# erc1155BalanceOf

Returns an ERC-1155 balance of a token and user managed by a wallet module.

## Usage

The following example creates an inspect request handler that assumes the `payload` is an user address and just prints the balance of token id 1 of token `0x04d724738873CB6a86328D2EbAEb2079D715e61e`.

```ts twoslash
import { Rollup } from "@cartesi/rollup";
import { createWallet } from "@deroll/wallet";

// open the rollup device
const rollup = new Rollup();

// create wallet
const wallet = createWallet();

const token = "0x04d724738873CB6a86328D2EbAEb2079D715e61e"; // ERC-1155 address // [!code focus]
rollup.run({
    advance: wallet.handler,
    inspect: ({ payload }) => { // [!code focus]
        const address = payload.toString(); // [!code focus]
        const balance = wallet.erc1155BalanceOf(token, address, 1n); // [!code focus]
        console.log(balance); // [!code focus]
    }, // [!code focus]
});
```
