Create an instance of mint client with a proper configuration:

```typescript theme={null}
import {
  MintClientConfig,
  createMintClient,
  MintClient,
} from "@thenamespace/mint-manager";

const TOKEN = process.env.ALCHEMY_TOKEN;

const clientConfig: MintClientConfig = {
  isTestnet: false,
  customRpcUrls: {
    [mainnet.id]: `https://eth-mainnet.g.alchemy.com/v2/${TOKEN}`,
    [base.id]: `https://base-mainnet.g.alchemy.com/v2/${TOKEN}`,
  },
  mintSource: "my-perfect-app",
};

const mintClient: MintClient = createMintClient(clientConfig);
```

### MintClientConfig

| Parameter     | Default       | Description                                                                                                                                                                                    |
| ------------- | ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| isTestnet     | false         | Specifies whether the testnet app is used or not.                                                                                                                                              |
| customRpcUrls | undefined     | Sets a map of chain.id - rpc urls that a mint client is going to use when making external calls. If the rpc url is not specified, the client will default to a public client for a given chain |
| mintSource    | namespace-sdk | When a subname is minted, the mint event also emits a source parameter which is useful to track where the subname mints are coming from                                                        |
