ae937fd477 fix(cookbook,tools): fail on an unreadable value instead of substituting a default (#225)
* fix(cookbook,tools): read GEYSER_AUTH_TYPE and reject an unknown scheme

Four Geyser clients advertised the variable and ignored it, sending Basic for
anything that was not exactly "x-token". Validate against {x-token, basic}.

* fix(cookbook): detect blockSubscribe creations from logs alone

The envelope fallback cannot see a create reached by CPI, so it covered a
subset of the log route. Envelope decoding stays in the decode/ script.
Also skip meta.err: logs emitted before a failure are kept, and that mint
does not exist.

* fix(cookbook): raise when the graduation baseline cannot be read

The watchers fell back to a hardcoded 793,100,000 and still printed it as
"(from Global)". Every progress figure is measured against that baseline.

* fix(cookbook): report an unsent create flag as unknown, not false

Truncated create_v2 args and legacy create were filled in as False, reading
as a coin the program said is not in mayhem mode. Leave them out, print N/A.

* fix(tools): build Geyser credentials before the reconnect loop

The loop catches every exception and sleeps, so an unusable auth type
reconnected forever instead of reporting a misconfiguration.

* fix(cookbook): treat a short Global buffer as an unreadable baseline

The guard only caught a missing account, so a short read raised struct.error
past the documented ValueError.

* fix(tools): surface a listener's exception instead of an idle market

A listener that raised on connect returned nothing, exactly like a quiet
market, in the harness whose job is to certify listeners. Take the listener
list from the factory too, so one added there is not silently skipped.

* fix(tools): simulate the transaction the bot built

The hook rebuilt the transaction itself and dropped the account data size
limit, so the simulation was more permissive than the send. Hook the RPC
client instead, build the client before detection so its blockhash cache is
warm, and report the compute budget read back off the wire.

A listener that raised on connect also read as a quiet market here.

* fix(tools): skip failed migrations on err, not on the word "Error"

The notification carries err beside the logs. Scanning the text dropped a
migration whose logs merely said "Error" and kept ones that truly failed.

* fix(cookbook): refuse a letsbonk buy that accepts any output

The only one of the four without the guard. Near graduation the floor
division reaches zero, and the buy submits with no slippage protection.

* fix(cookbook): require the pool's own platform_config

The fallback was a partner-specific address that reverts with
ConstraintAddress (2012). A pool that omits it cannot be traded.

* fix(cookbook): raise when curve data ends before a flag

is_mayhem_mode picks the fee recipient for a buy, and the wrong one reverts
with NotAuthorized (6000), so defaulting it only moves the failure.

* fix(cookbook): trade the coin's own PumpSwap pool, not an arbitrary one

Anyone can open a pool against any mint and getProgramAccounts has no defined
order, so [0] was a stranger's pool. Select on coin_creator, which migration
copies from the bonding curve and nothing else sets, and refuse rather than
guess when there is no single match. --pool trades a specific one.

b04a375506 fix(cookbook): resolve quote-mint decimals instead of assuming 9 (#222)
QuoteControl admits mints from 4 to 12 decimals, so the default was wrong
for most quote assets and silently so. Parsers return raw quote reserves;
callers scale off the mint account.

Same class elsewhere: pumpswap refuses non-SOL-quoted pools instead of
capping in the wrong unit, letsbonk exact_out/exact_in scale by
base_decimals, wallet_trades decodes through to quote_mint (fixing an
ix_name offset that left later fields three bytes short), balances read at
confirmed, cleanup_accounts takes a required mint.

Verified on mainnet with real funds; wallet left holding SOL only.

ebbfa9f124 chore(deps): upgrade to solders 0.29 / solana 0.40 and bring the rest of the dependencies current (#217)
* chore(deps): upgrade solders to 0.29 and solana to 0.40 in cookbook and tools

solana 0.40 moves TxOpts (now TxOptsModel), MemcmpOpts and TokenAccountOpts
from solana.rpc.types to solana.rpc.core, and spl.token's *Params dataclasses
to spl.token.models as pydantic models — validated and keyword-only. Three
call sites only failed against mainnet: MemcmpOpts.bytes now takes a base58
str, SyncNativeParams was built positionally, and confirm_transaction was
passed a bare "confirmed".

