- 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 Meteora DAMM V2 trading protocol with instruction builder, type definitions, and fixed_output_token_amount parameter for precise output control. Update all examples and documentation.
- Add Raydium CPMM constants, instruction builder and pool implementation
- Implement unified buy/sell trading interface and event parsing system
- Update documentation and examples to support new protocol
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
- Add unified TradeExecutor interface and protocol abstraction
- Refactor PumpFun/PumpSwap into adapter pattern
- Introduce TradeFactory for multi-protocol support
- Add parallel execution and unified parameter system
- Include Raydium protocol support and log parsing
- Simplify codebase structure and improve maintainability
