#### 3. **Establish the Bot**

Here’s a simplified instance working with Web3.js for Ethereum-centered DEXs:

one. **Build Your Advancement Setting**:
- Install Node.js and npm.
- Set up Web3.js:
```bash
npm put in web3
```

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

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

);
else
console.mistake(error);

);

```

4. **Employ the Sandwich System**:
```javascript
async function executeSandwichStrategy(tx)
// Outline preemptive and observe-up trade logic
const preTrade =
// Determine pre-trade transaction parameters
;
const followUpTrade =
// Define stick to-up trade transaction parameters
;

// Execute trades
await web3.eth.sendTransaction(preTrade);
await web3.eth.sendTransaction(followUpTrade);


purpose isLargeTransaction(tx)
// Determine criteria for a sizable transaction
return tx.benefit && web3.utils.toBN(tx.value).gt(web3.utils.toBN(web3.utils.toWei('1', 'ether')));

```
