Extends the 2026-04-28 program-upgrade prep (commit c25e2ed) to the
remaining trade scripts:
mint_and_buy.py — 18-account buy after bonding-curve-v2.
Tested live with a fresh TEST mint (Solscan
sig 62EZFCKVuxvqmzj...), succeeded.
mint_and_buy_v2.py — 18-account buy. Tested live with a
mayhem-mode TEST2 token (Token-2022 + 5
mayhem accounts), Solscan sig 44SvQSrhmHy...,
succeeded.
pumpswap/manual_buy_pumpswap.py / manual_sell_pumpswap.py
— Adds the 2 new pump-swap accounts (fee
recipient + its quote-mint ATA) gated behind
INCLUDE_BREAKING_FEE_ACCOUNTS = False; flip
to True after 2026-04-28 16:00 UTC.
Pre-existing program-side overflow at
buy.rs:400 (AnchorError 6023) flagged in
a comment — affects current pump-swap
buys, unrelated to this upgrade.
Both pumpswap scripts now also accept TOKEN_MINT via argv[1].

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.

Refreshes the read-only learning examples (Phase A3) against the post
Feb–Apr 2026 IDL changes:
- CreateEvent now has 15 fields (timestamp, 4×u64 reserves, token_program,
is_mayhem_mode, is_cashback_enabled). Listener parsers were truncating
after `creator`; the v2 ones were also reading is_mayhem_mode at the
wrong offset.
- BondingCurve account is now 83 bytes (added is_cashback_coin).
- PumpSwap Pool account is now 245 bytes (added is_cashback_coin) — the
listen_programsubscribe dataSize filter was matching nothing.
- IDL instruction `createV2` was renamed to `create_v2`; the legacy
`create` instruction added a `creator: pubkey` arg in March 2026.
- decode_from_blockSubscribe.py decoder now handles bool, i64, u32, u16,
u8, and the OptionBool defined type (1-byte wire format).
Files touched (all under learning-examples/):
bonding-curve-progress/get_bonding_curve_status.py — V4 struct (cashback)
bonding-curve-progress/poll_bonding_curve_progress.py
decode_from_blockSubscribe.py
decode_from_getAccountInfo.py
decode_from_getTransaction.py
listen-migrations/compare_migration_listeners.py
listen-migrations/listen_programsubscribe.py
listen-new-tokens/compare_listeners.py
listen-new-tokens/listen_blocksubscribe.py
listen-new-tokens/listen_geyser.py
listen-new-tokens/listen_logsubscribe.py
listen-new-tokens/listen_logsubscribe_abc.py
Verified live against mainnet — listeners decode tokens including
mayhem-mode and cashback-enabled curves correctly.

Replace idl/pump_fun_idl.json and idl/pump_fees.json with the latest from
pump-fun/pump-public-docs @ 7de0b95 (2026-04-23). pump_swap_idl.json was
already up to date.
Drops the idl/upstream/ vendor copy added in 7864504 in favor of
overwriting in place — the diff lives in git history. README updated to
point at pump-public-docs as the source of truth.

Snapshot of pump-fun/pump-public-docs @ 7de0b95 (2026-04-23) under

counterparts. Used for local diffing against the IDLs the bot loads from
idl/; not imported at runtime. README links to the new directory.
