## 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.

## MintTransfer method:

If you're using `typescript` code examples in methods page, before every example use this code here to prepare your provider to web3, ethereum wallet, smart-contract instance and abi.
{% endhint %}

<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(
    "wss://eth-sepolia.g.alchemy.com/v2/ATnZ4...." // provider
);

const signer = new ethers.Wallet(
  "aab5433a31f1bb3e...", // your ethereum wallet private key
  provider
);

const res = await axios.get(
  "https://cdn.stagemeta.dev/contracts/2.0.0.json" // StageMeta smart-contract contract abi
);
const abi = JSON.stringify(res.data);
const inter = new utils.Interface(abi);

const stageMetaContract = new ethers.Contract(
  "0x4b39ceb401769e3e...", // StageMeta smart-contract address
  abi,
  signer
);
