Three small ergonomic fixes uncovered while running every learning
example end-to-end:
copytrading/listen_wallet_transactions.py
Was hardcoded to WALLET_TO_TRACK = "...". Now accepts argv[1] so
you can run it without editing the file.
pumpswap/get_pumpswap_pools.py
Same pattern (TOKEN_MINT placeholder) and the underlying
getProgramAccounts call would also time out at the default 30s
on busy mainnet RPCs — bumped both AsyncClient timeouts to 120s.
bonding-curve-progress/get_graduating_tokens.py
Bumped RPC timeout 120s → 240s for the same reason. The threshold
scan over all pump.fun bonding curves still occasionally exceeds
even that on overloaded RPCs (it's a known-heavy query); a smaller
threshold or memcmp-narrowed filter is the proper long-term fix.

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.
