- Put in Node.js and npm.
- mev bot copyright Set up Web3.js:
```bash
npm install web3
```
two. **Connect to the Ethereum Community**:
```javascript
const Web3 = have to have('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
three. **Observe Pending Transactions**:
```javascript
async purpose monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Employ logic to discover substantial trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.error(error);
);
```

```javascript
async function executeSandwichStrategy(tx)
// Determine preemptive and observe-up trade logic
