An educational reference implementation showing how to perform sandwich attacks on UniswapV2 pairs on Ethereum. It combines Yul+/Solidity contracts with a JavaScript bot that reads the mempool, decodes transactions, calculates profit and gas bribes, and fires bundles.
Use cases
- learn how MEV sandwich attacks work on Ethereum
- understand how to read and decode mempool transactions
- study a minimal sandwich bot implementation in Solidity and JavaScript
- learn how to calculate gas bribes and fire Flashbots bundles
- get a starting point for building MEV searcher bots
- see how UniswapV2 pair swaps can be exploited for profit
When to choose
- you want to learn MEV and sandwich attack mechanics from working source code
- you need a simple, low-barrier reference for building an Ethereum searcher bot
- you want to see how mempool monitoring and bundle submission fit together
When to avoid
- you need a production-ready bot with circuit breakers, poison token checks, and robust logging
- you want protection against uncle bandit attacks
- you need optimized gas usage or advanced searcher features
