`
|
||||||
|
because the adapter pulls your ERC-1155 outcome tokens before burning.
|
||||||
|
Trading additionally requires the same two approvals targeting the
|
||||||
|
**NegRiskCtfExchange** address.
|
||||||
|
3. **Gas estimates (Polygon, ~April 2026 baseline).** Approximate, varies
|
||||||
|
±30% with calldata size:
|
||||||
|
- `splitPosition` ~ 200–250 k gas
|
||||||
|
- `mergePositions` ~ 200–250 k gas
|
||||||
|
- `redeemPositions(N=2)` ~ 150–220 k gas (single binary)
|
||||||
|
- `convertPositions` ~ 250–400 k gas (depends on `indexSet` popcount)
|
||||||
|
At ~50 gwei `maxFeePerGas`, redeem costs roughly $0.005–$0.02 of MATIC.
|
||||||
|
At Polygon gas spikes (>500 gwei) this can rise 10×; size the arb spread
|
||||||
|
accordingly.
|
||||||
|
4. **Resolution dependency on UMA.** Redeem only works after the
|
||||||
|
UmaCtfAdapter has called `reportPayouts` upstream and (for negRisk)
|
||||||
|
the NegRiskOperator has called `reportOutcome`. Until then
|
||||||
|
`redeemPositions` reverts with `MarketNotResolved`/payout-vector-empty.
|
||||||
|
UMA's optimistic oracle has a **2-hour liveness window** (default) per
|
||||||
|
question; disputes extend by days.
|
||||||
|
5. **No-winner / all-NO is an invalid state.** NegRisk *requires* exactly
|
||||||
|
one question per market to resolve YES. Per the adapter docs and audit:
|
||||||
|
if the oracle tries to report a second YES, `reportOutcome` reverts and
|
||||||
|
the market is stuck pending manual operator action; if all questions go
|
||||||
|
NO the system is "designed to prevent" that scenario but has no
|
||||||
|
automatic refund path. Polymarket's stated stance after past disputes
|
||||||
|
has been **no refunds for resolution disagreements**. Architect the
|
||||||
|
strategy so you can hold or sell tokens before final resolution if
|
||||||
|
ambiguity emerges.
|
||||||
|
([NegRisk docs](https://github.com/Polymarket/neg-risk-ctf-adapter/blob/main/docs/NegRiskAdapter.md),
|
||||||
|
[Coindesk – UMA/Polymarket dispute, Mar 2025](https://www.coindesk.com/markets/2025/03/27/polymarket-uma-communities-lock-horns-after-usd7m-ukraine-bet-resolves))
|
||||||
|
6. **Operator-only `safeTransferFrom`.** The adapter's `safeTransferFrom`
|
||||||
|
has an `onlyAdmin` modifier. Don't try to ERC-1155-transfer wrapped
|
||||||
|
positions through the adapter; transfer directly through the underlying
|
||||||
|
ConditionalTokens contract.
|
||||||
|
7. **`negRiskAugmented` events.** When `enableNegRisk` is true, new
|
||||||
|
outcomes (questions) can be appended to a marketId after creation. Your
|
||||||
|
"Σ asks" snapshot can become stale if a new candidate is added between
|
||||||
|
detection and trade — re-pull the event before lifting offers.
|
||||||
|
8. **CLOB order flag.** When placing orders against negRisk markets, you
|
||||||
|
must pass `neg_risk=True` in the order options of `py-clob-client` so
|
||||||
|
the order is signed for the NegRiskCtfExchange (`0xC5d5…80a`) instead
|
||||||
|
of the vanilla CTFExchange. Wrong exchange → orders rejected.

||||||

# Polymarket CLOB Order Signing Cookbook (`py-clob-client`)
|
||||||
|
|
||||||
|
A copy-pasteable reference for signing and submitting Polymarket CLOB orders from
|
||||||
|
Python. Verified against `py-clob-client` **v0.34.6** (released 2026-02-19).
|
||||||
|
|
||||||
|
All citations point at `Polymarket/py-clob-client@main` on GitHub. Update the pin
|
||||||
|
when bumping.

||||||
|
|
||||||
|
## 1. Install
|
||||||
|
|
||||||
|
Pin the exact version your executor was tested against. As of April 2026 the
|
||||||
|
latest published release is **0.34.6**.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pip install py-clob-client==0.34.6
|
||||||
|
```
|
||||||
|
|
||||||
|
Source: <https://pypi.org/project/py-clob-client/0.34.6/> /
|
||||||
|
[`setup.py` L7-L25](https://github.com/Polymarket/py-clob-client/blob/main/setup.py#L7-L25)
|
||||||
|
|
||||||
|
Transitive deps it pulls in (from `setup.py`):
|
||||||
|
|
||||||
|
- `eth-account>=0.13.0`
|
||||||
|
- `eth-utils>=4.1.1`
|
||||||
|
- `poly_eip712_structs>=0.0.1`
|
||||||
|
- `py-order-utils>=0.3.2`
|
||||||
|
- `py-builder-signing-sdk>=0.0.2`
|
||||||
|
- `httpx[http2]>=0.27.0`
|
||||||
|
- `python-dotenv`
|
||||||
|
|
||||||
|
Requires Python **3.9.10+**.
|
||||||
|
|
||||||
|
The HTTP client under the hood is `httpx` (sync). All `client.*` methods are
|
||||||
|
**blocking**. See the `asyncio` pattern in section 7.

## 2. One-Time Setup: Derive L2 API Credentials
|
||||||
|
|
||||||
|
L2 (HMAC) creds — `api_key`, `api_secret`, `api_passphrase` — are deterministic
|
||||||
|
for a given `(wallet, nonce)`. You generate them once and store them. The
|
||||||
|
`create_or_derive_api_creds()` helper tries `POST /auth/api-key` first, and falls
|
||||||
|
back to `GET /auth/derive-api-key` if the key already exists.
|
||||||
|
|
||||||
|
Reference:
|
||||||
|
[`py_clob_client/client.py` L211-L260](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L211-L260)
|
||||||
|
|
||||||
|
```python
|
||||||
|
# scripts/bootstrap_clob_creds.py
|
||||||
|
"""
|
||||||
|
Run ONCE per wallet to mint L2 API credentials, then store the three
|
||||||
|
strings (api_key, api_secret, api_passphrase) in your secret manager.
|
||||||
|
"""
|
||||||
|
import os
|
||||||
|
from py_clob_client.client import ClobClient
|
||||||
|
from py_clob_client.constants import POLYGON
|
||||||
|
|
||||||
|
HOST = "https://clob.polymarket.com"
|
||||||
|
PRIVATE_KEY = os.environ["POLY_PK"] # 0x-prefixed hex
|
||||||
|
CHAIN_ID = POLYGON # 137 (mainnet) or AMOY=80002
|
||||||
|
|
||||||
|
# L1 client = host + chain + key. No creds needed yet.
|
||||||
|
client = ClobClient(HOST, key=PRIVATE_KEY, chain_id=CHAIN_ID)
|
||||||
|
|
||||||
|
# Idempotent: creates if missing, derives if existing. Returns ApiCreds.
|
||||||
|
creds = client.create_or_derive_api_creds()
|
||||||
|
|
||||||
|
print("CLOB_API_KEY =", creds.api_key)
|
||||||
|
print("CLOB_SECRET =", creds.api_secret)
|
||||||
|
print("CLOB_PASS_PHRASE =", creds.api_passphrase)
|
||||||
|
```
|
||||||
|
|
||||||
|
`ApiCreds` is a dataclass with three string fields:
|
||||||
|
[`clob_types.py` L19-L23](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/clob_types.py#L19-L23).
|
||||||
|
|
||||||
|
> Polymarket prints a giant warning that creds **cannot be recovered** if lost
|
||||||
|
> — store them in your secrets backend immediately.
|
||||||
|
> See [`constants.py` L7-L10](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/constants.py#L7-L10).

