```bash
npm set up web3
```
two. **Connect to the Ethereum Community**:
```javascript
const Web3 = need('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
three. **Keep track of Pending Transactions**:
```javascript
async operate monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Employ logic to detect big trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.error(error);
);
