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
    • Raydium AMM V4: Raydium's Automated Market Maker V4 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. Account State Monitoring: Real-time monitoring of protocol account states and configuration changes
  8. Transaction & Account Event Filtering: Separate filtering for transaction events and account state changes
  9. High Performance: Optimized for low-latency event processing
  10. Batch Processing Optimization: Batch processing events to reduce callback overhead
  11. Performance Monitoring: Built-in performance metrics monitoring, including event processing speed, etc.
  12. Memory Optimization: Object pooling and caching mechanisms to reduce memory allocations
  13. Flexible Configuration System: Support for custom batch sizes, backpressure strategies, channel sizes, and other parameters
  14. Preset Configurations: Provides high-performance, low-latency, ordered processing, and other preset configurations
  15. Backpressure Handling: Supports blocking, dropping, retrying, ordered, and other backpressure strategies
  16. Runtime Configuration Updates: Supports dynamic configuration parameter updates at runtime
  17. Full Function Performance Monitoring: All subscribe_events functions support performance monitoring, automatically collecting and reporting performance metrics

Installation

Direct Clone

Clone this project to your project directory:

cd your_project_root_directory
git clone https://github.com/0xfnzero/solana-streamer

Add the dependency to your Cargo.toml:

# Add to your Cargo.toml

solana-streamer-sdk = "0.3.2"

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/AMM V4)
  • 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.

Event Filtering

The library supports flexible event filtering to reduce processing overhead:

use solana_streamer_sdk::streaming::event_parser::common::{filter::EventTypeFilter, EventType};

// No filtering - receive all events
let event_type_filter = None;

// Filter specific event types - only receive PumpSwap buy/sell events
let event_type_filter = Some(EventTypeFilter { 
    include: vec![EventType::PumpSwapBuy, EventType::PumpSwapSell] 
});

Supported Protocols

  • PumpFun: Primary meme coin trading platform
  • PumpSwap: PumpFun's swap protocol
  • Bonk: Token launch platform (letsbonk.fun)
  • Raydium CPMM: Raydium's Concentrated Pool Market Maker protocol
  • Raydium CLMM: Raydium's Concentrated Liquidity Market Maker protocol
  • Raydium AMM V4: Raydium's Automated Market Maker V4 protocol

Event Streaming Services

  • Yellowstone gRPC: High-performance Solana event streaming
  • ShredStream: Alternative event streaming protocol

Architecture Features

Unified Event Interface

  • UnifiedEvent Trait: All protocol events implement a common interface
  • Protocol Enum: Easy identification of event sources
  • Event Factory: Automatic event parsing and categorization

Event Parsing System

  • Protocol-specific Parsers: Dedicated parsers for each supported protocol
  • Event Factory: Centralized event creation and parsing
  • Extensible Design: Easy to add new protocols and event types

Streaming Infrastructure

  • Yellowstone gRPC Client: Optimized for Solana event streaming
  • ShredStream Client: Alternative streaming implementation
  • Async Processing: Non-blocking event handling

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
