Key Components

Pool Discovery

rust
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

- 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
