#### 3. **Acquire the Bot**
Here’s a simplified instance applying Web3.js for Ethereum-primarily based DEXs:
one. **Set Up Your Advancement Natural environment**:
- Put in Node.js and npm.
- Install Web3.js:
```bash
npm set up web3
```
two. **Hook up with the Ethereum Network**:
```javascript
const Web3 = demand('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
three. **Keep track of Pending Transactions**:
```javascript
async functionality monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Carry out logic to discover huge trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(error);
);
```
4. **Put into practice the Sandwich System**:
```javascript
async perform executeSandwichStrategy(tx)
// Outline preemptive and observe-up trade logic
