- resolve_creator_vault_for_ix_with_fee_sharing uses non-placeholder ix vault as-is.
- When ix vault missing, fall back to fee_sharing_creator_vault_if_active then PDA(creator).
- Add Pump troubleshooting CN doc; extend PumpFunParams field documentation.
- Bump to v4.0.7.

Adds pumpfun_ix_data / pumpswap_ix_data; exports used by trading::core::params::PumpFunParams.
chore(release): bump version to 4.0.6
Co-authored-by: Cursor <cursoragent@cursor.com>
- 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
- Pump/PumpSwap buy: track_volume OptionBool = Some(true) only when is_cashback_coin, else Some(false)
- PumpSwap sell cashback: use get_user_volume_accumulator_quote_ata(quote_mint) instead of WSOL-only ATA
- Sync idl/pump_amm.json, idl/pump_fees.json from pump-public-docs
Made-with: Cursor
- Change use_exact_sol_amount from bool to Option<bool>
- Default to true (via unwrap_or) for PumpFun and PumpSwap DEXes
- Option is ignored for other DEXes (Raydium, Bonk, Meteora)
- Update all examples to use None (which defaults to true for applicable DEXes)
- Update README documentation

- 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