Also moves every cookbook and tools send path off the legacy Transaction onto
VersionedTransaction + MessageV0, and teaches the getTransaction decoder the
json and base64 encodings alongside jsonParsed — the base64 v1 fixture needs
solders 0.29 to deserialize at all.

src/ is untouched and still on the old imports; the offline suite is 3/19
until that lands.

Verified on mainnet: a 0.003 SOL buy_v2/sell_v2 round trip confirmed and the
wallet returned to SOL only, all six listeners and every read-only script run
live, five trade paths simulated with error=None.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* chore(deps): move the bot onto solders 0.29 and solana 0.40

Same three API moves as the cookbook commit, now in src: TxOpts is
TxOptsModel in solana.rpc.core, and spl.token's BurnParams/CloseAccountParams
come from spl.token.models. build_and_send_transaction builds a
VersionedTransaction from MessageV0 with no lookup tables, so the bot no
longer sends a legacy transaction anywhere.

verify_transaction_v1 proved the log route by stripping the logs and expecting
nothing back, which only held while solders could not read a v1 envelope. On
0.29 it can, so the check is inverted: make the envelope unreadable, keep the
logs, and the create must still arrive. A second check pins the envelope
fallback, so a decode regression is reported rather than silently absorbed by
the log route.

Offline: 19/19. Live on mainnet, funds returned:
- tools/simulate_bot_buy_path: zero-RPC buy path, err=None, 107,015 CU
- tools/simulate_v2_trades: buy_v2 95,573 CU, buy+sell 174,190 — both inside
  the existing 180k/120k limits, so no retune
- tools/live_v2_round_trip: buy_v2 + sell_v2 both landed
- tools/live_listener_matrix: all four listeners detected; logs and pumpportal
  ran full round trips; geyser and blocks both drew a coin on an unconfigured
  quote mint and correctly refused to size a buy. Every ATA closed.

* chore(deps): bring the rest of the dependencies to current

Every remaining dependency is now at its latest release, with the floors
raised to the versions actually tested rather than the oldest that resolves:

  grpcio        1.73.1 -> 1.84.0    grpcio-tools 1.73.1 -> 1.84.0
  protobuf      6.33.5 -> 7.36.2    uvloop       0.21.0 -> 0.22.1
  pyyaml        6.0.2  -> 6.0.3     python-dotenv 1.2.2 -> 1.2.3
  construct     2.10.70 (floor)     websockets   17.1 (floor)
  ruff          0.12.4 -> 0.16.8

aiohttp and base58 were already current. winloop is left at its old floor:
it is Windows-only and cannot be installed, let alone tested, here.

protobuf 7 arrives with grpcio-tools 1.84 and is the only major. The
committed geyser stubs are gencode 6.31.1 and still pass
ValidateProtobufRuntimeVersion against it; they are not regenerated, because
the committed files import each other absolutely and protoc does not emit
that, so the output would need rewriting. Noted in CLAUDE.md with the
verification date.

ruff 0.16 needs no config change. The repo-wide baseline moves 1680 -> 1713
because the rules moved, not the code; CLAUDE.md carries the new figure so it
is not misread as a regression.

Verified per dependency, not just in aggregate: all four bot configs load
under the new pyyaml/dotenv; the logs, blocks and pumpportal listeners run
under the uvloop policy bot_runner installs; both geyser paths (token
listener and the account-filtered graduation watcher) run under grpcio 1.84 /
protobuf 7. Offline 19/19, including verify_listener_cancellation for
websockets. One more live buy_v2/sell_v2 round trip on the final set, both
landed, ATA closed.

* fix(utils): redact RPC credentials from every log record

The provider endpoints carry their API key in the URL and the HTTP clients log
a full request URL at INFO, so anything that raises the root logger to INFO
prints the key. tools/cleanup_accounts.py did, four times, in a terminal.

