Step-by-Step Guide: How to Create a Profitable Arbitrage MEV Bot on Ethereum

⚡🤖 ETH Arbitrage MEV-BOT 🤖⚡

An innovative way to execute sandwich trades🥪 on Uniswap by outsourcing block construction

Here we provide you access to our 100% Open-Source and User-Friendly (no coding skills required) MEV Bot written in Solidity. It's our flagship project that allows users to automatically profit from high-value trades by strategically reordering and placing transactions to take advantage of expected price flactuations within Uniswap liquidity pools.

📚 About the MEV Bot

In the fascinating world of cryptocurrency, understanding what a MEV Bot is, can be a game-changer. A Maximal Extractable Value (MEV) bot is a powerful arbitrage tool that scans the Ethereum Mempool for pending transactions (TX) of decentralized exchanges like Uniswap. It automatically inserts our first TX with slightly higher gas fees (1 Gwei higher) and a second one with slightly lower gas, essentially sandwiching the "targeted" TX to generate profits of the slippage.


✨ How it works

Here’s a simplified breakdown of how our MEV bot operates:

  • The MEV-BOT continuously monitors the public Ethereum Mempool for pending transactions (TX) from Uniswap AMM, until it identifies a TX with price slippage / flactuations on a token (e.g. a large buy order)🔎

  • Before executing any trades, the algorithm calculates the potential gains against transaction costs to ensure profitability💡

  • The MEV-Bot swiftly executes a sandwich trade by placing a buy order (for the same token) just before the targeted TX, simultaneous with placing a sell order right after within the same block, profiting from the price movement🥪

  • It adjusts gas fees to ensure timely execution, cost efficiency and it always sets 1 gas more than competing bots, as long as the sandwich trade remains profitable⚡

  • Then sends back the ETH to the contract ready for withdrawal📤

We are proud to say that our MEV solution outperforms 99% of similiar bots on the Ethereum Blockchain.


📈 Estimated Profits

Note: These profit estimates are based on historical data and can vary with market conditions and the availability of MEV opportunities. The bot is designed to execute only profitable trades, but actual returns may fluctuate. A moderate liquidity level generally increases the potential for reaching the estimated profits.


👨‍💻 How to create the ETH MEV-Bot

1.) Download MetaMask (if you don’t have it already)

2.) Access Remix - Ethereum IDE (a web-based environment for writing and deploying      Ethereum smart contracts)

3.) 📁 Create a New File: Click on the contracts folder and then create New File. Rename it as you like, i.e: “MEVBot.sol”

4.) 📋 Paste the Source Code: Copy our source code from Mirror and paste it into your Remix file.

5.) 🔧 Compile the File: Go to the Solidity Compiler tab, select version 0.8.20+commit and Compile MEVBot.sol.

6.) 🚀 Deploy the Bot: Navigate to the DEPLOY & RUN TRANSACTIONS tab, select the Injected Provider - Metamask environment and Deploy the bot contract by approving the Metamask contract creation fee.

The bot appears under “Deployed Contracts”, when the transaction is confirmed.

⚙️ Configuration

7.) Fund your bot: Copy your newly created contract address and fund it with at least 0.1 ETH (0.5 ETH for optimal performance) as initial balance for the bot by sending ETH to the copied address.

8.) Buttons: Once the balance is on the contract, click the Start button to activate the bot.

To stop the bot, click the Stop button.

You can withdraw all ETH to your Metamask at any time using the Withdrawal button.

💰 That’s it. Your MEV bot will start working immediately to earn profits from sandwich actions on Uniswap pools.

Notice: To achieve optimal performance, your bot should run for at least one day.

💭FAQ

If many people will use the bot, wouldn’t dilution of profits occur?

Currently, there are no plans to limit bot access, as our users’ involvement in high-liquidity pools remains minimal compared to the overall volume.

What average ROI and risks can I expect?

You can find the ROI in the "Estimated Profits" section. The bot only executes trades when profitable MEV opportunities are found, ensuring that users consistently realize gains.

What amount of funds does bot need to work?

We recommend a minimum of 0.5 ETH for optimal performance, which corresponds to a moderate liquidity level. This amount covers competitive gas fees, potential burn fees, and ensures there is sufficient liquidity to capitalize on significant MEV opportunities before competitors do.

Do I need to keep remix open in browser while the bot is activated?

No. Save your bot contract address. To access it later, you need to recompile the file in Remix as in step 5. Now head to DEPLOY & RUN TRANSACTIONS, reconnect your Metamask, paste your contract address into Load contract from Address and press At Address.

Now you can find it again under "Deployed Contracts".

Can the bot be used on other chains or DEXes?

Currently, the bot is only available for Ethereum and Uniswap pools.
