- Add fast_fn module with global caches for PDA, ATA, and instruction operations
- Implement memory-efficient caches using CLRU and parking_lot for thread-safe access
- Optimize compute budget instruction generation with caching
- Replace std::sync::Mutex with parking_lot::Mutex for better performance
- Add dedicated caching for PumpFun PDAs and associated token addresses
- Improve transaction building with batch signature optimization
- Add new dependencies: clru, smallvec, parking_lot for cache infrastructure
- Remove unused utility functions in pumpfun module
- Enhance error messages for tip fee configuration validation
- Remove redundant transaction builder functions and merge into single build_transaction()
- Simplify compute budget manager with unified add_compute_budget_instructions()
- Consolidate trade executor interface by removing separate buy/sell methods
- Unify BuyParams/SellParams usage, remove *WithTipParams structs
- Streamline parallel execution logic and remove TradeType parameter
- Delete obsolete files: address_lookup.rs, tip_cache.rs
- Clean up nonce manager by removing unused is_using_nonce() function
This refactoring reduces code duplication and provides a cleaner, more maintainable API
for transaction building and execution across all trading protocols.
- Add SubscriptionHandle struct to manage async subscription tasks
- Implement graceful shutdown mechanism with unsub_fn callback
- Export new module in common/mod.rs
- Support for proper resource cleanup in subscription management
Major changes:
- Refactor event parsing system: migrate scattered logs_* modules to unified event_parser architecture
- Add unified UnifiedEvent trait and EventParser trait for standardized event parsing interface
- Introduce GenericEventParser and EventParserFactory for plugin-style protocol extension
- Add match_event! macro to simplify event type matching and handling
- Add Raydium Launchpad (Bonk.fun) protocol support:
- Complete buy/sell trading functionality
- Pool state management and querying
- Event parsing and subscription
- Update trading system to support new protocol architecture
- Refactor constants organization, rename raydium to raydium_launchpad
- Update documentation and example code
Technical improvements:
- Unified event interface design for better code maintainability
- Factory pattern implementation for dynamic protocol loading
- Generic event parser to reduce code duplication
- Improved error handling and type safety
Breaking Changes:
- Remove old logs_* modules, use new event_parser system
- Protocol constants path change: raydium -> raydium_launchpad
- Event subscription API updated to unified interface