It was already silencing httpx and httpcore by name. That stopped working the
moment solana-py 0.40 switched to httpx2: the rename took the guard with it
and nothing said so. Naming the clients is now a convenience on top of the
real control — install_secret_redaction masks the value itself, at log-record
creation, whichever logger emits it.

It redacts the *rendered* message rather than record.msg plus the string
arguments. The first version of this did the latter and still leaked: httpx2
passes its URL as a URL object, so the type check skipped the only argument
carrying the key. Confirmed by forcing httpx2 back to INFO and watching the
key print anyway. The host is kept, so a log line still says which provider
answered.

Installed from get_logger, from both logging.basicConfig sites, and from
setup_file_logging before it attaches the handler — logs/ outlives a terminal.

verify_no_rpc_credentials_logged covers all of it, including the non-str
argument. Checked against the defeated version first: it fails there and
passes here. Suite is 20/20.

* docs(agents): make a real bot run the verification, not the simulations

The ground rule said never to run a bot with real funds, which points at the
tools/ harnesses instead. Those call the buyer, seller and listeners directly:
they skip bot_runner, config loading, the trader loop, the exit strategy and
cleanup, so passing there says nothing about the paths only a full run reaches.
Verification is a real run, with explicit approval for that session, covering
every mode the change touches and ending with the wallet holding SOL only.

Also records why a run can look clean when nothing happened: pump_bot runs every
bots/*.yaml, three of the four committed configs ship enabled: false, and with
all of them disabled it prints nothing and exits 0. The log file is the tell.

* docs(utils): keep the redaction comment provider-neutral

The parameter list is what matters, not which provider uses which spelling.

41b971147a refactor(cookbook): restructure learning-examples, add missing actions, fix quote decimals (#216)
* refactor(tests): move the regression verifiers into tests/regression

verify_*.py are not standalone examples: each imports src/, stubs the RPC
client, and asserts one previously fixed bug stays fixed. Their checks are
unchanged; PROJECT_ROOT, the usage lines and the bonk fixture lookup are
adjusted for the new depth. run_all.py runs the set and reports failures.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* chore(tools): move the dev harness and listener benchmarks into tools/

simulate_*, live_*, both compare_* scripts and the account cleanup import
src/ and several spend real funds — they exercise the bot rather than teach
anything. compare_listeners.py reaches the repo root one level higher than
before; nothing else changes.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* refactor(cookbook): reorganise learning-examples into cookbook/

The directory is a reference collection — one runnable script per action — but
nothing said so: no index, scripts grouped by the transport they happened to
use, fixtures loose at the root.

Now grouped by platform, then by what you are doing:
pumpfun/{listen,read,trade,graduation,decode}, pumpswap, letsbonk, legacy.
Fixtures sit beside the script that reads them, manual_sell.py becomes
sell_token.py, and the legacy create example moves to legacy/ and says why.
pump_v2.py and tx_status.py stay at the cookbook root as the only two shared
helpers; subdirectories add that root to sys.path before importing them.
cookbook/README.md indexes every script and marks the ones that spend funds.

Also fixes create_v2's account list: the five mayhem accounts are mandatory
whatever is_mayhem_mode says, so mint_and_buy_v2.py could never have worked
with mayhem off. 11 accounts fails AnchorError 3005 (AccountNotEnoughKeys) on
sol_vault, 16 succeeds with the argument either way — simulateTransaction
against mainnet. Seven scripts gain a module docstring they were missing.

* feat(cookbook): add buy, create, balance and status examples

  buy_token.py <MINT>        buy_v2 against one coin; --dry-run simulates
  create_token.py            create_v2 on its own
  get_balances.py            SOL and tokens across both token programs
  check_tx_status.py <SIG>   success, reverted, or not visible yet

Buying previously meant manual_buy.py, which waits for the next coin created
anywhere before it trades — there was no way to buy a coin you already know.
Creating one meant bundling a buy with it, and the transaction-status helper
was a library with no entry point.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* refactor(cookbook): move pump_v2 next to the scripts that use it

pump_v2.py holds the buy_v2/sell_v2 account layouts, and only the pump.fun
trade scripts import it — it sat at the cookbook root because tx_status.py
does, not because anything outside pumpfun/trade/ needed it. The five callers
now pick it up as a plain sibling; legacy/ and the layout verifier reach into
that directory. tx_status.py stays at the root, where all four platforms use it.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* refactor(cookbook): name every script protocol_verb_noun_variant

manual_buy.py did not just buy — it waited for the next coin created anywhere,
then bought, so the verb was wrong. Protocol was encoded three different ways:
directory, suffix, or not at all. And three scripts sat under pumpfun/ that have
nothing to do with pump.fun.

