npm install 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. **Keep track of Pending Transactions**:
```javascript
async perform monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Carry out logic to identify huge trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.error(error);
);
```
4. **Implement the Sandwich Strategy**:
```javascript
async operate executeSandwichStrategy(tx)
// Determine preemptive and abide by-up trade logic
