- PumpFun buy/sell: append bonding-curve-v2 and random extra fee recipient (writable)
- PumpSwap buy/sell: append pool-v2, protocol fee pubkey, and fee quote mint ATA
- Keep utils helpers and constants aligned with on-chain layout (2026-04 upgrade)
Made-with: Cursor
- Always derive bonding curve and associated bonding vault from mint (avoids stale cached PDAs / wrong pool).
- Use non-default fee_recipient from parser/stream as account #2 without extra authorization filtering (addresses Pump 6000 NotAuthorized when event fee was rejected).
- Rework resolve_creator_vault_for_ix: default-creator cases, phantom default PDA, fee-sharing vault; add unit tests.
- PumpFunParams: respect explicit mayhem_mode from events; fallback creator_vault via get_creator_vault_pda when resolve returns None.
- Remove unused lazy_static tip-cache stub and lazy_static dependency.
Made-with: Cursor
- Add get_fee_sharing_config_pda per @pump-fun/pump-sdk (sharing-config + mint under pump-fees)
- resolve_creator_vault_for_ix now takes mint: accept gRPC creator_vault when it matches either
PDA(creator) or PDA(fee_sharing_config(mint)) for migrated / fee-sharing bonding curves
- Mayhem uses the same Pump buy/sell account layout (IDL); Token-2022 + fee pool differ, not creator_vault seeds
Made-with: Cursor
- Add resolve_creator_vault_for_ix: use gRPC creator_vault only when it matches
PDA(['creator-vault', bonding_curve.creator]); on mismatch use derived PDA to
avoid ConstraintSeeds (2006) from stale/wrong stream vaults
- pump_fun_fee_recipient_meta: only use event fee_recipient if authorized for
is_mayhem_mode (avoids 6000 NotAuthorized when standard AMM fee is used on
Mayhem coins)
- Align PumpFunParams::from_trade/from_dev_trade cached creator_vault with the
same resolution logic
Made-with: Cursor
- Use protocol_params.creator_vault for buy/sell when non-default to avoid
ConstraintSeeds (2006) when gRPC/event creator drifts from on-chain bonding curve
- Preserve event creator_vault in PumpFunParams::from_trade/from_dev_trade instead
of always overwriting with PDA(creator)
- Fee recipient: prefer gRPC fee_recipient; else random from CURRENT_FEE_RECIPIENTS
pool (standard) or MAYHEM pool, matching @pump-fun/pump-sdk fees.ts
- Add cold-path helpers: extend_bonding_curve_account_instruction, PUMP_BONDING_CURVE_MIN_DATA_LEN
Made-with: Cursor
- PumpFunParams::from_trade/from_dev_trade: add mayhem_mode Option; infer Mayhem
via is_mayhem_fee_recipient when None (fixes fee recipient / NotAuthorized 6000
when AMM protocol fee pubkey is used).
- Add is_mayhem_fee_recipient and is_amm_fee_recipient helpers in pumpfun utils.
- Bump solana-* crates to 3.1.12; align tonic/prost; use solana-message for
AddressLookupTableAccount; add solana-system-interface 3.0.
- Update examples and latency script for new PumpFunParams signature.
- SWQoS and transaction builder adjustments for dependency changes.
Made-with: Cursor
- Add BUY_EXACT_SOL_IN_DISCRIMINATOR for PumpFun
- Add BUY_EXACT_QUOTE_IN_DISCRIMINATOR for PumpSwap
- Add use_exact_in_instruction field to SwapParams
- When enabled, uses exact input instructions that spend exactly the
specified SOL/quote amount with slippage applied to output tokens
- Defaults to false for backwards compatibility