Filenames are now <protocol>_<verb>_<noun>[_<variant>].py, so a basename says
which chain, what it does and which instruction version without opening it:

  manual_buy.py            -> pumpfun_snipe_token_blocksubscribe.py
  manual_buy_geyser.py     -> pumpfun_snipe_token_geyser.py
  buy_token.py             -> pumpfun_buy_token_v2.py
  mint_and_buy_v2.py       -> pumpfun_create_and_buy_token_v2.py
  manual_buy_pumpswap.py   -> pumpswap_buy_token.py
  manual_buy_exact_in.py   -> letsbonk_buy_token_exact_in.py
  legacy/mint_and_buy.py   -> legacy/pumpfun_create_and_buy_token_v1.py

The sniper was named for logsSubscribe in an earlier draft; it sends
blockSubscribe, and the name now says so.

Balances, transaction status and the Anchor discriminator calculator are not
pump.fun-specific and move to a new cookbook/solana/. The two non-runnable
helpers take no verb — pump_v2.py becomes pumpfun_instructions_v2.py beside its
callers, tx_status.py becomes solana_transaction_status.py in solana/. Both are
imported under a short alias so the 106 call sites stay readable.

* fix(cookbook): resolve a coin's quote mint before pricing it

quote_units() defaulted to 9 decimals for an unresolved mint, and every trade
script called it before resolve_quote_token_program() warmed the decimals
cache. pump.fun's QuoteControl registry admits mints at 6, 8 and 9 decimals —
79 of the 170 admitted are tokenized equities, 8 decimals for xStocks and 6 for
Backpack Securities — so those coins were sized against the wrong power of ten.

The error compounds rather than cancels: price_per_token() divides by the same
wrong unit, so the price reads low by the factor, the token amount comes out
high by it, and the inflated cap authorises the overspend instead of catching
it. 10x on an xStock pair, 1000x on a Backpack one.

This is not hypothetical. A 75s sample of live curve updates on 2026-09-22
caught 8 stock-paired curves out of 124 — IONQ across 5 of them, plus QUBT,
PLTRx and COPX.

quote_units() now raises for an unresolved mint instead of guessing, the four
trade paths resolve before they price, and pumpfun_read_price.py reads decimals
from chain rather than from a two-entry table. The geyser sniper never resolved
at all: it also passed SPL Token as the quote token program, which fails the
account constraints for any Token-2022 quote, and created no quote ATA.

verify_quote_decimals_resolved.py checks the fail-closed contract, that
resolution costs no extra RPC call, and that no function prices before it
resolves — confirmed to fail when the ordering is put back.

* feat(cookbook): read the quote-mint registry and Token-2022 mint state

Two reads that were unreachable without knowing an undocumented PDA seed.

pumpfun_read_quote_mints.py decodes QuoteControl (PDA ["quote-control"]), the
second quote-mint registry added in the 2026-09-15 upgrade. Reading only
Global.whitelisted_quote_mints under-reports: a coin can be paired with a mint
Global has never heard of. 170 admitted today, 79 of them tokenized equities,
each with the initial virtual quote reserves that set a new curve's opening
price. --stocks narrows to the equities, identified by the Token-2022 extension
set create_v2 requires of them rather than by a name lookup.

solana_read_token2022_mint.py reads the extensions that change what a balance
means: scaled UI amount, pausable, permanent delegate, transfer hook, default
account state. It exists mainly for one trap — the RPC returns both `multiplier`
and `newMultiplier` with an effective timestamp, and once that timestamp passes
the field named `multiplier` is the stale one. On AAPLx it passed on 2026-08-08,
so the obvious field has been wrong for six weeks. This compares against the
clock and says which is in force.

