PumpSwap (manual_buy_pumpswap.py / manual_sell_pumpswap.py)
- Real on-chain pump-swap buys use 24 accounts; the IDL is incomplete
(lists 23). Missing 24th account is pool-v2 PDA, derived from seed
["pool-v2", base_mint] under the pump-amm program.
- Without it, pump-amm throws AnchorError 6023 (Overflow) at buy.rs:400/414
after the trade transfers complete (the source of the earlier "pre-existing
overflow" — was actually a missing account, not a math bug).
- find_pool_v2(base_mint) added; appended to both buy and sell account lists
after fee_program. The April-28 breaking-fee accounts (still gated behind
INCLUDE_BREAKING_FEE_ACCOUNTS) come after pool-v2 — matching the doc's
"All accounts till bonding-curve-v2 and pool-v2 remain the same."
- AsyncClient timeout bumped to 120s so the heavy getProgramAccounts pool
lookup doesn't time out on slower RPC paths.
- Live-verified on mainnet with 9PwadsGz...pump:
buy 2xgdJJsDMzoMyxJzrCATKwGfpX7M... err=None (24 accounts)
sell 4vdBkGpCMQYEWncj5k1suGzKPUMQ... err=None (24 accounts)
manual_buy_geyser.py
- Fixes IndexError when create tx references ALT-loaded keys
(matches the same fix applied to manual_buy.py).
- Re-enables the 15s sleep + on-chain price/fee_recipient lookup that
were commented out for testing — needed for buys on real pools.

(18-account buy, err=None) on Token-2022 cashback-enabled INSIDER mint.

pump.fun program upgrade scheduled for 2026-04-28 16:00 UTC adds one new
mutable account (one of 8 fee recipients) at the end of buy/sell ixs,
after bonding-curve-v2. The new format is already accepted on mainnet
ahead of the cutover, so applying now keeps scripts working on both
sides of the upgrade.
Doc: github.com/pump-fun/pump-public-docs/blob/main/docs/BREAKING_FEE_RECIPIENT.md
Per file:
manual_buy.py — 18-account buy. Also fixes a pre-existing
listener crash on Address-Lookup-Table create
txs (skips them) and adds bool/OptionBool
handling to decode_create_instruction so
create_v2 doesn't raise on its trailing args.
manual_buy_cu_optimized.py — 18-account buy. Bumps the CU-optimization
account-data limit to 16MB (tested) — older
values trigger MaxLoadedAccountsDataSizeExceeded
on Token-2022/cashback coins. Same listener
ALT-skip and decoder bool fixes.
manual_buy_geyser.py — 18-account buy. Re-enables price calculation
and mayhem-mode-aware fee_recipient detection
(was scaffolded out for testing).
manual_sell.py — 16-account non-cashback / 17-account cashback
sell. Reads is_cashback_coin from BC byte 82
and inserts user_volume_accumulator before
bonding-curve-v2 when needed. TOKEN_MINT now
accepts argv[1] override.
Live-verified on mainnet:
buy manual_buy.py 3AVnLC3sdBD598cs3... + 3bWU9bB8U9aemA2BFhS2...
buy manual_buy_cu_optimized 2PfH5rHw62o3KkQ3N4z8...
sell manual_sell.py 3E7dyPBPBRe95BtPQXmb... + 5L4wWSzPV36m6XqXAswB...
All four show the expected 18 (buy) / 16 (sell non-cashback) account count
with one of the 8 BREAKING_FEE_RECIPIENTS as the trailing mutable account.

* fix(examples): add bonding_curve_v2 remaining account to learning examples
Add the required bonding_curve_v2 PDA as a remaining account to buy/sell
instructions in manual_buy, manual_sell, mint_and_buy, and mint_and_buy_v2
learning examples, matching the pump.fun program upgrade.
