1. **Create Your Enhancement Surroundings**:
- Set up Node.js and npm.
- Put in Web3.js:

npm install web3
```

2. **Connect with the Ethereum Network**:
```javascript
const Web3 = involve('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```

3. **Keep track of Pending Transactions**:
```javascript
async function monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Put into action logic to establish significant trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);

);
else
console.error(mistake);

);
