1. **Put in place Your Progress Ecosystem**:
- Put in Node.js and npm.
- Set up Web3.js:
```bash
npm install web3
```
2. **Connect to the Ethereum Network**:
```javascript
const Web3 = call for('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
three. **Watch Pending Transactions**:
```javascript
async purpose monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Put into practice logic to detect significant trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(error);
);
```
4. **Apply the Sandwich Technique**:
```javascript
async perform executeSandwichStrategy(tx)
// Define preemptive and adhere to-up trade logic
const preTrade =
// Define pre-trade transaction parameters
;

;
// Execute trades
await web3.eth.sendTransaction(preTrade);
await web3.eth.sendTransaction(followUpTrade);
operate isLargeTransaction(tx)
// Define requirements for a sizable transaction
return tx.value && web3.utils.toBN(tx.benefit).gt(web3.utils.toBN(web3.utils.toWei('one', 'ether')));
```
