1. **Create Your Advancement Setting**:
- Install Node.js and npm.
- Install Web3.js:
```bash
npm install web3
```
2. **Hook up with the Ethereum Network**:
```javascript
const Web3 = need('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
three. **Check Pending Transactions**:
```javascript
async function monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Apply logic to identify substantial trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.error(error);
);
```
four. **Put into action the Sandwich Method**:
```javascript
async functionality executeSandwichStrategy(tx)
// Outline preemptive and adhere to-up trade logic
const preTrade =
// Determine pre-trade transaction parameters

await web3.eth.sendTransaction(preTrade);
await web3.eth.sendTransaction(followUpTrade);
function isLargeTransaction(tx)
// Determine standards for a substantial transaction
return tx.worth && web3.utils.toBN(tx.value).gt(web3.utils.toBN(web3.utils.toWei('one', 'ether')));
```

- **Simulate Trades**: Test a variety of eventualities to find out how your bot responds to unique market problems.
#### 5. **Deploy and Monitor**
- **Deploy on Mainnet**: After screening is finish, deploy your bot on the mainnet.