|

|
||||||
|
## 3. Client Init
|
||||||
|
|
||||||
|
```python
|
||||||
|
import os
|
||||||
|
from py_clob_client.client import ClobClient
|
||||||
|
from py_clob_client.clob_types import ApiCreds
|
||||||
|
from py_clob_client.constants import POLYGON
|
||||||
|
|
||||||
|
client = ClobClient(
|
||||||
|
host="https://clob.polymarket.com",
|
||||||
|
key=os.environ["POLY_PK"], # private key of the *signer* EOA
|
||||||
|
chain_id=POLYGON, # 137
|
||||||
|
creds=ApiCreds(
|
||||||
|
api_key=os.environ["CLOB_API_KEY"],
|
||||||
|
api_secret=os.environ["CLOB_SECRET"],
|
||||||
|
api_passphrase=os.environ["CLOB_PASS_PHRASE"],
|
||||||
|
),
|
||||||
|
signature_type=2, # see table below
|
||||||
|
funder="0xYourPolymarketProxyAddress", # USDC-holding address
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
Constructor signature:
|
||||||
|
[`client.py` L116-L165](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L116-L165).
|
||||||
|
|
||||||
|
### `signature_type`
|
||||||
|
|
||||||
|
The integer is forwarded to `OrderBuilder.__init__` and stamped into the EIP-712
|
||||||
|
order payload as `signatureType`
|
||||||
|
([`order_builder/builder.py` L40-L49](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/order_builder/builder.py#L40-L49),
|
||||||
|
[L143](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/order_builder/builder.py#L143)).
|
||||||
|
|
||||||
|
| `signature_type` | Wallet Model | When to use |
|
||||||
|
| ---------------- | ------------------------------------- | ------------------------------------------------------------------------------------------ |
|
||||||
|
| `0` (default, `EOA`) | Plain EOA / MetaMask / hardware | Signer EOA *is* the funder. USDC and CTF tokens sit on the same address that signs. |
|
||||||
|
| `1` (`POLY_PROXY`) | Polymarket proxy (Magic / email) | Signer EOA is the session key; funds live in a Polymarket-deployed proxy contract. |
|
||||||
|
| `2` (`POLY_GNOSIS_SAFE`) | Gnosis Safe / browser proxy | Signer EOA is an owner; funds live in a Safe / proxy contract. |
|
||||||
|
|
||||||
|
Default if omitted is `EOA` (0). See `EOA` constant in
|
||||||
|
`py_order_utils.model` re-exported via `builder.py` L4.
|
||||||
|
|
||||||
|
### `funder`
|
||||||
|
|
||||||
|
The address that **holds USDC and conditional tokens**. This goes into the
|
||||||
|
`maker` field of the signed order
|
||||||
|
([`builder.py` L132-L144](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/order_builder/builder.py#L132-L144)),
|
||||||
|
while `signer` is set to the address derived from your private key.
|
||||||
|
|
||||||
|
- If `funder` is omitted, it defaults to `signer.address()`.
|
||||||
|
- For arbitrage from a Polymarket UI account, `funder` = your visible Polymarket
|
||||||
|
proxy address (look it up on polygonscan or in the UI), and `key` = the
|
||||||
|
session/EOA key Polymarket gave you.
|
||||||
|
- For a pure EOA setup, leave `funder=None` (or pass the same address as the
|
||||||
|
signer) and use `signature_type=0`.
|
||||||
|
|
||||||
|
### Read-only mode
|
||||||
|
|
||||||
|
Drop `creds`, `key`, `signature_type`, `funder` for L0 (public endpoints only):
|
||||||
|
|
||||||
|
```python
|
||||||
|
client = ClobClient("https://clob.polymarket.com")
|
||||||
|
client.get_order_book(token_id)
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 4. Place an Order
|
||||||
|
|
||||||
|
### 4a. Limit order — GTC (resting)
|
||||||
|
|
||||||
|
Source pattern:
|
||||||
|
[`examples/order.py` L1-L36](https://github.com/Polymarket/py-clob-client/blob/main/examples/order.py).
|
||||||
|
|
||||||
|
```python
|
||||||
|
from py_clob_client.clob_types import OrderArgs, OrderType
|
||||||
|
from py_clob_client.order_builder.constants import BUY, SELL
|
||||||
|
|
||||||
|
order_args = OrderArgs(
|
||||||
|
token_id="71321045679252212594626385532706912750332728571942532289631379312455583992563",
|
||||||
|
price=0.42, # USD per share, between 0.0 and 1.0
|
||||||
|
size=100.0, # shares
|
||||||
|
side=BUY, # or SELL
|
||||||
|
)
|
||||||
|
|
||||||
|
signed = client.create_order(order_args) # builds EIP-712 + signs
|
||||||
|
resp = client.post_order(signed, OrderType.GTC)
|
||||||
|
# resp == {"success": True, "orderID": "0x...", "status": "matched"|"live"|...}
|
||||||
|
```
|
||||||
|
|
||||||
|
`OrderArgs` fields (from
|
||||||
|
[`clob_types.py` L42-L83](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/clob_types.py#L42-L83)):
|
||||||
|
`token_id`, `price`, `size`, `side`, `fee_rate_bps=0`, `nonce=0`,
|
||||||
|
`expiration=0`, `taker=ZERO_ADDRESS`.
|
||||||
|
|
||||||
|
`create_order` automatically:
|
||||||
|
|
||||||
|
- fetches and caches the market's `tick_size` and `neg_risk` flag
|
||||||
|
([`client.py` L402-L448, L492-L535](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L492-L535)),
|
||||||
|
- validates your price against the tick,
|
||||||
|
- picks the correct exchange contract for `neg_risk` markets,
|
||||||
|
- signs an EIP-712 order with `maker=funder`, `signer=EOA`, `signatureType=...`.
|
||||||
|
|
||||||
|
### 4b. Limit order — GTD (good-till-date)
|
||||||
|
|
||||||
|
Source: [`examples/GTD_order.py`](https://github.com/Polymarket/py-clob-client/blob/main/examples/GTD_order.py).
|
||||||
|
|
||||||
|
```python
|
||||||
|
order_args = OrderArgs(
|
||||||
|
token_id="...",
|
||||||
|
price=0.50,
|
||||||
|
size=100.0,
|
||||||
|
side=BUY,
|
||||||
|
expiration="1000000000000", # unix seconds; must be > now+60s
|
||||||
|
)
|
||||||
|
signed = client.create_order(order_args)
|
||||||
|
resp = client.post_order(signed, OrderType.GTD)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4c. FOK (Fill-Or-Kill)
|
||||||
|
|
||||||
|
FOK requires the entire size to fill immediately at the limit price or better,
|
||||||
|
otherwise the whole order is cancelled. Polymarket uses FOK for *market* buys
|
||||||
|
priced in dollars (`MarketOrderArgs.amount`).
|
||||||
|
|
||||||
|
Source: [`examples/market_buy_order.py`](https://github.com/Polymarket/py-clob-client/blob/main/examples/market_buy_order.py).
