npm set up web3
```
2. **Connect with the Ethereum Community**:
```javascript
const Web3 = need('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 =>
// Apply logic to discover substantial trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.error(error);
);
