Solana Arbitrage Bot

An automated arbitrage bot that monitors and executes profitable trading opportunities between Jupiter and Raydium on Solana.

Key Features

• Real-time price monitoring
• Flash loan integration with Mango Markets
• Atomic execution via smart contract
• Slippage protection
• Gas cost optimization
• Rate limiting
• Health monitoring endpoint