|
||||||
|
|
||||||
|
```python
|
||||||
|
from py_clob_client.clob_types import MarketOrderArgs, OrderType
|
||||||
|
|
||||||
|
mo = MarketOrderArgs(
|
||||||
|
token_id="...",
|
||||||
|
amount=100.0, # BUY: USDC to spend. SELL: shares to sell.
|
||||||
|
side=BUY,
|
||||||
|
)
|
||||||
|
signed = client.create_market_order(mo)
|
||||||
|
resp = client.post_order(signed, orderType=OrderType.FOK)
|
||||||
|
```
|
||||||
|
|
||||||
|
`MarketOrderArgs` defaults `order_type=OrderType.FOK`
|
||||||
|
([`clob_types.py` L86-L122](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/clob_types.py#L86-L122)).
|
||||||
|
|
||||||
|
### 4d. FAK / IOC (Fill-And-Kill, a.k.a. Immediate-Or-Cancel)
|
||||||
|
|
||||||
|
`OrderType.FAK` is Polymarket's IOC variant — fills as much as possible
|
||||||
|
immediately, cancels the unfilled remainder. Use this for arbitrage legs where
|
||||||
|
partial fills are acceptable.
|
||||||
|
|
||||||
|
```python
|
||||||
|
from py_clob_client.clob_types import OrderArgs, OrderType
|
||||||
|
from py_clob_client.order_builder.constants import BUY
|
||||||
|
|
||||||
|
order_args = OrderArgs(token_id="...", price=0.42, size=100.0, side=BUY)
|
||||||
|
signed = client.create_order(order_args)
|
||||||
|
resp = client.post_order(signed, OrderType.FAK) # IOC behavior
|
||||||
|
```
|
||||||
|
|
||||||
|
Enum values:
|
||||||
|
[`clob_types.py` L11-L16`](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/clob_types.py#L11-L16):
|
||||||
|
|
||||||
|
```python
|
||||||
|
class OrderType(enumerate):
|
||||||
|
GTC = "GTC" # resting limit
|
||||||
|
FOK = "FOK" # all-or-nothing immediate
|
||||||
|
GTD = "GTD" # resting limit with expiry
|
||||||
|
FAK = "FAK" # IOC: fill what you can, cancel rest
|
||||||
|
```
|
||||||
|
|
||||||
|
> **TL;DR for an arbitrage executor**: use `FAK` for legs where you want IOC
|
||||||
|
> semantics on a limit order, and `FOK` for $-denominated market-sweep buys
|
||||||
|
> where you only want the trade if the full notional clears.
|
||||||
|
|
||||||
|
`post_only=True` is only legal with `GTC` / `GTD`
|
||||||
|
([`client.py` L623-L628](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L623-L628)).

## 5. Cancel Orders
|
||||||
|
|
||||||

|
||||||
|
[`examples/cancel_orders.py`](https://github.com/Polymarket/py-clob-client/blob/main/examples/cancel_orders.py).
|
||||||
|
|
||||||
|
```python
|
||||||
|
# single
|
||||||
|
client.cancel(order_id="0xabc...")
|
||||||
|
|
||||||
|
# batch
|
||||||
|
client.cancel_orders(["0xabc...", "0xdef..."])
|
||||||
|
|
||||||
|
# all open orders for this API key
|

|
client.cancel_all()
|

|
|
||||||

# all orders on a market or token
|
||||||
|
client.cancel_market_orders(market="0x...condition_id...", asset_id="")
|
||||||
|
client.cancel_market_orders(market="", asset_id="<token_id>")
|

||||||
|
## 6. Get Positions / Open Orders / Fills
|
||||||
|
|
||||||
|
py-clob-client does **not** ship a `get_positions()` method — Polymarket exposes
|
||||||
|
"positions" via the Data-API (separate service). Within `py-clob-client` you use
|
||||||
|
**balance/allowance** for current token holdings, **`get_orders`** for open
|
||||||
|
orders, and **`get_trades`** for fills.
|
||||||
|
|
||||||
|
### Balance / position per token
|
||||||
|
|
||||||
|
Source: [`examples/get_balance_allowance.py`](https://github.com/Polymarket/py-clob-client/blob/main/examples/get_balance_allowance.py).
|
||||||
|
|
||||||
|
```python
|
||||||
|
from py_clob_client.clob_types import BalanceAllowanceParams, AssetType
|
||||||
|
|
||||||
|
# USDC balance + exchange allowance
|
||||||
|
usdc = client.get_balance_allowance(
|
||||||
|
BalanceAllowanceParams(asset_type=AssetType.COLLATERAL)
|
||||||
|
)
|
||||||
|
|
||||||
|
# Conditional-token (outcome share) balance for one token_id
|

|
shares = client.get_balance_allowance(

|
BalanceAllowanceParams(
|
||||||
|
asset_type=AssetType.CONDITIONAL,
|
||||||
|
token_id="71321045679252212594626385532706912750332728571942532289631379312455583992563",

|

|
from the client.

### Open orders
|
||||||
|
|
||||||
|
```python
|
||||||
|
from py_clob_client.clob_types import OpenOrderParams
|
||||||
|
|
||||||
|
orders = client.get_orders(OpenOrderParams()) # all
|
||||||
|
orders = client.get_orders(OpenOrderParams(market="0x...condition")) # one market
|
||||||
|
orders = client.get_orders(OpenOrderParams(asset_id="<token_id>")) # one token
|
||||||
|
```
|
||||||
|
|
||||||
|
`get_orders` paginates internally with `next_cursor`
|
||||||
|
([`client.py` L750-L769](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L750-L769)).

## 7. Multi-Leg / Parallel Order Submission
|
||||||
|
|
||||||
|
`py-clob-client` is **synchronous** (it uses `httpx` in blocking mode). For
|
||||||
|
arbitrage you have two good options:
|
||||||
|
|
||||||
|
### Option A — Server-side batch (preferred when atomicity matters less)
|
||||||
|
|
||||||
|
`post_orders` ships N orders in one HTTP round-trip. Lower latency than N
|
||||||
|
parallel calls, but the server processes them serially.
|
||||||
|
|
||||||
|
Source: [`examples/orders.py`](https://github.com/Polymarket/py-clob-client/blob/main/examples/orders.py).
|
||||||
|
|
||||||
|
```python
|
||||||
|
from py_clob_client.clob_types import OrderArgs, PostOrdersArgs, OrderType
|
||||||
|
from py_clob_client.order_builder.constants import BUY, SELL
|
||||||
|
|
||||||
|
resp = client.post_orders([
|
||||||
|
PostOrdersArgs(
|
||||||
|
order=client.create_order(OrderArgs(
|
||||||
|
token_id="...YES_TOKEN_ID...",
|
||||||
|
price=0.50, size=100, side=BUY)),
|
||||||
|
orderType=OrderType.FAK,
|
||||||
|
postOnly=False,
|
||||||
|
),
|
||||||
|
PostOrdersArgs(
|
||||||
|
order=client.create_order(OrderArgs(
|
||||||
|
token_id="...NO_TOKEN_ID...",
|
||||||
|
price=0.51, size=100, side=BUY)),
|
||||||
|
orderType=OrderType.FAK,
|
||||||
|
postOnly=False,
|
||||||
|
),
|
||||||
|
])
|
||||||
|
```
|
||||||
|
|
||||||
|
Implementation: [`client.py` L592-L621](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L592-L621).
