Implements the §7.1 policy in code so Token-2022 (pump.fun) tokens are cleanable
when safe:
- @pyre/core: extensions.ts (BLOCKING/FLAGGED/SAFE sets + evaluateTokenExtensions);
classify.ts gates Token-2022 on account+mint extensions; unknown extension or
confidential-transfer/withheld-fee -> UNSUPPORTED; transfer-hook/permanent-
delegate/pausable -> cleanable+flagged. Added malformed-u64-balance guard.
- @pyre/solana: parseTokenAccounts reads account extensions + withheld fee, and
batch-fetches MINT extensions (getMultipleParsedAccounts, chunked).
SECURITY (from audit): mint-fetch failure no longer silently downgrades to
account-level-only (which could hide a mint-level blocking extension). Token-2022
accounts with unverified mints are marked extensionsVerified=false and classified
UNSUPPORTED ("unknown means skip"). Two audit agents: integration SHIP; security
found this CRITICAL -> fixed + tested.
Tests: core 85, solana 8. Live verified: the two pump.fun Token-2022 tokens now
classify INCINERATE_ONLY (were UNSUPPORTED). classic-SPL behavior unchanged.

Solana transaction helpers for PYRE.
Purpose
Token-account reading and unsigned transaction construction for the burner flow. Per §13 its responsibilities are:
- Token-account parsing.
- Close-account transaction builder.
- Burn transaction builder.
- Simulation helpers.
- Transaction decoder (for preview matching).
Trust rules (load-bearing)
- PYRE never holds private keys — this package builds unsigned transactions; signing happens client-side in the user's wallet.
- Recovered ATA rent defaults to the user's own wallet.
- Always simulate, then decode and match against the user-facing preview before requesting a signature.
- Classic SPL only in the MVP. Skip Token-2022, NFTs, and unsupported layouts.
Status
Stubs only. Every exported function throws Error("not implemented").
TODO
- Implement
parseTokenAccounts,buildCloseEmptyAccountsTx,buildBurnTx,simulateTransaction, anddecodeTransaction. - Wire classification through
@pyre/core.