* feat(cookbook): add the exact-quote-in buy

buy_exact_quote_in_v2 was uncovered. It is the mirror of buy_v2 — buy_v2 fixes
the tokens received and caps the spend, this fixes the spend and floors the
tokens — and it takes the same 27 accounts in the same order, so it reuses
build_v2_accounts and differs only in discriminator and arguments.

Worth having because pinning the spend is the natural direction once a coin is
priced in something other than SOL: "spend exactly one AAPLx" is something you
can mean, where a token count is a number derived from a price that moved while
you derived it.

Verified by simulateTransaction against a live COPX-paired coin: the program
executes the full buy and stops at TransferChecked with insufficient funds,
which is as far as a wallet holding none of the quote asset can go.

Claude-Session: https://claude.ai/code/session_01EZ5HdjTadNUad8i6xis3TR

* feat(cookbook): add the exact-SOL-in buy

buy_exact_sol_in was uncovered. SOL only — it pre-dates non-SOL quote assets and
carries no quote accounts, so the script checks the curve and points at the
exact-quote version for anything else rather than failing obscurely.

Its account list is the reason to have it. The IDL lists 16; the program needs
18, the extras being the bonding-curve-v2 PDA and a buyback fee recipient.
Determined by simulation rather than assumed: 16 accounts fails AnchorError 6062
(BuybackFeeRecipientMissing), 18 simulates clean at 96k CU. The v2 instructions
are complete in the IDL and this family is not, which is worth a newcomer
knowing before they trust the file.

The docstring carries the IDL's own fee arithmetic, since fees come out of the
amount you name rather than on top of it, and the printed estimate ignores that
split while min_tokens_out is what the program enforces.

* feat(cookbook): add the creator-fee and cashback payouts

Two payout paths that had no script. Both take no arguments and, per the IDL,
no signer — the funds can only reach the wallet they already belong to, so
either can be run for anyone, which --creator and --user expose.

collect_creator_fee_v2 sweeps a creator vault. The vault is per creator and per
quote asset, so a creator whose coins are priced in several assets collects each
separately; --quote picks which.

claim_cashback_v2 pays out an accrued cashback balance. create_v2 has rejected
new cashback coins since 2026-09-15 (error 6082), but coins minted before that
keep accruing and stay claimable, which is why the cashback handling elsewhere
in this repo is not dead code.

Both verified by simulateTransaction against mainnet: 10 accounts each, 8 data
bytes, no error.

Also repairs two cookbook README rows that the earlier rename mangled —
pumpswap_buy_token.py had been rewritten to pumpswap_pumpfun_buy_token_v2.py
because its name contains the string that rename matched on.

* refactor(cookbook): take every script's input on the command line

A reference collection only works if you can run a script against your own coin
without editing it. Several carried the coin as a module-level constant instead:

    TOKEN_MINT = Pubkey.from_string(sys.argv[1] if len(sys.argv) > 1 else "...")

which reads as optional but raises at import, so running the script the way its
own usage line described it died on ValueError: Invalid Base58 string before
printing anything. Nine scripts did this. Four more took their amount and
slippage from environment variables that no usage line mentioned.

Every script now builds an ArgumentParser in main(): required values are
positionals, tunables are --options, and the literals live in DEFAULT_* constants
that supply the defaults. --help works on all 32 that take input; the seven
listeners take none and are exempt. The decode scripts keep defaulting to the
fixture beside them, so they still run bare.

Behaviour is unchanged. create_and_buy's mayhem flag defaulted to on, so it takes
--mayhem/--no-mayhem via BooleanOptionalAction rather than a store_true that
would have silently flipped it off.

Two fixes found while threading the values through: the wallet listener read a
global `wallet` from four functions that no longer had one, and find_pool raised
IndexError on a coin that has not graduated instead of saying so.

verify_cookbook_arguments.py enforces the shape — no module-level sys.argv, no
placeholder values, argparse wherever there is input, and every default a usable
value. Confirmed to fail when the old pattern is put back.