|
||||||
|
|
||||||
|
### Option B — `asyncio.gather` over a thread pool (true parallel HTTP)
|
||||||
|
|
||||||
|
When you want each leg to be a separate request fired concurrently (useful for
|
||||||
|
hitting the matching engine at the same time across markets), wrap the sync
|
||||||
|
client with `loop.run_in_executor`:
|
||||||
|
|
||||||
|
```python
|
||||||
|
import asyncio
|
||||||
|
from concurrent.futures import ThreadPoolExecutor
|
||||||
|
from py_clob_client.clob_types import OrderArgs, OrderType
|
||||||
|
from py_clob_client.order_builder.constants import BUY
|
||||||
|
|
||||||
|
# One executor for the whole process is fine. Size = max parallel legs.
|
||||||
|
_EXECUTOR = ThreadPoolExecutor(max_workers=16)
|
||||||
|
|
||||||
|
async def submit_leg(client, order_args: OrderArgs, order_type: OrderType):
|
||||||
|
loop = asyncio.get_running_loop()
|
||||||
|
# create_order signs (CPU + 1 cached HTTP call for tick/neg_risk),
|
||||||
|
# post_order does the actual order POST.
|
||||||
|
signed = await loop.run_in_executor(_EXECUTOR, client.create_order, order_args)
|
||||||
|
return await loop.run_in_executor(
|
||||||
|
_EXECUTOR, client.post_order, signed, order_type
|
||||||
|
)
|
||||||
|
|
||||||
|
async def execute_arb(client, legs: list[tuple[OrderArgs, OrderType]]):
|
||||||
|
return await asyncio.gather(
|
||||||
|
*(submit_leg(client, args, ot) for args, ot in legs),
|
||||||
|
return_exceptions=True, # don't let one failure cancel the others
|
||||||
|
)
|
||||||
|
|
||||||
|
# Usage
|
||||||
|
legs = [
|
||||||
|
(OrderArgs(token_id=YES, price=0.50, size=100, side=BUY), OrderType.FAK),
|
||||||
|
(OrderArgs(token_id=NO, price=0.51, size=100, side=BUY), OrderType.FAK),
|
||||||
|
]
|
||||||
|
results = asyncio.run(execute_arb(client, legs))
|
||||||
|
```
|
||||||
|
|
||||||
|
Notes:
|
||||||
|
|
||||||
|
- The `ClobClient` instance is safe to share across threads for read paths and
|
||||||
|
for `post_order`. Each call constructs its own `httpx` request.
|
||||||
|
- Pre-warm tick/`neg_risk` caches by calling `client.get_tick_size(token_id)`
|
||||||
|
and `client.get_neg_risk(token_id)` once at startup so the hot path skips two
|
||||||
|
HTTP round trips per `create_order`. Caches live on the client
|
||||||
|
([`client.py` L156-L160, L402-L448](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L402-L448)).
|
||||||
|
- The tick-size cache TTL is configurable via the `tick_size_ttl` ctor arg
|
||||||
|
(default 300s).

||||||

## 8. NegRisk Markets
|
||||||
|
|
||||||
|
NegRisk ("negative-risk") markets are Polymarket's multi-outcome markets where
|
||||||
|
the YES tokens of all outcomes sum to ~$1. They use a **different exchange
|
||||||
|
contract** than vanilla binary markets, but the SDK handles the routing for you.
|
||||||
|
|
||||||
|
### What you do NOT need to do
|
||||||
|
|
||||||
|
`OrderArgs` is **identical** for negRisk and vanilla tokens — you still pass
|
||||||
|
`token_id`, `price`, `size`, `side`. There is no `neg_risk` field on
|
||||||
|
`OrderArgs`.
|
||||||
|
|
||||||
|
### What the SDK does behind the scenes
|
||||||
|
|
||||||
|
When you call `client.create_order(...)`, it:
|
||||||
|
|
||||||
|
1. Calls `GET /neg-risk?token_id=...` to learn whether the token belongs to a
|
||||||
|
negRisk market (cached forever per `token_id` —
|
||||||
|
[`client.py` L441-L448](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L441-L448)).
|
||||||
|
2. Calls `get_contract_config(chain_id, neg_risk=True/False)` to pick the right
|
||||||
|
exchange address ([`builder.py` L146-L154](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/order_builder/builder.py#L146-L154)).
|
||||||
|
3. Signs the EIP-712 payload against that exchange's domain separator.
|
||||||
|
|
||||||
|
### When you DO need to override
|
||||||
|
|
||||||
|
If you already know the market is negRisk and want to skip the lookup, pass
|
||||||
|
`PartialCreateOrderOptions`:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from py_clob_client.clob_types import PartialCreateOrderOptions
|
||||||
|
|
||||||
|
signed = client.create_order(
|
||||||
|
order_args,
|
||||||
|
options=PartialCreateOrderOptions(neg_risk=True, tick_size="0.01"),
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
(definition:
|
||||||
|
[`clob_types.py` L165-L172](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/clob_types.py#L165-L172).)
|
||||||
|
|
||||||
|
### Allowances (one-time, per signer)
|
||||||
|
|
||||||
|
For EOAs (`signature_type=0`) you must approve **both** the vanilla CTF Exchange
|
||||||
|
**and** the NegRisk CTF Exchange + NegRisk Adapter on Polygon mainnet.
|
||||||
|
Magic/proxy wallets (`signature_type=1` or `2`) have allowances set
|
||||||
|
automatically. From the README:
|
||||||
|
|
||||||
|
| Token | Approve for |
|
||||||
|
| --------------------------------------- | --------------------------------------------- |
|
||||||
|
| USDC (`0x2791Bca1...A84174`) | `0x4bFb41d5...8B8982E` (CTF Exchange) |
|
||||||
|
| Conditional Tokens (`0x4D97DCd9...476045`) | `0xC5d563A3...220f80a` (NegRisk Exchange) |
|
||||||
|
| | `0xd91E80cF...0DA35296` (NegRisk Adapter) |
|
||||||
|
|
||||||
|

## 9. Error Handling
|
||||||
|
|
||||||
|
### Exception hierarchy
|
||||||
|
|
||||||
|
All client exceptions live in
|
||||||
|
[`py_clob_client/exceptions.py`](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/exceptions.py):
|
||||||
|
|
||||||
|
```python
|
||||||
|
class PolyException(Exception):
|
||||||
|
msg: str
|
||||||
|
|
||||||
|
class PolyApiException(PolyException):
|
||||||
|
status_code: int | None # HTTP status from the failed response
|
||||||
|
error_msg: dict | str # parsed JSON or raw text body
|
||||||
|
```
|
||||||
|
|
||||||
|
`PolyApiException` is raised inside `http_helpers/helpers.py` for any non-2xx
|
||||||
|
HTTP response. `httpx` exceptions (`httpx.RequestError`,
|
||||||
|
`httpx.TimeoutException`, `httpx.HTTPError`) can leak through on network/DNS
|
||||||
|
failures.
|
||||||
|
|
||||||
|
### Recommended catch ladder
|
||||||
|
|
||||||
|
```python
|
||||||
|
import httpx
|
||||||
|
from py_clob_client.exceptions import PolyApiException, PolyException
|
||||||
|
|
||||||
|
try:
|
||||||
|
resp = client.post_order(signed, OrderType.FAK)
|
||||||
|
except PolyApiException as e:
|
||||||
|
# API-layer failure: invalid price, insufficient balance, market closed, 4xx/5xx
|
||||||
|
if e.status_code in (429, 502, 503, 504):
|
||||||
|
# rate-limited or transient — retry with backoff
|
||||||
|
...
