npm put in web3
```
two. **Connect to the Ethereum Community**:
```javascript
const Web3 = call for('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Watch Pending Transactions**:
```javascript
async function monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Apply logic to discover significant trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.error(mistake);
);

// Define standards for a considerable transaction
return tx.benefit && web3.utils.toBN(tx.value).gt(web3.utils.toBN(web3.utils.toWei('1', 'ether')));
