- Put in Node.js and npm.
- Put in Web3.js:
```bash
npm put in web3
```

two. **Connect to the Ethereum Community**:
```javascript
const Web3 = have to have('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```

3. **Observe Pending Transactions**:
```javascript
async function monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Employ logic to detect large trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);

);
else
console.mistake(error);