|
||||||
|
elif e.status_code in (400, 422):
|
||||||
|
# client error — DO NOT retry; surface to operator
|
||||||
|
...
|
||||||
|
else:
|
||||||
|
...
|
||||||
|
except (httpx.TimeoutException, httpx.RequestError) as e:
|
||||||
|
# Network-layer failure — safe to retry idempotently if you used a fresh nonce
|
||||||
|
...
|
||||||
|
except PolyException as e:
|
||||||
|
# Local SDK validation (e.g., invalid tick size, bad side)
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
### Retry guidance for an arbitrage executor
|
||||||
|
|
||||||
|
- **Idempotency**: Polymarket assigns the order ID on the server side from the
|
||||||
|
EIP-712 hash, so re-posting the *exact same signed payload* is naturally
|
||||||
|
idempotent for `GTC`/`GTD`. For `FAK`/`FOK`, the hash includes the salt so a
|
||||||
|
fresh `create_order` call generates a *new* order — only retry if you
|
||||||
|
confirmed via `get_orders` / `get_trades` that the original did not fill.
|
||||||
|
- **Cap retries at 1-2** for any order-placement call; latency-sensitive
|
||||||
|
arbitrage prefers fast failure over duplicated risk.
|
||||||
|
- **Pre-flight checks** before any loop: `client.get_balance_allowance(...)`
|
||||||
|
for both legs, `client.get_tick_size(token_id)` to warm the cache.
|
||||||
|
- **Heartbeat-based dead-man switch**: `client.post_heartbeat(heartbeat_id)`
|
||||||
|
cancels all your orders if no heartbeat arrives within 10s — useful as a
|
||||||
|
safety net while the executor is running
|
||||||
|
([`client.py` L713-L727](https://github.com/Polymarket/py-clob-client/blob/main/py_clob_client/client.py#L713-L727)).
|
||||||
|
|
||||||
|
### Common API-side rejection reasons
|
||||||
|
|
||||||
|
- `not enough balance / allowance` — top up USDC or re-run the allowance script.
|
||||||
|
- `min size not met` — `OrderBookSummary.min_order_size`.
|
||||||
|
- `tick size invalid` — your `price` doesn't fit the market's tick. Use
|
||||||
|
`client.get_tick_size(token_id)` and round.
|
||||||
|
- `market not active` — market is paused, resolved, or closed.
|
||||||
|
- `order expired` — for `GTD`, `expiration` must be > `now + 60s`.

* Polymarket Strategy Lab — pure browser-side backtester.
|
||||||
|
*
|
||||||
|
* Loads 100+ REAL resolved Polymarket categorical events from docs/data/
|
||||||
|
* historical-events.json, runs five different strategies against them,
|
||||||
|
* and shows you honest results — no cherry-picking.
|
||||||
|
*
|
||||||
|
* Each strategy is a pure function: given an event (outcomes + their
|
||||||
|
* last-trade prices + who actually won), it returns what it would have
|
||||||
|
* bought, how much it paid, and how much it got back. The backtest runner
|

|
* tallies these across every event.
|
||||||

* The strategies live here, open and readable. You can read exactly what

<h3>The possible answers and what the market thinks of each</h3>
|
||||||
|
<p>
|
||||||
|
Each row is one possible answer. The percentage is the market's
|
||||||
|
current estimate of that answer being correct — because a $0.72
|
||||||
|
share pays $1 when it wins, it must be priced at roughly a 72%
|
||||||
|
probability.

<h2>Questions you probably have</h2>

<details class="faq-item" open>
|
||||||
|
<summary>What is Polymarket?</summary>
|
||||||
|
<p>
|
||||||
|
Polymarket is an online betting site for real-world questions —
|
||||||
|
elections, sports, Fed meetings, crypto prices, award shows.
|
||||||
|
Each question has a list of possible answers, and each answer is
|
||||||
|
a share you can buy. When the real-world event resolves, shares
|
||||||
|
of the winning answer pay exactly <strong>$1</strong>, and every
|
||||||
|
other share pays <strong>$0</strong>. The price of a share is
|
||||||
|
basically the market's guess at how likely that answer is.
|
||||||
|
</p>
|
||||||
|
</details>
|
||||||
|
|
||||||
|
<details class="faq-item">
|
||||||
|
<summary>Why does "buying one share of every answer" always pay $1?</summary>
|
||||||
|
<p>
|
||||||
|
Because exactly one answer can win. If the event has four possible
|
||||||
|
outcomes (say: "25 bps up", "no change", "25 bps down", "50+ bps
|
||||||
|
down") and you own one share of each, then <em>whatever</em>
|
||||||
|
happens, you hold the winning share — and that share pays $1.
|
||||||
|
The other three pay $0. You paid for all four, but only the
|
||||||
|
winner matters.
|
||||||
|
</p>
|
||||||
|
</details>
|
||||||
|
|
||||||
|
<details class="faq-item">
|
||||||
|
<summary>So where's the free money?</summary>
|
||||||
|
<p>
|
||||||
|
If the <em>total</em> cost of buying one of every answer drops
|
||||||
|
below $1, you're guaranteed to make the difference. Example: if
|
||||||
|
the four answers cost 60¢, 30¢, 7¢, and 2¢ — total 99¢ — you
|
||||||
|

<summary>Why am I seeing "no free money" every time I check?</summary>
|

|
<p>
|

|
Because the math is public and professional trading bots watch it
|
||||||
|
too. The moment the total dips below $1, they instantly buy every
|
||||||
|
outcome and push the price back up. Arbitrage on big, popular
|
||||||
|
Polymarket events is usually closed within milliseconds. A browser
|
||||||
|
page running on your laptop is not going to beat them.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
This demo exists to show <em>how</em> the math works and
|
||||||
|
<em>how often</em> the opportunities actually appear. Watching it
|
||||||
|
produce nothing for 30 minutes is more informative than a fake
|
||||||
|
demo that flashes profits every second.

<summary>Is this actually live?</summary>

<p>
|

Yes. Your browser opens a WebSocket to Polymarket's public CLOB
|
||||||
|
(the same one their website uses) and receives real price updates
|
||||||
|
every few milliseconds. The number of price updates received is
|
||||||
|
in the footer below — it ticks up in real time. The event list
|
||||||
|
is refreshed hourly by a GitHub Action so you're always looking
|
||||||
|
at currently-open markets.

<summary>Does this page actually trade?</summary>
|

|
<p>
|
||||||
|
<strong>No.</strong> This page is read-only. It does not hold money,
|
||||||
|
sign transactions, or submit orders. It's a live view of the math.
|
||||||
|
The full Python bot in the GitHub repo can submit real orders, but
|
||||||
|
only with explicit operator configuration and hard risk caps —
|
||||||
|
and even then it defaults to a dry-run mode that logs orders
|
||||||
|
instead of broadcasting them.

Because the same skills — reading real-time market data, writing
|
||||||
|
low-latency async pipelines, building production-grade risk
|
||||||
|
systems, and shipping interactive demos that explain themselves —
|
||||||
|
solve a lot of other, more lucrative problems than retail
|
||||||
|
arbitrage. If you have a problem that looks like "connect to a
|
||||||
|
streaming API, do math on every event, take action under hard
|
||||||
|
constraints," that's this whole project in one sentence.

