#### one. **Understand the marketplace Dynamics**
- **Analyze Market place Circumstances**: Understand the volatility and liquidity in the property you’re focusing on. Higher volatility and small liquidity can generate a lot more sizeable value impacts.
- **Know the DEXs**: Distinctive DEXs have various cost structures and liquidity swimming pools. Familiarize yourself Along with the platforms where you program to work your bot.

npm install web3
```
2. **Connect with the Ethereum Network**:
```javascript
const Web3 = demand('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
```
3. **Monitor Pending Transactions**:
```javascript
async perform monitorMempool()
web3.eth.subscribe('pendingTransactions', (mistake, txHash) =>
if (!mistake)
web3.eth.getTransaction(txHash).then(tx =>
// Put into action logic to establish large trades
if (isLargeTransaction(tx))
executeSandwichStrategy(tx);
);
else
console.mistake(error);
);
```
4. **Put into action the Sandwich Method**:
```javascript
async operate executeSandwichStrategy(tx)
// Determine preemptive and follow-up trade logic

await web3.eth.sendTransaction(preTrade);
await web3.eth.sendTransaction(followUpTrade);
functionality isLargeTransaction(tx)
// Define criteria for a big transaction
return tx.price && web3.utils.toBN(tx.benefit).gt(web3.utils.toBN(web3.utils.toWei('one', 'ether')));
```
