# Configure Viem

Make sure to include in your chain configuration the correct addresses. 

{% hint style="warning" %}
Please import Berachain Mainnet directly from viem (**not from wagmi**). Directly use the viem directives like "getEnsName" and "getEnsAddress"
{% endhint %}

```jsx
contracts: {
  ensRegistry: {
    address: '0x5b22280886a2f5e09a49bea7e320eab0e5320e28',
  },
  ensUniversalResolver: {
    address: '0xddfb18888a9466688235887dec2a10c4f5effee9',
  },
}
```

### Special Characters

If your name contains special characters it may not resolve correctly due to ENS/viem standards.

It is still possible to mint, but there may be problems in resolving – we do not recommend using Beranames in these case for sending / receiving funds.