<h2><span class="rule"></span>The arbitrage, in one paragraph</h2>
|
||||||
|
<p>
|
||||||
|
Polymarket hosts <em>categorical</em> events — "Who wins the 2028 US Election?" —
|
||||||
|
where every outcome trades as its own YES token on a public CLOB. Because
|
||||||
|
exactly one outcome must win, the fair prices across all outcomes are bound
|
||||||
|
to sum to exactly <strong>$1</strong>. When the sum of best-asks drops below
|
||||||
|
$1, buying one share of every outcome locks in a guaranteed $1 payout on
|
||||||
|
resolution. The challenge isn't detecting the mispricing — it's racing
|
||||||
|
faster bots, walking order-book depth honestly so edge isn't a fantasy at
|
||||||
|
top-of-book, paying realistic Polygon gas, and surviving UMA resolution
|
||||||
|
disputes that can void a "risk-free" basket. This project builds the full
|
||||||
|
pipeline for that strategy, end to end, with paper mode as the primary
|
||||||
|
validation tool.

<h3>Gamma REST discovery</h3>
|

<p>Paginates Polymarket's <code>/events</code> endpoint, filters to active

NegRisk categoricals, normalizes into pydantic models, upserts idempotently

into SQLite, and marks dropped events inactive.</p>

snapshots and <code>price_change</code> deltas against a per-token sorted
|

price ladder. Shards across sockets, keeps connections alive with PING/PONG,

reconnects with exponential backoff.</p>

<h3>Opportunity engine</h3>
|

<p>On every book tick, walks depth across all outcomes of the affected

event, computes the basket size that maximizes net expected profit after
|
||||||
|
fees and amortised gas, emits a typed <code>Opportunity</code> record

window model "being beaten by a faster bot." Writes baskets + per-leg fills

across all legs in parallel, attempts to unwind any partial fill, calls

<code>NegRiskAdapter.redeemPositions</code> on the winning leg. Default

open baskets (global and per-event), daily loss stop, kill-switch file,
|

<h2><span class="rule"></span>What this is (and isn't)</h2>
|

|
<p>
|
||||||
|
This is a working engineering project — a reference for how to structure a
|
||||||
|
latency-sensitive async trading bot with disciplined risk gates, honest
|
||||||
|
simulated fills, and a testable core. It is <strong>not</strong> a
|
||||||
|
get-rich tool. The retail edge in public prediction-market arbitrage has
|
||||||
|
mostly been competed away by professional market makers with colocation,
|
||||||
|
custom hardware, and seven-figure working capital. Paper mode here exists
|
||||||
|
specifically to answer the question <em>is there any edge left for a solo
|
||||||
|
Python bot</em>, before a single dollar is risked.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The architecture transfers cleanly to any order-book venue (Kalshi,
|
||||||
|
Manifold, CEX spot markets) — swap the REST + WS adapters and the
|
||||||
|
engine keeps working.

<h2>What you're looking at, in plain English</h2>
|
||||||
|
<p>
|
||||||
|
These events are real Polymarket markets that have already ended
|
||||||
|
in the last few weeks. For each one, we know who won and we have
|
||||||
|
the actual price of every outcome at every moment before the
|
||||||
|
market closed. The page runs a trading strategy on every event
|
||||||
|
and adds up how much money you would have made or lost.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The <strong>"trade at prices from"</strong> selector above is the
|
||||||
|
important knob. Prices right before a market closes tend to be
|
||||||
|
correct (because everyone already knows the answer). Prices a
|
||||||
|
day or more earlier are often noticeably off — and that's where
|
||||||
|
real arbitrage lives. Try clicking the different time windows
|
||||||
|
and watch the numbers change.
|
||||||
|

||||||

||||||
|
<strong>Every price on this page is a real price Polymarket
|
||||||
|
recorded.</strong> Pulled from their public CLOB price-history
|
||||||
|
API. No estimates, no math tricks. You can verify every trade
|
||||||
|
by looking up the event on polymarket.com.

## 1. 项目简介
|
||||||
|
|
||||||
|
**Polymarket NegRisk 多结果套利机器人**。Polymarket 的某些分类事件（例如"2028 大选谁赢"）每个结果独立挂牌交易。当**所有结果的卖一价加总 < $1** 时，买入一整套结果，结算时一定收回 $1 → **无风险套利**。
|
||||||
|
|
||||||
|
本机器人扫描所有活跃 negRisk 事件，实时计算套利空间，提供两种模式：
|
||||||
|
|
||||||
|
| 模式 | 资金风险 | 用途 |
|
||||||
|
|------|---------|------|
|
||||||
|
| **Paper** | $0 | 模拟成交，验证策略，观察 PnL |
|
||||||
|
| **Live** | 实盘资金 | 真实下单，需提供钱包私钥 |
|
||||||
|
|
||||||

|
## 3. 快速安装
|
||||||
|
|
||||||
|
### 3.1 克隆项目
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git clone https://github.com/matthewnyc2/arbitrage
|
||||||
|
cd arbitrage
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.2 创建虚拟环境
|
||||||
|
|
||||||
|
**Windows (PowerShell)**：
|
||||||
|
```powershell
|
||||||
|
python -m venv .venv
|
||||||
|
.\.venv\Scripts\Activate.ps1
|
||||||
|
```
|
||||||
|
|
||||||
|
**Linux / macOS**：
|
||||||
|
```bash
|
||||||
|
python3 -m venv .venv
|
||||||
|
source .venv/bin/activate
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.3 安装依赖
