Built for DeFi enthusiasts who want to explore Ethereum MEV (Maximal Extractable Value) trading strategies.
- Avg. Daily Return: 7–9% on deployed capital (varies with market volatility).
- Minimum Capital Requirement: 0.5 ETH (under current gas and liquidity conditions).
- Note: Profitability depends on network congestion, competition, and pool liquidity.
- Disclaimer: No guarantees. Past performance does not predict future results.

This bot monitors pending transactions in the Ethereum mempool for large swaps on Uniswap. When it detects a high-slippage transaction, it executes a three-step strategy:
- Buys the target asset before the large swap.
- Waits for the target swap to shift the asset’s price.
- Sells the asset at the optimized price.
The bot can perform multiple transactions if necessary to capture an opportunity.
- Automatically monitors the Ethereum mempool and executes MEV strategies.
- Dynamic gas pricing to remain competitive.
- Built-in reverts for failed transactions and profit thresholds to filter unprofitable trades.
- Open-source and modular codebase for tweaking strategies (e.g., profit thresholds, gas multipliers, etc.).
Download and set up MetaMask or any other EVM-compatible wallet.
Access Remix - Ethereum IDE, a web-based environment for writing, compiling, and deploying Ethereum smart contracts.
📁 Create a new file in Remix and name it, e.g., bot.sol.
📋 Copy the bot code from GitHub and paste it into your newly created Remix file.
🔧 Go to the Solidity Compiler tab, select version 0.6.6+commit, and click Compile bot.sol.
🚀 Navigate to the Deploy & Run Transactions tab, select the Injected Provider - MetaMask environment, and click Deploy. Approve the MetaMask contract creation fee to deploy your MEV bot.
Copy your newly deployed contract address and fund it with at least 0.2 ETH as the initial balance by sending ETH to the contract address.
Use the following buttons to manage your bot:
- Start: Click the
Startbutton to activate the bot after funding. - Stop: Click the
Stopbutton to halt bot operations. - Withdrawal: Click the
Withdrawalbutton to withdraw all ETH to the owner (the wallet address that deployed the bot).

Reminder: Open-source does not equal endorsement. Use responsibly.
If you find this project helpful, please consider giving it a star on GitHub. Your support motivates further development and improvements.
No, you can close Remix after deploying the bot. Save the bot's contract address. To access it later, recompile the code in Remix as in step 5, go to Deploy & Run Transactions, reconnect MetaMask, paste your contract address into Load contract from Address, and click At Address. The bot will appear under "Deployed Contracts".
Currently, the bot is designed exclusively for Ethereum and Uniswap pools.
