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

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 proper cleanup for long-running streams
  4. Error Handling: Robust error handling for network issues and service disruptions

Configuration Options

Yellowstone gRPC Configuration

let grpc = YellowstoneGrpc::new(
    "https://solana-yellowstone-grpc.publicnode.com:443".to_string(),
    None, // Custom configuration options
)?;

ShredStream Configuration

let shred_stream = ShredStreamGrpc::new("http://127.0.0.1:10800".to_string()).await?;

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. Resource Management: Monitor memory and CPU usage for long-running streams
  5. Compliance: Ensure compliance with relevant laws and regulations
