### Putting together a Sandwich Bot
To efficiently utilize a sandwich bot, you'll need to observe these actions:
#### one. **Comprehend the industry Dynamics**

npm install web3
```
2. **Hook up with the Ethereum Network**:
```javascript
const Web3 = demand('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Observe Pending Transactions**:
```javascript
async purpose monitorMempool()
web3.eth.subscribe('pendingTransactions', (error, txHash) =>
if (!error)
web3.eth.getTransaction(txHash).then(tx =>
// Put into action logic to determine substantial trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.error(error);
