# Collectibles OpenSea-Based Roles
This rule type allows you to assign a specific role to your **Discord** users, regardless of the number of NFTs from a specific **Collectibles type NFT collection** they own. Almost identical to the [**Collectibles Contract-Based Roles**](/plugins/verify-roles/verification-rules/collectibles-contract-based-roles.md) rule, but it operates via an **OpenSea** [collection slug](/appendix/getting-collection-slug-symbol.md), which makes this rule type work with the collections based on any chain supported by **OpenSea**.
## Explanation of the Fields.
* In the **Rule Name** field, enter your desired rule name.
* In the **Blockchain** dropdown, select the blockchain where your collection contract is deployed.
* In the **Collection Slug** field, enter the [collection slug](/appendix/getting-collection-slug-symbol.md).
* In the **Role** dropdown, select the prepared **@Role** you wish to assign to the holders.
{% hint style="danger" %}
If you set up the **Editions** collection type instead of the **Collectibles** type, no error will occur, but the rule won't work!
