one. **Put in place Your Improvement Atmosphere**:
- Install Node.js and npm.
- Set up Web3.js:
```bash
npm install web3
```
2. **Connect with the Ethereum Community**:
```javascript
const Web3 = call for('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
three. **Keep track of Pending Transactions**:
```javascript
async functionality monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Implement logic to identify significant trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(error);
);
```
