npm set up 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. **Keep an eye on Pending Transactions**:
```javascript
async perform monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Employ logic to recognize huge trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(mistake);
);
