one. **Arrange Your Enhancement Environment**:
- Set up Node.js and npm.
- Install Web3.js:
```bash
npm set up web3
```
2. **Hook up with the Ethereum Community**:
```javascript
const Web3 = demand('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Watch Pending Transactions**:
```javascript
async perform monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Put into action logic to establish significant trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(error);
);
```

```javascript
async functionality executeSandwichStrategy(tx)
// Outline preemptive and follow-up trade logic