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pip install -e ".[dev]"
|
||||||
|
```
|
||||||
|
|
||||||
|
> **⚠️ 重要**：默认会装 `websockets>=13.0`，pip 可能会拉到 **15.x** 版本，但该版本与项目不兼容（参见 [§10.3 websockets 版本问题](#103-websockets-版本问题)）。**显式锁版本**：
|
||||||
|
> ```bash
|
||||||
|
> pip install "websockets==14.2"
|
||||||
|
> ```
|
||||||
|
|
||||||
|
### 3.4 验证安装
|
||||||
|
|
||||||
|
```bash
|
||||||
|
arb --help
|
||||||
|
```
|
||||||
|
|
||||||
|
应显示：`init / discover / scan / web / resolve` 五个子命令。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. 首次配置
|
||||||
|
|
||||||
|
### 4.1 复制环境变量模板
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cp .env.example .env
|
||||||
|
```
|
||||||
|
|
||||||
|
`.env` 关键字段（Paper 模式默认值即可运行）：
|
||||||
|
|
||||||
|
```ini
|
||||||
|
ARB_MODE=paper # paper = 模拟盘；live = 实盘
|
||||||
|
ARB_CLOB_HOST=https://clob.polymarket.com
|
||||||
|
ARB_GAMMA_HOST=https://gamma-api.polymarket.com
|
||||||
|
ARB_PROXY= # 国内用户填代理，见下文
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4.2 网络代理
|
||||||
|
|
||||||
|
**国内 / 防火墙环境下必须配置**，否则 `arb discover` 会报 `httpx.ConnectTimeout`。
|
||||||
|
|
||||||
|
**PowerShell 临时设置**（仅当前会话）：
|
||||||
|
```powershell
|
||||||
|
$env:HTTPS_PROXY="http://127.0.0.1:7890" # 改成你的代理地址
|
||||||
|
$env:HTTP_PROXY="http://127.0.0.1:7890"
|
||||||
|
```
|
||||||
|
|
||||||
|
**永久设置**（写入 `.env`）：
|
||||||
|
```ini
|
||||||
|
ARB_PROXY=http://127.0.0.1:7890
|
||||||
|
```
|
||||||
|
|
||||||
|
> **常见代理端口**：Clash 默认 7890，V2Ray 默认 10809，SSR 默认 1080。
|
||||||
|
>
|
||||||
|
> 配置完成后 httpx（REST）和 websockets（WS）都会通过代理连接。
|
||||||
|
|
||||||
|
### 4.3 验证代理可用
|
||||||
|
|
||||||
|
```bash
|
||||||
|
arb discover
|
||||||
|
```
|
||||||
|
|
||||||
|
预期输出：
|
||||||
|
```
|
||||||
|
seen=2000 negRisk=928 upserted=894 malformed=34
|
||||||
|
```
|
||||||
|
|
||||||
|
如果仍超时，回到 [§10.1 网络连通性](#101-网络连通性)。

|
| 面板 | 显示内容 |
|
||||||
|
|------|---------|
|
||||||
|
| **Paper PnL** | 已实现盈亏、各状态组合数、Kill Switch 按钮 |
|
||||||
|
| **Baskets** | 最近 25 个组合：ID、事件、份数、成本、状态、PnL |
|
||||||
|
| **Recent Opportunities** | 最近 25 个检测到的机会：Σ asks、净边际、最大组合、预期利润 |
|
||||||
|
|
||||||
|
### 7.2 关键指标解读
|
||||||
|
|
||||||
|
**Σ asks < $1** → 存在套利空间。典型值：
|
||||||
|
- `0.98` → 净边际 ~2%（扣费前）
|
||||||
|
- `0.95` → 净边际 ~5%（扣费前）
|
||||||
|
- `< 0.90` → 非常罕见的深度套利
|
||||||
|
|
||||||
|
**net edge bps**：扣除手续费 + 分摊 gas 后的净边际。低于 50 bps 会被 `ARB_MIN_NET_EDGE_BPS` 过滤。
|
||||||
|
|
||||||
|
**status**：
|
||||||
|
| 状态 | 含义 |
|
||||||
|
|------|------|
|
||||||
|
| `pending_resolution` | 等待事件结算 |
|
||||||
|
| `redeemed` | 已结算，PnL 入账 |
|
||||||
|
| `failed` | 部分腿未成交（paper 模拟时深度消失） |
|
||||||
|
| `invalid` | 事件被标记为无效 |
|
||||||
|
|
||||||
|
### 7.3 Kill Switch
|
||||||
|
|
||||||
|
仪表板右下角红色 **kill** 按钮，点击后立即创建 `./KILL` 文件，执行器会拒绝所有新单。再次点击 **unkill** 删除文件即可恢复。
|
||||||
|
|
||||||
|
也可在终端手动：
|
||||||
|
```bash
|
||||||
|
# Windows
|
||||||
|
New-Item -Path .\KILL -ItemType File
|
||||||
|
|
||||||
|
# Linux/macOS
|
||||||
|
touch ./KILL
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 8. 切换到 Live 模式
|
||||||
|
|
||||||
|
### 8.1 准备工作
|
||||||
|
|
||||||
|
1. **专用钱包**：在 Polygon 上创建一个新的 EOA，**不要复用个人钱包**
|
||||||
|
2. **充值**：向钱包转入 USDC.e（建议 ≥ $200，含 gas）
|
||||||
|
3. **批准授权**：按 `docs/api/order-signing.md` §8 的脚本，对 CTF Exchange + NegRisk Exchange + NegRisk Adapter 三个合约授权
|
||||||
|
|
||||||
|
### 8.2 派生 L2 API 凭证
|
||||||
|
|
||||||
|
按 `docs/api/order-signing.md` §2 的 `bootstrap_clob_creds.py` 脚本执行一次，生成：
|
||||||
|
- `CLOB_API_KEY`
|
||||||
|
- `CLOB_SECRET`
|
||||||
|
- `CLOB_PASSPHRASE`
|
||||||
|
|
||||||
|
**这三个凭证无法恢复，丢失需重新派生。**
|
||||||
|
|
||||||
|
### 8.3 修改 `.env`
|
||||||
|
|
||||||
|
```ini
|
||||||
|
ARB_MODE=live
|
||||||
|
ARB_PRIVATE_KEY=0x... # 钱包私钥（0x 前缀）
|
||||||
|
ARB_FUNDER_ADDRESS=0x... # 资金地址（EOA 模式 = 私钥对应地址）
|
||||||
|
ARB_SIGNATURE_TYPE=0 # 0=EOA, 1=Polymarket proxy, 2=Gnosis Safe
|
||||||
|
ARB_API_KEY=...
|
||||||
|
ARB_API_SECRET=...
|
||||||
|
ARB_API_PASSPHRASE=...
|
||||||
|
|
||||||
|
# 风险上限（强烈建议保持默认值）
|
||||||
|
ARB_MAX_BASKET_USD=50
|
||||||
|
ARB_MAX_OPEN_BASKETS=3
|
||||||
|
ARB_DAILY_LOSS_STOP_USD=100
|
||||||
|
```
|
||||||
|
|
||||||
|
### 8.4 首次实盘（强烈建议 dry_run 验证）
|
||||||
|
|
||||||
|
**第 1 步**：先用 dry_run 验证签名链路：
|
||||||
|
```python
|
||||||
|
# 在 Python REPL 中手动测试
|
||||||
|
from arbitrage.engine.live_executor import LiveExecutor, RiskLimits
|
||||||
|
from arbitrage.book.l2 import BookRegistry
|
||||||
|
books = BookRegistry()
|
||||||
|
ex = LiveExecutor(books=books, dry_run=True) # 只签名不提交
|
||||||
|
```
|
||||||
|
|
||||||
|
**第 2 步**：把 `cli.py:87` 的 `dry_run=False` 保持不变（默认就是 False），但**先把 `ARB_MAX_BASKET_USD` 设为 `5`**：
|
||||||
|
```ini
|
||||||
|
ARB_MAX_BASKET_USD=5
|
||||||
|
ARB_MAX_OPEN_BASKETS=1
|
||||||
|
```
|
||||||
|
|
||||||
|
**第 3 步**：观察 1–2 天无异常后，再逐步放大到默认值。
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 9. 监控与运维
|
||||||
|
|
||||||
|
### 9.1 日志
|
||||||
|
|
||||||
|
日志写在 `logs/arbitrage.jsonl`（结构化 JSON，每天 0 点轮转，保留 7 天）。
|
||||||
|
|
||||||
|
**实时查看**：
|
||||||
|
```bash
|
||||||
|
# Linux/macOS
|
||||||
|
tail -f logs/arbitrage.jsonl | jq .
