v4.0.11 switched the fast-submit (`wait_tx_confirmed = false`) result loop
from `wait_for_all_submitted` to `wait_for_first_submitted`. The new
function returns as soon as one SWQOS route's HTTP submit completes and
drains whatever signatures are in `ResultCollector.results` at that
moment — slower routes' signatures arrive after the caller has returned.
This is correct for fire-and-forget low-latency submits, but breaks
callers that do their own on-chain confirmation against a pinned durable
nonce. Only one of the submitted txs can land (nonce is consumed by
whichever lands first), but the caller has no way of knowing in advance
which route it will be. Their post-submit logic feeds every returned
signature to `getSignatureStatuses` to find the landed one — with only
the fastest HTTP responder returned (often not the one that lands), the
landed tx isn't in the polled set.
Adds an opt-in `SwapParams.wait_for_all_submits: bool` (default false,
plumbed through `TradeBuyParams` / `TradeSellParams`). When true and
`wait_tx_confirmed = false`, `execute_parallel` uses
`wait_for_all_submitted` (still in the codebase, was
`#[allow(dead_code)]`) so every submitted signature is returned. Zero
behaviour change for current users.
Sync supported DEX IDLs from bitquery/solana-idl-lib, upgrade protocol builders, and keep trade submission hot paths free of RPC query calls.
Include exact-output coverage, token-account setup fixes for WSOL and stable pairs, and low-latency transaction build improvements.
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>
- Append pool-v2 in buy/sell remaining accounts only when pool coin_creator
is not default, matching @pump-fun/pump-swap-sdk. Always appending pool-v2
shifted buyback pubkey/ATA and caused BuybackFeeRecipientNotAuthorized (6053).
- Add coin_creator to PumpSwapParams (filled from decoded Pool / from_trade).
Update pumpswap_trading example to pass pool_data.coin_creator.
- Document buyback fee recipient constants against GlobalConfig.buyback_fee_recipients.
- Extend PumpSwap quote math to include cashback_fee_basis_points in creator-side fees.

- 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
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

- 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
