- 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.

Changes to src/utils/calc/common.rs:
- Add MAX_SLIPPAGE_BASIS_POINTS constant (9999 = 99.99%)
- Clamp basis_points in calculate_with_slippage_buy to prevent amount doubling
Changes to src/instruction/pumpswap.rs:
- Fix WSOL wrap amount calculation for exact vs non-exact input modes
- Use input_amount for exact mode, sol_amount for non-exact mode

DataSize(252) filter rejects Token2022 PumpSwap pools which are 643 bytes.
This causes find_by_mint to miss pools that already exist on-chain, leading
to unnecessary 45s+ wait loops during migration detection.
Remove the DataSize filter from find_by_base_mint and find_by_quote_mint —
the Memcmp filter on program-owned accounts is specific enough.
Also add diagnostic logging on find_by_mint failure for debugging.

- 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

- 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

Fixed a critical bug in find_by_base_mint and find_by_quote_mint functions
where pool data decoding failed because the 8-byte discriminator was not
being skipped. This caused all PumpSwapParams::from_mint_by_rpc calls to
fail with "No valid pool decoded" error.
Changes:
- Modified find_by_base_mint to skip discriminator: pool_decode(&acc.data[8..])
- Modified find_by_quote_mint to skip discriminator: pool_decode(&acc.data[8..])
- Added data length check to prevent out-of-bounds access
- Aligned with fetch_pool function which correctly uses &account.data[8..]
