# Getting Collection Slug/Symbol Before you proceed with adding a collection to the **NFT Stats** or tracking its listings and sales with the **NFT Tracker** or setting up a Specific Traits-Based Roles rule with the **Verify Roles** plugin, you first need to prepare the Collection Slug (for the collections listed on **OpenSea**) or the Collection Symbol (for the collections listed on **Magic Eden**). Technically, this is absolutely the same thing, just named differently on these two marketplaces. So let's call it Collection Slug for shot. Well, the Collection Slug is a part of the marketplace collection URL in the browser address bar, normally located after the last slash, but not always. ## Collection Slug on OpenSea.

## Collection Symbol on Magic Eden.

## Contract Address on LooksRare. The collections listed on **LooksRare** do not have a Collection Slug, and you don't need it. However, you will need the collection Contract Address, which can be found in the same way, at the end of the collection URL.

## What's next? Now, when you have your Collection Slug, you can proceed with [adding a collection](https://guide.bocto.octopeeps.com/plugins/nft-stats/adding-new-collection-with-rarible) to the **NFT Stats** or tracking a collection's listings and sales with the **NFT Tracker** or setting up a [Specific Traits-Based Roles](https://guide.bocto.octopeeps.com/plugins/verify-roles/introduction#specific-traits-based-roles) rule with the **Verify Roles** plugin.
