Rust SDK to interact with the dex trade Solana program.
Documentation

Sol Trade SDK

中文 | English | Telegram

A comprehensive Rust SDK for seamless interaction with Solana DEX trading programs. This SDK provides a robust set of tools and interfaces to integrate PumpFun, PumpSwap, Bonk, and Raydium CPMM functionality into your applications.

Project Features

  1. PumpFun Trading: Support for buy and sell operations
  2. PumpSwap Trading: Support for PumpSwap pool trading operations
  3. Bonk Trading: Support for Bonk trading operations
  4. Raydium CPMM Trading: Support for Raydium CPMM (Concentrated Pool Market Maker) trading operations
  5. Event Subscription: Subscribe to PumpFun, PumpSwap, Bonk, and Raydium CPMM program trading events
  6. Yellowstone gRPC: Subscribe to program events using Yellowstone gRPC
  7. ShredStream Support: Subscribe to program events using ShredStream
  8. Multiple MEV Protection: Support for Jito, Nextblock, ZeroSlot, Temporal, Bloxroute, and other services
  9. Concurrent Trading: Send transactions using multiple MEV services simultaneously; the fastest succeeds while others fail
  10. Unified Trading Interface: Use unified trading protocol enums for trading operations

Installation

Direct Clone

Usage Examples

Important Parameter Description

auto_handle_wsol Parameter

In PumpSwap, Bonk, and Raydium CPMM trading, the auto_handle_wsol parameter is used to automatically handle wSOL (Wrapped SOL):

  • Mechanism:
    • When auto_handle_wsol: true, the SDK automatically handles the conversion between SOL and wSOL
    • When buying: automatically wraps SOL to wSOL for trading
    • When selling: automatically unwraps the received wSOL to SOL
    • Default value is true

lookup_table_key Parameter

The lookup_table_key parameter is an optional Pubkey that specifies an address lookup table for transaction optimization:

  • Purpose: Address lookup tables can reduce transaction size and improve execution speed by storing frequently used addresses
  • Usage:
    • Can be set globally in TradeConfig for all transactions
    • Can be overridden per transaction in buy() and sell() methods
    • If not provided, defaults to None
  • Benefits:
    • Reduces transaction size by referencing addresses from lookup tables
    • Improves transaction success rate and speed
    • Particularly useful for complex transactions with many account references

7. Custom Priority Fee Configuration

use sol_trade_sdk::common::PriorityFee;

// Custom priority fee configuration
let priority_fee = PriorityFee {
    unit_limit: 190000,
    unit_price: 1000000,
    rpc_unit_limit: 500000,
    rpc_unit_price: 500000,
    buy_tip_fee: 0.001,
    buy_tip_fees: vec![0.001, 0.002],
    sell_tip_fee: 0.0001,
};

// Use custom priority fee in TradeConfig
let trade_config = TradeConfig {
    rpc_url: rpc_url.clone(),
    commitment: CommitmentConfig::confirmed(),
    priority_fee, // Use custom priority fee
    swqos_configs,
    lookup_table_key: None,
};

Supported Trading Platforms

  • 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

MEV Protection Services

  • Jito: High-performance block space
  • NextBlock: Fast transaction execution
  • ZeroSlot: Zero-latency transactions
  • Temporal: Time-sensitive transactions
  • Bloxroute: Blockchain network acceleration

New Architecture Features

Unified Trading Interface

  • TradingProtocol Enum: Use unified protocol enums (PumpFun, PumpSwap, Bonk, RaydiumCpmm)
  • Unified buy/sell Methods: All protocols use the same trading method signatures
  • Protocol-specific Parameters: Each protocol has its own parameter structure (PumpFunParams, RaydiumCpmmParams, etc.)

Event Parsing System

  • Unified Event Interface: All protocol events implement the UnifiedEvent trait
  • Protocol-specific Events: Each protocol has its own event types
  • Event Factory: Automatically identifies and parses events from different protocols

Trading Engine

  • Unified Trading Interface: All trading operations use the same methods
  • Protocol Abstraction: Supports trading operations across multiple protocols
  • Concurrent Execution: Supports sending transactions to multiple MEV services simultaneously

Price Calculation Utilities

The SDK includes price calculation utilities for all supported protocols in src/utils/price/.

Important Notes

  1. Test thoroughly before using on mainnet
  2. Properly configure private keys and API tokens
  3. Pay attention to slippage settings to avoid transaction failures
  4. Monitor balances and transaction fees
  5. Comply with relevant laws and regulations
