Route gRPC, ShredStream, and account parsing through sol-parser-sdk.
Remove local protocol parsing implementations.
Depend on sol-parser-sdk v0.4.8 from crates.io.
- Extend on-chain Pool layout (is_cashback_coin, 7-byte reserved, 244 bytes)
with backward-compatible decode for 236-byte legacy accounts
- Decode Buy/Sell program logs manually: min_base_amount_out, ix_name,
cashback fields; optional sell cashback when payload >= 368 bytes
- Set ix_name on buy / buy_exact_quote_in instructions; merge new fields
in CPI log merger
- Add read_i64_le helper and pool layout unit test
Made-with: Cursor
- global_state: only decrement signature_count when remove() actually removed entry
- types: bounds-check program_id_index and account indices in swap extraction
- types: require data.len() >= 9/12 before slicing token instruction data
- types: use i32 for current_index and safe skip count to avoid i8 truncation/UB
- event_parser: encode recent_blockhash only when len() == 32; pass i32 to swap parsers
Made-with: Cursor
- Remove standalone bs58 dependency and rely on the solana_sdk re-export
- Switch system and token program IDs to the idiomatic spl_token / solana_sdk constants
- Use pubkey! and LazyLock for cleaner program ID initialization
- Alias solana_entry::Entry as SolanaEntry to avoid a naming conflict with gRPC types
- Remove unused FromStr imports and some redundant logic
- EventMetadata: add recent_blockhash (Option<Vec<u8>>)
- gRPC path: extract from message.recent_blockhash, thread through parse_instruction_events_from_grpc_transaction and parse_events_from_grpc_instruction
- VersionedTransaction path: get from message.recent_blockhash(), pass into parse_events_from_instruction
- BlockMeta event: pass None for recent_blockhash
Made-with: Cursor
- Remove 'wide' and 'simd_utils.rs', rely on compiler auto-vectorization.
- Deduplicate swap parsing in 'types.rs' and 'merger_event.rs' using generic traits and local macros.
- Improve signature cleanup in 'global_state.rs' to avoid large heap allocations.
- Replace manual metadata accessors in 'traits.rs' with a macro for all variants.
- Remove unused types (ParseResult, ProtocolInfo) and legacy commented code.
- Fix Clippy lints (is_empty, copied) and restore missing trait imports.
- Add tx_index to TransactionWithSlot (entry index), pass to parser
- Emit PumpFun Migrate even when no CPI (shred gets instruction-only)
- Merge: only overwrite Create/CreateV2 with CPI when value non-default
- Rename transaction_index -> tx_index across codebase
- Add docs/SHREDSTREAM_LIMITATIONS.md (ALT/CPI limits, field completeness)
- Comment shred path: static_account_keys only, no inner_instructions
Made-with: Cursor
Add support for parsing SetComputeUnitLimit and SetComputeUnitPrice instructions from Solana's Compute Budget Program. Update event parser to handle compute budget instructions and bump version to 1.1.3.
- Replace instance-based EventParser with static method design
- Introduce ParserCache module for protocol config caching
- Simplify EventProcessor to pure functional handlers
- Optimize metrics: remove min/max tracking, keep last + avg only
- Reduce atomic operations in hot path for better performance
- Convert UnifiedEvent from trait object (Box<dyn UnifiedEvent>) to concrete enum type
- Remove match_event! macro in favor of native match expressions
- Simplify event metadata access: event.event_type() -> event.metadata().event_type
- Unify event callback signatures: Fn(Box<dyn UnifiedEvent>) -> Fn(UnifiedEvent)
- Update all example code to use the new enum-based event system
- Optimize type system to reduce runtime overhead and improve type safety
Affected scope:
- Core event parser and processor
- All protocol event definitions (PumpFun, PumpSwap, Bonk, Raydium series, etc.)
- gRPC and Shred streaming modules
- All example code
- 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 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