|
||||||
|
|
||||||
|
# Windows PowerShell
|
||||||
|
Get-Content logs\arbitrage.jsonl -Wait
|
||||||
|
```
|
||||||
|
|
||||||
|
**按事件过滤**：
|
||||||
|
```bash
|
||||||
|
grep "new_market" logs/arbitrage.jsonl | tail -20
|
||||||
|
```
|
||||||
|
|
||||||
|
### 9.2 数据库
|
||||||
|
|
||||||
|
位置：`./arbitrage.db`（SQLite + WAL 模式）
|
||||||
|
|
||||||
|
**直接查询**：
|
||||||
|
```bash
|
||||||
|
sqlite3 arbitrage.db "SELECT status, COUNT(*) FROM baskets GROUP BY status;"
|
||||||
|
sqlite3 arbitrage.db "SELECT * FROM opportunities ORDER BY detected_at DESC LIMIT 10;"
|
||||||
|
```
|
||||||
|
|
||||||
|
**备份**：
|
||||||
|
```bash
|
||||||
|
cp arbitrage.db arbitrage.db.bak-$(date +%Y%m%d)
|
||||||
|
```
|
||||||
|
|
||||||
|
**重置**（清空所有 paper 数据）：
|
||||||
|
```bash
|
||||||
|
rm arbitrage.db
|
||||||
|
arb init
|
||||||
|
arb discover
|
||||||
|
```
|
||||||
|
|
||||||
|
### 9.3 进程监控
|
||||||
|
|
||||||
|
**检查运行中的 arb 进程**：
|
||||||
|
```powershell
|
||||||
|
# Windows
|
||||||
|
Get-Process | Where-Object { $_.Name -eq "python" -and $_.Path -like "*Python312*" }
|
||||||
|
|
||||||
|
# Linux
|
||||||
|
ps aux | grep arb
|
||||||
|
```
|
||||||
|
|
||||||
|
**查看资源占用**：
|
||||||
|
```bash
|
||||||
|
# 内存占用（正常 100-300 MB）
|
||||||
|
Get-Process python | Select-Object Id, @{n='Mem(MB)';e={[int]$_.WorkingSet64/1MB}}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 9.4 升级
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd arbitrage
|
||||||
|
git pull
|
||||||
|
pip install -e ".[dev]"
|
||||||
|
# 重启 arb scan / arb web
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 10. 故障排查
|
||||||
|
|
||||||
|
### 10.1 网络连通性
|
||||||
|
|
||||||
|
**症状**：`httpx.ConnectTimeout`，`arb discover` 卡住。
|
||||||
|
|
||||||
|
**排查**：
|
||||||
|
```powershell
|
||||||
|
Test-NetConnection -ComputerName gamma-api.polymarket.com -Port 443
|
||||||
|
```
|
||||||
|
|
||||||
|
如果失败，确认 `ARB_PROXY` 设置正确，或切换代理节点。
|
||||||
|
|
||||||
|
### 10.2 WebSocket 反复重连
|
||||||
|
|
||||||
|
**症状**：`ws disconnect (TimeoutError); reconnecting in 1.0s` 大量重复。
|
||||||
|
|
||||||
|
**根因**：WebSocket 没有走代理。
|
||||||
|
|
||||||
|
**修复**：确认 `.env` 中设置了 `ARB_PROXY=http://...`，代码会自动通过 HTTP CONNECT 隧道建立 WS 连接。
|
||||||
|
|
||||||
|
### 10.3 websockets 版本问题
|
||||||
|
|
||||||
|
**症状**：`AttributeError: 'ClientConnection' object has no attribute 'recv_messages'`，或 `got an unexpected keyword argument 'proxy'`。
|
||||||
|
|
||||||
|
**根因**：`websockets 15.0` 与项目不兼容。
|
||||||
|
|
||||||
|
**修复**：
|
||||||
|
```bash
|
||||||
|
pip install "websockets==14.2"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 10.4 日志 PermissionError
|
||||||
|
|
||||||
|
**症状**：`PermissionError: [WinError 32] 另一个程序正在使用此文件`
|
||||||
|
|
||||||
|
**根因**：loguru 在 Windows 上的 50MB 轮转触发 `close() → os.rename()` 竞态。
|
||||||
|
|
||||||
|
**修复**（已默认配置）：`rotation="1 day"` + `retention="7 days"`，避免高并发期轮转。
|
||||||
|
|
||||||
|
如果仍出现：
|
||||||
|
```powershell
|
||||||
|
# 清理残留进程
|
||||||
|
Get-Process python | Where-Object { $_.Path -like "*Python312*" } | Stop-Process -Force
|
||||||
|
```
|
||||||
|
|
||||||
|
### 10.5 残留进程占用文件
|
||||||
|
|
||||||
|
**症状**：杀掉 `arb scan` 后，新进程仍报 PermissionError。
|
||||||
|
|
||||||
|
**排查**：
|
||||||
|
```powershell
|
||||||
|
Get-Process | Where-Object { $_.Name -eq "python" }
|
||||||
|
```
|
||||||
|
|
||||||
|
**清理**：
|
||||||
|
```powershell
|
||||||
|
Get-Process python -ErrorAction SilentlyContinue | Stop-Process -Force
|
||||||
|
```
|
||||||
|
|
||||||
|
### 10.6 仪表板 404 / 端口冲突
|
||||||
|
|
||||||
|
**症状**：浏览器访问 `http://127.0.0.1:8000` 返回 404 或连接拒绝。
|
||||||
|
|
||||||
|
**排查**：
|
||||||
|
```powershell
|
||||||
|
Test-NetConnection -ComputerName 127.0.0.1 -Port 8000
|
||||||
|
Get-NetTCPConnection -LocalPort 8000 -State Listen
|
||||||
|
```
|
||||||
|
|
||||||
|
**修复**：更换端口启动：
|
||||||
|
```bash
|
||||||
|
arb web --port 8888
|
||||||
|
```
|
||||||
|
|
||||||
|
### 10.7 没有任何套利机会
|
||||||
|
|
||||||
|
**症状**：仪表板显示 `recent opportunities` 为空或 net edge bps 全部 < 50。
|
||||||
|
|
||||||
|
**原因**：
|
||||||
|
1. 当前 Polymarket 没有负空间（正常 — 套利机会稀少）
|
||||||
|
2. WS 数据未刷新（检查 `ws subscribed` 日志）
|
||||||
|
3. `ARB_MIN_NET_EDGE_BPS` 设得太高（默认值 50 合理）
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 11. 安全建议
|
||||||
|
|
||||||
|
### 11.1 私钥保护
|
||||||
|
|
||||||
|
- **永远不要把 `.env` 提交到 Git**（已在 `.gitignore` 中）
|
||||||
|
- 实盘私钥使用**专用钱包**，与其他资产隔离
|
||||||
|
- 服务器上 `.env` 文件权限设为 `chmod 600`（Linux）
|
||||||
|
- 考虑使用硬件钱包或多签
|
||||||
|
|
||||||
|
### 11.2 Web 仪表板
|
||||||
|
|
||||||
|
- 默认绑定 `127.0.0.1`，**不要**改为 `0.0.0.0` 后暴露到公网
|
||||||
|
- `kill` / `unkill` 端点**无身份认证**，暴露即等于把钱包控制权交给攻击者
|
||||||
|
- 如果需要远程访问，使用 SSH 隧道：
|
||||||
|
```bash
|
||||||
|
ssh -L 8000:127.0.0.1:8000 user@server
|
||||||
|
```
|
||||||
|
|
||||||
|
### 11.3 依赖管理
|
||||||
|
|
||||||
|
- 锁定关键依赖版本，避免供应链风险：
|
||||||
|
```bash
|
||||||
|
pip install "websockets==14.2" "py-clob-client==0.34.6"
|
||||||
|
```
|
||||||
|
- 定期升级时检查 changelog
|
||||||
|
|
||||||
|
### 11.4 Live 模式额外建议
|
||||||
|
|
||||||
|
- 先用 ≥ $10 的小资金跑 1 周
|
||||||
|
- 每日检查 realized PnL，确认与 paper 结果趋势一致
|
||||||
|
- 设置价格告警（Discord webhook / Telegram bot 等）
|
||||||
|
- 监控 `daily_pnl` 表，日亏损接近 `ARB_DAILY_LOSS_STOP_USD` 时手动 kill
