Whenever you use a decentralized exchange to swap tokens, the price of the token you buy increases slightly. This is called slippage and for most retail traders, slippage is barely even noticeable. Whale traders however, especially when they purchase highly illiquid tokens, can significantly change a token’s price.Frontrunning bots take advantage of this mechanic by beating out the trader on the gas fees, purchasing into a token at the lower price and then instantly selling them off at the higher price. In a block explorer, frontruns leave a clear trace with the trader’s transaction being sandwiched between the two frontrun transactions. #coding #frontrunningbot #javascript #tutorial #botv4 #dex #programming #configuration #learntocode #stepbystep #beginner 40 | -------------------------------------------------------------------------------- /Web3.js: -------------------------------------------------------------------------------- 1 | require('dotenv').config() 2 | const Web3 = require('web3') 3 | const { ChainId, Fetcher, WETH, Route, Trade, TokenAmount, TradeType, Percent } = require('@uniswap/sdk') 4 | const ethers = require('ethers') 5 | const fs = require('fs') 6 | //const assert = require('assert'); 7 | 8 | let divider = "\n------------------------------------------------------\n" 9 | 10 | const chainId = ChainId.MAINNET 11 | 12 | let web3HD 13 | let token 14 | let route 15 | let weth 16 | let provider 17 | let signer 18 | let uniswap 19 | 20 | const ACCOUNT = process.env.REACT_APP_ACCOUNT 21 | const TOKEN_ADDRESS = process.env.REACT_APP_TOKEN_ADDRESS 22 | const EXCHANGE_ADDRESS = process.env.REACT_APP_EXCHANGE_ADDRESS 23 | const ETH_AMOUNT = process.env.REACT_APP_ETH_AMOUNT 24 | 25 | const web3 = new Web3(process.env.REACT_APP_RPC_URL_WSS) 26 | web3HD = new Web3(new Web3.providers.HttpProvider(process.env.REACT_APP_RPC_URL)) 27 | provider = new ethers.getDefaultProvider(process.env.REACT_APP_RPC_URL) 28 | const privateKey = new Buffer.from(process.env.REACT_APP_PRIVATE_KEY, "hex"); 29 | signer = new ethers.Wallet(privateKey, provider) 30 | 31 | // declare the token contract interfaces 32 | tokenContract = new ethers.Contract( 33 | TOKEN_ADDRESS, 34 | ['function balanceOf(address owner) external view returns (uint)', 35 | 'function decimals() external view returns (uint8)', 36 | 'function approve(address spender, uint value) external returns (bool)'], 37 | signer 38 | ); 39 | 40 | // declare the Uniswap contract interface 41 | uniswap = new ethers.Contract( 42 | EXCHANGE_ADDRESS, 43 | ['function swapExactETHForTokens(uint amountOutMin, address[] calldata path, address to, uint deadline) external payable returns (uint[] memory amounts)', 44 | 'function swapExactTokensForETH(uint amountIn, uint amountOutMin, address[] calldata path, address to, uint deadline) external returns (uint[] memory amounts)', 45 | 'function swapETHForExactTokens(uint amountOut, address[] calldata path, address to, uint deadline) external payable returns (uint[] memory amounts)'], 46 | signer 47 | ); 48 | 49 | let addtrxflag = false 50 | let trxflag = false 51 | let initialTokenBalance 52 | let tokenBalanceAfterBuy 53 | let tokensToSell 54 | 55 | async function run(){ 56 | 57 | console.log('\x1b[1m\x1b[37m[Bot]: Process has been started! \x1b[1m\x1b[31m(to stop press CTRL+C anytime)\x1b[0m\n') 58 | console.log('\x1b[1m\x1b[37m[Bot]: Looking for targets at DEX...\x1b[0m\n') 59 | 60 | fs.writeFile('./transactions_hashes.txt', '', function(){console.log('\x1b[1m\x1b[37m[Bot]: transactions_hashes.txt \x1b[1m\x1b[32mwiped!\n\x1b[0m\n\n')}) 61 | 62 | token = await Fetcher.fetchTokenData(chainId, TOKEN_ADDRESS) 63 | weth = WETH[chainId] 64 | const pair = await Fetcher.fetchPairData(token, weth, provider) 65 | route = new Route([pair], weth) 66 | 67 | initialTokenBalance = await tokenContract.balanceOf(ACCOUNT); 68 | 69 | if(true){ 70 | subscription = web3.eth.subscribe('pendingTransactions', function (error, result) {}) 71 | .on("data", function (transactionHash) { 72 | web3.eth.getTransaction(transactionHash) 73 | .then(function (transaction) { 74 | if(transaction && !trxflag){ 75 | parseTransactionData(transaction) 76 | } 77 | }) 78 | .catch(function () { 79 | console.log("\x1b[1m\x1b[Bot]: WARNING!
