v4.0.11 switched the fast-submit (`wait_tx_confirmed = false`) result loop
from `wait_for_all_submitted` to `wait_for_first_submitted`. The new
function returns as soon as one SWQOS route's HTTP submit completes and
drains whatever signatures are in `ResultCollector.results` at that
moment — slower routes' signatures arrive after the caller has returned.
This is correct for fire-and-forget low-latency submits, but breaks
callers that do their own on-chain confirmation against a pinned durable
nonce. Only one of the submitted txs can land (nonce is consumed by
whichever lands first), but the caller has no way of knowing in advance
which route it will be. Their post-submit logic feeds every returned
signature to `getSignatureStatuses` to find the landed one — with only
the fastest HTTP responder returned (often not the one that lands), the
landed tx isn't in the polled set.
Adds an opt-in `SwapParams.wait_for_all_submits: bool` (default false,
plumbed through `TradeBuyParams` / `TradeSellParams`). When true and
`wait_tx_confirmed = false`, `execute_parallel` uses
`wait_for_all_submitted` (still in the codebase, was
`#[allow(dead_code)]`) so every submitted signature is returned. Zero
behaviour change for current users.
Sync supported DEX IDLs from bitquery/solana-idl-lib, upgrade protocol builders, and keep trade submission hot paths free of RPC query calls.
Include exact-output coverage, token-account setup fixes for WSOL and stable pairs, and low-latency transaction build improvements.
- Replace compile-time `pumpfun-v2` feature flag with runtime
`TradeConfig::use_pumpfun_v2(bool)` for flexible V1/V2 switching
- Fix BUYBACK_FEE_RECIPIENTS pool: replace wrong addresses (was reusing
standard pool + FEE_CONFIG) with official buyback pool from
FEE_RECIPIENTS.md
- Fix legacy buy/buy_exact_sol_in ix data encoding: use 2-byte
Option<bool> (option tag + value) matching official Pump SDK, 26 bytes
total instead of broken 25
- Add `SwapParams.use_pumpfun_v2` field and wire through TradingClient
buy/sell paths
- V2 instructions read `quote_mint` from `PumpFunParams` (not
BondingCurveAccount which lacks the field)
- Fix `fetch_bonding_curve_account` to use BorshDeserialize instead of
non-existent `decode_from_chain_account_data`
- Update all examples with `use_pumpfun_v2: false` field
- Update README with unified V1/V2 section showing both enabling methods
- Add `mev_protection: bool` to `TradeConfig` and `InfrastructureConfig` (default: false)
- Astralane QUIC: switches to port 9000 (MEV-protected endpoint) when enabled
- BlockRazor HTTP: uses `mode=sandwichMitigation` query param when enabled
- BlockRazor gRPC: uses `mode=sandwichMitigation` when enabled
- Add `SWQOS_ENDPOINTS_ASTRALANE_QUIC_MEV` constants (port 9000) to `constants/swqos.rs`
- Fix `astralane_quic.rs` IP candidates to use the actual port from the address (supports both 7000 and 9000)
- Refactor `TradeConfig` to builder pattern via `TradeConfig::builder()`
- Introduce `TradeConfigBuilder` with all optional fields and clear defaults
- `TradeConfig::new()` kept as a shortcut (calls `builder().build()`) for backward compatibility
- Remove old `with_wsol_ata_config` / `with_check_min_tip` / `with_swqos_cores_from_end` / `with_mev_protection` chain methods
- Update all 16 examples to use `TradeConfig::builder()` with commented-out options so users can discover all available settings at a glance
- Update README.md and README_CN.md code snippets to use builder pattern
🤖 Generated with [Qoder][https://qoder.com]
- Add pumpfun_copy_trading and pumpfun_sniper_trading to workspace members
- Add grpc_recv_us field to all TradeBuyParams/TradeSellParams in examples
- Switch address_lookup and nonce_cache to sol-parser-sdk, use event is_cashback_coin
- Remove invalid rustls call from pumpfun examples for successful build
- All 18 examples pass cargo check --workspace
Made-with: Cursor
In `examples/cli_trading/src/main.rs` line 1093, the print statement uses `{}` but `signature` is now `Vec<Signature>` which doesn't implement `Display`.
Error:
error[E0277]: Vec<Signature> doesn't implement std::fmt::Display
Fix: Change `{}` to `{:?}`
// Before
println!(" ✅ Transaction Signature: {}", signature);
// After
println!(" ✅ Transaction Signature: {:?}", signature);
This was likely missed when updating the sell return type from single Signature to Vec.
Updates all examples to use client.infrastructure.rpc instead of
client.rpc following the shared infrastructure refactor in PR #66.
