```javascript
const Web3 = involve('web3');
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 (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
