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.
- 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.

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

- 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.

- 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
- 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
Bump crate/docs version to 4.0.2 and add release notes covering IPv4/IPv6 address-family handling, direct-IP candidate preference, and endpoint failover rotation for more stable low-latency QUIC submission.

## Changes since v4.0.0
### Bug Fixes
- Fixed BlockRazor gRPC endpoints to use correct gRPC service URLs
- Set gRPC as the default transport layer for BlockRazor with HTTP fallback
This release improves the reliability and performance of BlockRazor integration by prioritizing gRPC communication while maintaining HTTP fallback compatibility.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Major changes:
- Switch BlockRazor default transport from gRPC to HTTP to avoid FRAME_SIZE_ERROR
- gRPC mode still available via explicit SwqosTransport configuration
- Fix ZeroSlot Binary-Tx JSON-RPC 2.0 response parsing
- Properly handle success responses with "result" field
- Properly handle error responses with "error" field containing code and message
- Update version to 4.0.0
- Update README files to reflect new version
Technical details:
- BlockRazor: HTTP mode is now the default (SwqosTransport::Http or None)
- ZeroSlot: Parse JSON-RPC 2.0 format responses instead of plain text
- Proto code: Pre-generated gRPC code for BlockRazor (no protoc required)

- Add TradeConfig::with_swqos_cores_from_end(bool) to use last N CPU cores for SWQOS, reducing contention with main thread and default tokio workers.
- Add recommended_sender_thread_core_indices(swqos_count) to get the same last-N core indices for with_dedicated_sender_threads (recommended combo for lower latency).
- Document core affinity and latency in async_executor and with_dedicated_sender_threads.

- Bump version to 3.6.4 in Cargo.toml
- Update version references in README.md and README_CN.md
- Add RELEASE_v3.6.4.md with English release notes
- All workspace examples verified to compile (cargo build --workspace)
- Remove RELEASE_v3.6.3.md and docs/ASYNC_EXECUTOR_REVIEW.md
- Minor updates in types, lib, transaction_builder, async_executor, executor, params
Made-with: Cursor
- Add pumpfun_copy_trading and pumpfun_sniper_trading to workspace members
- Add grpc_recv_us field to all TradeBuyParams/TradeSellParams in examples
- Switch address_lookup and nonce_cache to sol-parser-sdk, use event is_cashback_coin
- Remove invalid rustls call from pumpfun examples for successful build
- All 18 examples pass cargo check --workspace
Made-with: Cursor
- Bump version to 3.5.4; update README and README_CN
- Astralane: irisb binary API (no Base64), POST /irisb with query api-key&method; constants use /irisb endpoints; ping POST getHealth
- BlockRazor: Send Transaction v2 (plain Base64 body, Content-Type text/plain, auth in URI only); ping POST /v2/health; use default_http_client_builder
- SWQOS: all clients use default_http_client_builder (nextblock, temporal, zeroslot, astralane, lightspeed, jito, flashblock); remove unused Duration imports
Made-with: Cursor
These examples depend on a local path to sol-parser-sdk which is not
available in the public repo, causing build failures for consumers.
