- 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

- remove RELEASE_NOTES_v3.6.2.md; minor example/types/lib/params updates
Made-with: Cursor

- 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
- 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

Pass through the new field from TradeBuyParams to SwapParams so users
can opt-in to using buy_exact_sol_in and buy_exact_quote_in instructions.

Introduce TradingInfrastructure to allow multiple wallets to share the same
RPC client and SWQOS clients, reducing initialization overhead and memory usage.
Changes:
- Add InfrastructureConfig struct for wallet-independent configuration
- Add TradingInfrastructure struct to hold shared RPC/SWQOS clients
- Refactor TradingClient to use Arc<TradingInfrastructure>
- Add from_infrastructure() for fast client creation from shared infrastructure
- Add from_infrastructure_with_wsol_setup() for async WSOL ATA setup
- Maintain backwards compatibility with existing TradingClient::new() API
Benefits:
- First wallet: Full initialization (~200-500ms)
- Subsequent wallets (same config): Fast creation (~1-2ms)
- Memory: Single set of RPC/SWQOS clients shared across wallets
- 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
- Introduce DexParamEnum to replace Dex enum for protocol parameters
- Simplify TradeConfig::new() to accept only 3 essential parameters
- Update all examples to use new DexParamEnum API
- Optimize executor and params modules
- Remove deprecated wsol_use_seed and mint_use_seed parameters
- Fix fast_fn module exports
- Add TradeError struct with code, message, and instruction fields
- Enhance poll_transaction_confirmation to extract detailed error info from logs
- Change buy/sell return type from Option<anyhow::Error> to Option<TradeError>
- Add solana-transaction-status-client-types dependency
- Remove unused parallel.rs module
- Split use_seed_optimize parameter into two independent configs:
* wsol_use_seed: controls seed optimization for WSOL ATA operations (default: false)
* mint_use_seed: controls seed optimization for other mint ATA operations (default: true)
- Refactor TradeConfig to accept all parameters in new() constructor
- Remove deprecated builder methods (with_seed_config, with_wsol_ata_config)
- Add wsol_use_seed and mint_use_seed fields to SwapParams
- Remove open_seed_optimize field from SwapParams
- Update all instruction builders to use correct seed parameter:
* Use params.wsol_use_seed for WSOL token operations
* Use params.mint_use_seed for other token operations
* Fix token type detection in bonk.rs, raydium_cpmm.rs, and raydium_amm_v4.rs
to properly select wsol_use_seed when dealing with WSOL tokens
- Update wsol_manager functions to accept is_use_seed parameter:
* handle_wsol()
* close_wsol()
* create_wsol_ata()
* wrap_sol_only()
* wrap_wsol_to_sol()
- Add wrap_wsol_to_sol() function with smart temporary account selection:
* If source is seed-created, use normal ATA for temp account
* If source is normal ATA, use seed ATA for temp account
* Prevents address conflicts while optimizing performance
This provides fine-grained control over seed optimization strategies,
allowing different configurations for WSOL and other tokens.
