1. **Create Your Improvement Atmosphere**:
- Put in Node.js and npm.
- Install Web3.js:
```bash
npm put in web3
```
2. **Hook up with the Ethereum Community**:
```javascript
const Web3 = call for('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Watch 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 identify massive trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(mistake);
);
```
4. **Apply the Sandwich Strategy**:
```javascript
async operate executeSandwichStrategy(tx)
// Outline preemptive and follow-up trade logic

// Determine pre-trade transaction parameters
;

await web3.eth.sendTransaction(preTrade);
await web3.eth.sendTransaction(followUpTrade);
perform isLargeTransaction(tx)

- **Simulate Trades**: Test a variety of situations to discover how your bot responds to diverse marketplace conditions.
#### 5. **Deploy and Check**
- **Deploy on Mainnet**: The moment tests is complete, deploy your bot on the mainnet.
