1. **Setup Your Progress Environment**:
- Install Node.js and npm.
- Set up Web3.js:
```bash
npm put in web3
```
two. **Connect to the Ethereum Network**:
```javascript
const Web3 = call for('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Observe Pending Transactions**:
```javascript
async perform monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Employ logic to detect big trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(mistake);
);

async functionality executeSandwichStrategy(tx)
// Define preemptive and comply with-up trade logic
