Rust MEV template

• Template for building Rust-based MEV / frontrunning / sandwich bots.
• Created to learn more about blockchain MEV and Rust.
• Use it as a starting point.

Dependencies

• Rust

Requirements

• WebSocket node (e.g. QuickNode, Alchemy, ...)
• Hosting near the node (for low latency) (optional)

Foreword

• Fork it, go crazy.
• Contributions, or error fixes, welcomed via PR.
• Far from complete; a starting point.
• Severe lack of MEV resources, I hope this helps getting started.
• Not all chains expose mempool data.

Why?

• Attaining a better understanding of MEV.
• Rust chosen for its performance and multi-threading.
• Websockets for fast transaction detection, mempool access.
• Uniswap V2 routers because they're easy to understand.

What it does

• Listens to mempool
• Uses websockets for fastest possible detection
• Asynchronously checks if transactions are made against a specific router

What it doesn't do

• Make money
• Handle errors

What you need to do

• Add your own logic
• Add your own error handling
• Add your own websocket node
• ... and more

Other notes

• main.rs is the entry point.
• /abi contains a few router ABIs I've used
  • they're uniswap v2 variants
  • mev1.json is a custom ABI for a custom MEV contract (will see if I can find the source for this at some point) (not required, but can save gas fees)
• Will release other experiments in the future, need to sanitize repos.
