one. **Setup Your Growth Ecosystem**:
- Install Node.js and npm.
- Set up Web3.js:
```bash
npm put in web3
```
two. **Connect to the Ethereum Network**:
```javascript
const Web3 = have to have('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
three. **Monitor Pending Transactions**:
```javascript
async function monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Implement logic to recognize big trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(mistake);
);
```
4. **Apply the Sandwich Method**:
```javascript
async purpose executeSandwichStrategy(tx)
// Determine preemptive and adhere to-up trade logic
