## Check mintTransfer method:

The `checkMintTransfer()` is a `public` method that allows users to check whether the given TPA names are available for purchase or have already been minted.

<pre class="language-typescript"><code class="lang-typescript"><strong>import axios from "axios";
</strong>import { ethers, providers, utils } from "ethers";

const provider = new providers.WebSocketProvider(

const signer = new ethers.Wallet(

const abi = JSON.stringify(res.data);
