- Add Token2022 extended state parsing
- Add pumpswap pool monitoring example
- Enhance AccountFilter with memcmp filters
BREAKING CHANGE: API signature changes for subscription methods
- Rename CommonAccountEvent to TokenAccountEvent for better semantic clarity
- Rename AccountNonce to NonceAccount for consistent naming convention
- Add MintInfoEvent type to support SPL Token Mint account parsing
- Enhance parse_token_account_event to automatically detect and parse Mint accounts
- Update all example code to use new event types and structures
- Improve event type semantics for better developer experience
- feat(examples): add nonce_listen_example for nonce account tracking
- feat(examples): add token_balance_listen_example for balance monitoring
- feat(parser): implement NonceAccountEvent with nonce state parsing
- feat(types): add AccountNonce event type to filtering system
- docs: update README with new monitoring examples
- chore: bump version to 0.4.2
- Add requires_inner_instruction field to GenericEventParseConfig
- Skip events that require but lack inner instruction data during processing
- Set PumpFun migrate events to require inner instructions (prevents parsing failed migrations)
- Add EventTypeFilter for precise event type filtering
- Refactor metrics to track events by type (tx/account/block)
- Add parser caching for improved performance
- Enhance gRPC subscription management
- Update examples and type definitions
- Add account event parser (account_event_parser.rs) for account-level event handling
- Introduce type definitions for pumpfun, pumpswap, raydium_amm_v4, raydium_clmm, raydium_cpmm protocols
- Enhance event processor to support account event processing alongside transactions
- Improve subscription system with separate transaction and account filters
- Optimize parser configuration using Option types for cleaner code structure
- Update examples and documentation to reflect new capabilities
Changes include:
- 6 new types.rs files for protocol-specific data structures
- Updated event processor for account, transaction, and block meta events
- Refactored subscription manager with account filtering support
- Enhanced metrics and batch processing logic
- Refactor streaming architecture with modular grpc components
- Add batch processing system with backpressure strategies
- Implement performance monitoring and metrics collection
- Add multi-protocol parser with block metadata support
- Enhance configuration system with preset profiles
- Add parse_tx_events example and update documentation
- Optimize yellowstone_grpc client complexity
- Bump version to 0.1.11
- Upgrade Solana deps to 2.3.x, yellowstone-grpc to 8.0.0
- Fix inner instruction indexing and timestamp handling
- Improve PumpFun/PumpSwap parser program ID support
This update includes the following improvements:
- Version upgraded to 0.1.5
- Added subscribe_events_v2 API with more granular account filtering
- Marked original subscribe_events API as deprecated
- Fixed bug
1. Version upgrade: SDK version updated from 0.1.3 to 0.1.4
2. Remove BlockMetaEvent: Delete unnecessary block metadata event type and related code
3. Optimize event handling: Add block_time and block_time_ms fields to each event
4. Code optimization: Improve code formatting and structure
5. Example updates: Update example code and usage instructions in README
- Implement BlockMetaEvent and SDKSystemEventParser
- Support block metadata subscription and processing
- Optimize event handling with separate tokio tasks
- Add commitment parameter support
- Upgrade version to 0.1.3
- Bump version to 0.1.2
- Add TransferData struct for transaction data parsing
- Implement parse_transfer_datas_from_next_instructions function to extract transfer data from subsequent instructions
- Enhance UnifiedEvent trait with set_transfer_datas method
- Optimize transfer data extraction when parsing inner instructions
- Support transfer data parsing for multiple protocols (PumpFun, PumpSwap, Bonk, Raydium, etc.)
- Improve support for Token Program, Token 2022 Program, and System Program transfer instructions
