- 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

calculate_with_slippage_sell previously fell through to the branch that
returned 1 when amount <= basis_points/10_000, which is true for amount=0
and typical bps values—yielding a bogus minimum of 1. Short-circuit on
zero input so sell quotes stay correct.

- 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.

fix(swqos): extend parallel-submit wait/grace windows for late HTTP responses
- Scale primary submit timeout with configured channel count (clamped 3–5s)
- After primary expiry, optionally poll longer so slow providers still land before drain
- Short settle sleeps to reduce counter vs TaskResult races and dropped signatures when
wait_transaction_confirmed is false

- 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)

- Enable quinn feature runtime-tokio so QUIC clients (Speedlanding/Soyas) initialize instead of failing with "no async runtime found".
- Align Speedlanding with the official client: use solana_tls_utils new_dummy_x509_certificate and SkipServerVerification; use fixed TLS SNI "speed-landing" (not the PoP hostname).
- Raise per-SWQoS init timeout to 15s; always log init failures/timeouts; if every SWQoS client fails, fall back to Default RPC and print active channel labels.
- Improve SWQoS submission visibility (Default RPC path and related logging); adjust Soyas TLS credential handling where applicable.

- Pass token_a/token_b program based on swap direction (is_a_in) when
creating the output mint ATA in buy flow, matching ATA address derivation
for SPL Token vs Token-2022 mints.
- Resolve token_a_program and token_b_program from on-chain mint account
owners in MeteoraDammV2Params::from_pool_address_by_rpc instead of
hardcoding the classic SPL Token program.
Fixes incorrect ATA creation for Token-2022 output mints (issue #99).

- Extend SWQOS regional constants to 10 entries (Dublin, Singapore, Default)
so indices match SwqosRegion 0..9 everywhere
- Document geographic nearest-fill among published PoPs; call out Default and
single-PoP provider constraints in comments
- Fix Node1 QUIC Default endpoint to match HTTP; tune ZeroSlot/Blox/Speedlanding
regional mappings where a closer published PoP exists
- Add unit tests for table length and Astralane/Node1 cross-table consistency
- Update SwqosRegion rustdoc, README, and trading_client example accordingly
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.

- Astralane QUIC: switches to port 9000 (MEV-protected endpoint) when enabled
- BlockRazor HTTP: uses `mode=sandwichMitigation` query param when enabled
- BlockRazor gRPC: uses `mode=sandwichMitigation` when enabled
- Add `SWQOS_ENDPOINTS_ASTRALANE_QUIC_MEV` constants (port 9000) to `constants/swqos.rs`
- Fix `astralane_quic.rs` IP candidates to use the actual port from the address (supports both 7000 and 9000)

- Introduce `TradeConfigBuilder` with all optional fields and clear defaults
- `TradeConfig::new()` kept as a shortcut (calls `builder().build()`) for backward compatibility
- Remove old `with_wsol_ata_config` / `with_check_min_tip` / `with_swqos_cores_from_end` / `with_mev_protection` chain methods
- Update all 16 examples to use `TradeConfig::builder()` with commented-out options so users can discover all available settings at a glance
- Update README.md and README_CN.md code snippets to use builder pattern

- Store gRPC client as Arc<ArcSwap<BlockRazorGrpcClient>> so BlockRazorBackend
can derive Clone (ArcSwap does not implement Clone).
- Cloning the outer Arc gives owned handles for tokio::spawn in start_ping_task,
fixing E0521 (borrowed self escaping to 'static future).

Implement lock-free reconnection mechanism using ArcSwap to maintain high
performance for transaction sending while providing automatic recovery
from connection failures.
Key improvements:
- Add automatic reconnection with exponential backoff (1s -> 60s max)
- Use ArcSwap for lock-free atomic reference swapping
- Zero overhead for send_transaction path: only atomic load operation
- Background health check every 30s triggers reconnection on failure
- Reconnection success resets backoff delay to 1s
This ensures transaction sending remains fast (no lock contention) while
providing automatic recovery from network issues or server restarts.
Inspired by the proven reconnection pattern in sol-parser-sdk.
