one. **Setup Your Growth Ecosystem**:
- Install Node.js and npm.
- Install Web3.js:
```bash
npm set up web3
```
two. **Hook up with the Ethereum Network**:
```javascript
const Web3 = call for('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Check Pending Transactions**:
```javascript
async operate monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Put into practice logic to detect big trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(mistake);
);
```
four. **Implement the Sandwich Method**:
```javascript
async purpose executeSandwichStrategy(tx)
// Determine preemptive and follow-up trade logic
