## 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>
- Add SWQOS_ENDPOINTS_BLOCKRAZOR_GRPC with correct gRPC endpoints
- Add Grpc variant to SwqosTransport enum
- Add get_endpoint_with_transport() method for transport-aware endpoint selection
- Change BlockRazor default: transport=None now uses gRPC (was HTTP)
- Require explicit Some(SwqosTransport::Http) for HTTP fallback
This fixes the issue where BlockRazor was incorrectly using HTTP endpoints
when gRPC was intended. Users can now use gRPC by default or explicitly
specify HTTP transport when needed.

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 BlockRazorBackend enum to support both gRPC and HTTP transport
- Default to gRPC for better performance, HTTP available via explicit selection
- Update SwqosConfig::BlockRazor to accept optional SwqosTransport parameter
- Implement keep-alive ping task for both gRPC and HTTP backends
- Follow same backend pattern as Astralane (Quic/Http) and Node1 (Quic/Http)
- Manual gRPC client implementation to avoid proto compilation issues
Usage:
- Default: BlockRazorClient::new() uses gRPC
- HTTP: BlockRazorClient::new_http() for HTTP transport
- Config: SwqosConfig::BlockRazor(token, region, url, None) for gRPC
- Config: SwqosConfig::BlockRazor(token, region, url, Some(Http)) for HTTP

- Add HTTP keep-alive ping task (30s interval) using free getHealth method
- Switch from JSON-RPC to faster Binary-Tx endpoint (/txb) for transaction submission
- Send raw binary transaction bytes directly to avoid encoding/decoding overhead
- Update response handling for Binary-Tx plain text status codes (200/403/419/500)
- Follow same keep-alive pattern as BlockRazor, Stellium, and Astralane clients
These changes reduce first-submit cold start latency and overall transaction submission time.

- 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.
Made-with: Cursor
- Rename wait_transaction_confirmed to wait_tx_confirmed (params, lib, docs, examples)
- SDK timing: use [SDK][provider] style with fixed-width labels; add newline before block
- Move print_sdk_timing_block to common::sdk_log; unify SWQOS_LABEL_WIDTH
- SWQOS submitted/failed: aligned [Provider] labels via log_swqos_submitted/submission_failed
- Extract short error message from JSON (message/data) or quoted string; prefix with 'error: '
- Format elapsed as 'X.XXXX ms' or 'X.XXXX µs' (4 decimals, space before unit); use comma before error
- Add SwqosType::as_str() for zero-allocation log labels; only parse JSON when input starts with '{'
Made-with: Cursor
- 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
- transaction_pool: add PARALLEL_SENDER_COUNT (18), ensure prefill >= 18 so
multi-channel build never serializes; prefill 64 with max(PREFILL, 18)
- async_executor: document that pool prefill must match sender thread count
- executor: do not sort submit_timings (avoids any extra work); comment that
log order is completion order
- docs: add ASYNC_EXECUTOR_REVIEW.md
- remove RELEASE_NOTES_v3.6.2.md; minor example/types/lib/params updates
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
- Log build_instructions / before_submit once; per-channel submit, confirmed, total (all from grpc_recv_us)
- confirmed = per-channel submit-to-confirm duration; total = batch start-to-confirm when need_confirm
- No logging between execute_parallel and poll_any_transaction_confirmation to reduce latency
- Clone submit_timings only when log_enabled; all logging after result is ready
- Use provider name (Jito, Helius, etc.) in log lines instead of generic SWQOS
- Timing format: .4 ms; simulate (dry-run) label for simulate mode
- execute_parallel returns 4-tuple with submit_timings for per-channel timing
Made-with: Cursor
- Add Helius Sender client (helius.rs) with dual routing and swqos_only mode
- Helius min tip: 0.0002 SOL default, 0.000005 SOL when swqos_only=true
- Add TradeConfig.check_min_tip (default false) to skip min-tip validation for lower latency
- Thread check_min_tip through SwapParams and execute_parallel; only call min_tip_sol when enabled
- Add SWQOS_ENDPOINTS_HELIUS and HELIUS_TIP_ACCOUNTS in constants
- Extend SwqosConfig/SwqosType for Helius; add Helius to get_endpoint and get_swqos_client
- Update trading_client, shared_infrastructure and middleware_system examples
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
- Make serialize_transaction_and_encode sync and route through buffer pool
(serialization::serialize_transaction_sync) to cut allocs on hot path
- Build single-submit body with format! instead of json!+to_string() in bloxroute
- Add serialize_transactions_batch_sync; bloxroute batch uses it and format! for entries
- Fix first-submit cold start: immediate first ping, then 30s keepalive interval
- Fix high latency after ~5 min: pool_max_idle_per_host=4, pool_idle_timeout=300s
(BlockRazor, Temporal, Node1, Astralane, Stellium) so submit reuses ping connection
- Ping: 1.5s timeout, consume response body so connection returns to pool
- poll_transaction_confirmation: avoid cloning status.value[0], use ref
- Translate all swqos comments to English

- Add SWQOS_BLACKLIST constant for disabling specific providers
- Add SwqosConfig::is_blacklisted() method to check blacklist status
- Skip blacklisted providers during client initialization with warning
- Remove NextBlock references from README, README_CN and examples
- NextBlock is blacklisted by default, can be enabled by removing from SWQOS_BLACKLIST
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..]

* handle_wsol()
* close_wsol()
* create_wsol_ata()

* Prevents address conflicts while optimizing performance
This provides fine-grained control over seed optimization strategies,
allowing different configurations for WSOL and other tokens.
