npm install web3
```
two. **Hook up with the Ethereum Network**:
```javascript
const Web3 = demand('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
three. **Observe Pending Transactions**:
```javascript
async perform monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Carry out logic to determine big trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(mistake);
);
