#### 3. **Build the Bot**
Right here’s a simplified example working Front running bot with Web3.js for Ethereum-dependent DEXs:
one. **Build Your Growth Surroundings**:
- Set up Node.js and npm.
- Install Web3.js:
```bash
npm install web3
```
2. **Connect to the Ethereum Community**:
```javascript
const Web3 = need('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Observe Pending Transactions**:
```javascript
async operate monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Carry out logic to detect large trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(mistake);
);
```
4. **Employ the Sandwich Strategy**:
```javascript
async functionality executeSandwichStrategy(tx)
// Determine preemptive and observe-up trade logic
