front run bot bsc const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```

3. **Watch Pending Transactions**:
```javascript
async functionality monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Carry out logic to recognize substantial trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);

);
else
console.mistake(mistake);