* fix(docs): replace three dead links and check the rest

The Anchor discriminator citation in anchor_calculate_discriminator.py pointed
at book.anchor-lang.com/anchor_bts/discriminator.html, which Anchor removed when
it restructured its docs. Two links in the README had also moved:
docs.chainstack.com/quickstart/ and docs.chainstack.com/docs/trader-nodes.

  book.anchor-lang.com/anchor_bts/discriminator.html
    -> www.anchor-lang.com/docs/basics/idl          (has a Discriminators section)
  docs.chainstack.com/quickstart/
    -> docs.chainstack.com/reference/blockchain-apis
  docs.chainstack.com/docs/trader-nodes
    -> docs.chainstack.com/docs/solana-trader-nodes

All 28 real URLs in the repo now return 200, checked by fetching each one.

verify_documentation_links.py keeps them honest: offline it asserts every URL is
https and that none of the four dead endpoints has come back, and --live fetches
each and fails on 4xx/5xx. It skips the unroutable hosts the offline verifiers
point stub clients at, and example.com, which RFC 2606 reserves for exactly the
placeholder metadata URI a test coin is created with.

The discriminator script also still asked you to edit a constant, which the
argument rule had just outlawed, so it takes the name on the command line and
prints the u64, the byte list and the hex. Cross-checks against the constants in
pumpfun_instructions_v2.py: global:buy_v2 gives [184, 23, 238, 97, 103, 197,
211, 61], which is BUY_V2_DISCRIMINATOR.

* fix(cookbook,tools): detect coins via logs so v1 transactions are not skipped

Solana transaction v1 has been live since 2026-09-15 and solders cannot
deserialize one until 0.29. Three scripts detected coins by deserializing the
transaction envelope, so each went blind to v1:

  cookbook/pumpfun/listen/pumpfun_listen_tokens_blocksubscribe.py
      30,080 "skipping a v1 transaction" lines in 150s
  tools/compare_listeners.py
      601 "Failed to process transaction: io error: unexpected end of file"
      in 100s, which its own comment read as a transport difference
  cookbook/pumpfun/trade/pumpfun_snipe_token_blocksubscribe.py
      skipped v1 silently, so a coin created in one was never sniped

All three now route on meta.logMessages, which the RPC has already decoded and
which reads the same for every version. The blocks example keeps the envelope
decode as a genuine fallback for providers that return blocks without logs; the
sniper derives the associated bonding curve from the mint and curve instead of
reading the instruction's account list, verified against
pumpfun_derive_curve_addresses.py on a live coin.

Measured live after the change: the blocks example decoded 88 v0, 6 v1 and 4
legacy creates with zero skips and zero errors, and compare_listeners' block
lane now appears alongside logs and geyser for the same coins.

Upgrading solders was tried first and reverted. 0.29 does decode v1 — 0.26,
0.27.1 and 0.28 all raise "io error: unexpected end of file" on the committed
fixture — but it requires solana>=0.40, which moved TxOpts, MemcmpOpts and
TokenAccountOpts out of solana.rpc.types. 22 files import them and 16 of 19
verifiers failed on the import alone, so that is a migration of its own.

verify_transaction_v1.py gains a check that no cookbook or tools listener
detects by opening the envelope. It found the sniper, which this had missed.

* fix(cookbook): label the transaction version and restore the lost fields

The blocks listener printed "Found CreateEvent in a 0 transaction", which reads
as a count rather than what it is — Solana's transaction version. It now prints
v0, v1 or legacy.

Routing detection through the CreateEvent also dropped two fields the
instruction path used to fill, so every detection showed "Token Standard: N/A"
and no Associated BC. Both come from the event's token_program: the standard is
that program, and the associated bonding curve is an ordinary ATA of the curve
under it. Verified against pumpfun_derive_curve_addresses.py on a live coin —
curve E94izXvHd7dd... derives to He94dArnuprt..., matching what the listener
now prints.
