Solana MEV Arbitrage Bot

Overview

A high-frequency trading bot designed to identify and exploit arbitrage opportunities across various decentralized exchanges (DEXs) on the Solana blockchain.

Features

• Multi-DEX Support: Works with Raydium, Orca Whirlpools, and Meteora DEXs
• Real-time Pool Monitoring: Continuously scans for new liquidity pools
• Advanced Arbitrage Detection: Identifies profitable 1-hop and 2-hop arbitrage paths
• Simulation Engine: Tests potential trades before execution
• Optimized Execution: Prioritizes the most profitable opportunities
• Performance Tracking: Records all arbitrage attempts and results

Supported DEXs

• Raydium (CLMM and standard pools)
• Orca Whirlpools
• Meteora

Key Components

Pool Discovery

pub async fn get_fresh_pools(tokens: Vec<TokenInArb>) -> HashMap<String, Market> {
    // Scans supported DEXs for new pools containing specified tokens
    // Implements rate limiting between requests
}

## Configuration

Edit `src/common/constants.rs` to configure:

- RPC endpoints
- DEX program IDs
- Rate limits
- Profit thresholds
- MongoDB connection settings


## Performance Optimization

The bot includes several optimization features:

- Batch processing with `get_multiple_accounts` for efficient RPC usage
- Market filtering based on liquidity thresholds
- Real-time WebSocket subscriptions for immediate market updates
- MongoDB for persistent storage and performance analysis
- Error rate limiting for problematic paths


## Monitoring

The bot outputs:

- Real-time progress bars
- Detailed logs of arbitrage opportunities with emoji indicators (💦, 👀, 📊)
- JSON files with trade results
- MongoDB integration for persistent storage and analysis
