import { createWallet } from "@deroll/wallet";

// create app
const app = createApp();

// create wallet
const wallet = createWallet();

app.addAdvanceHandler(wallet.handler);

app.addInspectHandler(async ({ payload }) => { // [!code focus]
    const address = payload.toString(); // [!code focus]
    const balance = wallet.etherBalanceOf(address); // [!code focus]
    console.log(balance); // [!code focus]
}); // [!code focus]
```
