What it does

The MEV Arbitrage Bot is a smart contract designed to identify and execute arbitrage opportunities between Uniswap pools and routers on the Ethereum blockchain. It operates through an external Python automation script that manages its execution without manual intervention.

Why it's interesting

This bot combines a Solidity smart contract with a Python automation layer, allowing for a seamless deployment and operation process. Its focus on MEV (Miner Extractable Value) arbitrage sets it apart from simpler trading bots that may not leverage complex transaction strategies.

How it works

The bot's core functionality is encapsulated in the executeArbitrage() function, which searches for arbitrage opportunities and executes trades in a single transaction. It includes various configuration functions for managing allowed routers and tokens, as well as emergency controls like pausing operations. The bot checks for arbitrage opportunities at regular intervals using a dry-run method (eth_estimateGas) to determine if a transaction would succeed before sending it. The README does not specify how the Python automation script interacts with the smart contract beyond starting the bot and monitoring events.

Get started in 5 minutes

  1. Open the EtherLab website to create and deploy the bot.
  2. Create a new .sol file and paste the smart contract code.
  3. Compile the contract using version 0.8.20.
  4. Deploy the contract and fund it with 0.5 to 1 ETH.
  5. Start the bot via the Python Automation tab and confirm in your wallet.

Watch out for

The repository has a moderate star count (1327) but was created recently (July 2026), indicating it may still be in development or lack extensive community testing. The README mentions that returns are not guaranteed and depend on market conditions, which introduces risk. Additionally, there are no details on licensing or security audits, which are critical for smart contract deployments.
