# Rarity ranks

Since version 0.3.0, Labs also support rewards based on rarity ranks from [CNFT.tools](https://cnft.tools/).

{% hint style="danger" %}
**Very important**

If you want to configure rewards based on rarity ranks you will need to ensure:

1. All your policies rarity ranks should be tracked by CNFT.tools.
2. You must DM our team so we can properly register the rarity ranks in our system. 
   {% endhint %}

After you ensure the above points have been properly set, you can then configure your stake rewards using rarity ranks
