Solana Streamer

中文 | English | Telegram

A lightweight Rust library for real-time event streaming from Solana DEX trading programs. This library provides efficient event parsing and subscription capabilities for PumpFun, PumpSwap, Bonk, and Raydium CPMM protocols.

Project Features

1. Real-time Event Streaming: Subscribe to live trading events from multiple Solana DEX protocols
2. Yellowstone gRPC Support: High-performance event subscription using Yellowstone gRPC
3. ShredStream Support: Alternative event streaming using ShredStream protocol
4. Multi-Protocol Support:
   • PumpFun: Meme coin trading platform events
   • PumpSwap: PumpFun's swap protocol events
   • Bonk: Token launch platform events (letsbonk.fun)
   • Raydium CPMM: Raydium's Concentrated Pool Market Maker events
   • Raydium CLMM: Raydium's Concentrated Liquidity Market Maker events
5. Unified Event Interface: Consistent event handling across all supported protocols
6. Event Parsing System: Automatic parsing and categorization of protocol-specific events
7. High Performance: Optimized for low-latency event processing
8. Batch Processing Optimization: Batch processing events to reduce callback overhead
9. Performance Monitoring: Built-in performance metrics monitoring, including event processing speed, etc.
10. Memory Optimization: Object pooling and caching mechanisms to reduce memory allocations
11. Flexible Configuration System: Support for custom batch sizes, backpressure strategies, channel sizes, and other parameters
12. Preset Configurations: Provides high-performance, low-latency, ordered processing, and other preset configurations
13. Backpressure Handling: Supports blocking, dropping, retrying, ordered, and other backpressure strategies
14. Runtime Configuration Updates: Supports dynamic configuration parameter updates at runtime
15. Full Function Performance Monitoring: All subscribe_events functions support performance monitoring, automatically collecting and reporting performance metrics

Usage Examples

Quick Start - Parse Transaction Events

You can quickly test the library by running the built-in example that parses transaction events:

cargo run --example parse_tx_events

This example demonstrates:

• How to parse transaction data from Solana mainnet using RPC
• Event parsing for multiple protocols (PumpFun, PumpSwap, Bonk, Raydium CPMM/CLMM)
• Transaction details extraction including fees, logs, and compute units

The example uses a predefined transaction signature and shows how to extract protocol-specific events from the transaction data.

Performance Considerations

1. Connection Management: Properly handle connection lifecycle and reconnection
2. Event Filtering: Use protocol filtering to reduce unnecessary event processing
3. Memory Management: Implement appropriate cleanup for long-running streams
4. Error Handling: Robust error handling for network issues and service interruptions
5. Batch Processing Optimization: Use batch processing to reduce callback overhead and improve throughput
6. Performance Monitoring: Enable performance monitoring to identify bottlenecks and optimization opportunities

Important Notes

1. Network Stability: Ensure stable network connection for continuous event streaming
2. Rate Limiting: Be aware of rate limits on public gRPC endpoints
3. Error Recovery: Implement proper error handling and reconnection logic
4. Compliance: Ensure compliance with relevant laws and regulations
