Refresh the vendored IDLs from pump-fun/pump-public-docs @ 9c82f61 and move all pump.fun trading onto the v2 instruction interface. This is required, not optional: legacy buy/sell cannot trade coins paired against a quote asset other than SOL, and USDC is already whitelisted in the on-chain Global account. Protocol changes absorbed: - buy_v2 (27 accounts) / sell_v2 (26 accounts) replace the legacy instructions. Every account is mandatory and the order is identical for all coins, so the conditional cashback/mayhem account lists are gone. Legacy remains available via PumpFunInstructionBuilder(use_legacy_instructions=True). - BondingCurve is 151 bytes: virtual_sol_reserves -> virtual_quote_reserves, real_sol_reserves -> real_quote_reserves, plus quote_mint at offset 83. Old field names are kept as aliases so existing callers keep working. - v2 instruction data drops the track_volume OptionBool; amounts are in the quote mint's raw units rather than always lamports. - create_v2 carries a non-SOL quote mint as optional remaining accounts 17-19, and CreateEvent gained quote_mint, so extreme_fast_mode can resolve the quote asset without an extra fetch. USDC support: new trade.quote_amounts and filters.allowed_quote_mints config, accepting "sol"/"usdc" aliases or raw mints. Amounts are per-quote-mint because 1 USDC and 1 SOL are not interchangeable. A coin whose quote mint has no configured amount is skipped rather than traded at the wrong size, so SOL-only configs are unaffected. Bug fixes found while verifying: - The logs and blocks listeners set no websocket max_size, so any frame over 1 MiB closed the connection with 1009 and the token in it was lost. Raised to 32 MiB. - PumpSwap priced against the raw quote vault balance, ignoring the new Pool.virtual_quote_reserves (i128 at offset 245; live pools are 301 bytes). Upstream's note that this field is 0 everywhere is out of date: a live pool carries 17.58 SOL against a 148 SOL vault, a 10.15% price error. - The seller read curve state once at confirmed commitment and silently fell back to create-time values, risking a stale creator_vault and ConstraintSeeds. It now retries at processed, matching the buyer. - Account cleanup would burn wrapped SOL when force_burn was set, destroying value that closing the account returns. WSOL is now closed without burning. - The mint scripts treated a landed transaction as a successful one, so a reverted buy printed as success. They now assert the on-chain result. Compute unit limits retuned from mainnet measurements: buy 100k -> 180k, sell 60k -> 120k. Mint-and-buy is no longer atomic, because create_v2 plus buy_v2 exceeds the 1232-byte transaction limit; both mint scripts send two transactions. Adds learning-examples/pump_v2.py as one shared, standalone v2 toolkit for the example scripts, and three verification scripts: an offline layout check against the IDL, a no-funds mainnet simulation, and a live listener matrix that buys, sells and closes the ATA per listener. Verified on mainnet: all four listeners (geyser, logs, blocks, pumpportal) and all eight example scripts completed a real buy, sell and ATA close, each confirmed by reading the transaction result back rather than trusting confirmation alone. The USDC path is verified structurally only; no USDC-paired coin could be found on-chain to exercise it. Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
