npm put in web3
```
2. **Connect with the Ethereum Community**:
```javascript
const Web3 = require('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Keep an eye on Pending Transactions**:
```javascript
async functionality monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Put into action logic to establish huge trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(mistake);
);
```
4. **Employ the Sandwich System**:
```javascript
async function executeSandwichStrategy(tx)
// Define preemptive and comply with-up trade logic
