If you've created a collection outside of Rarible (via your own smart contract or another NFT platform), you can claim it on Rarible to edit its collection page, add your social links and more.
Here's how it works:
Step 1: Navigate to your collection.
Step 2: On the collection page, click on the three dots below the collection's description and then click on "Claim ownership."
Step 3: Rarible will identify whether your wallet address created the collection or not (if this step fails, make sure you're logged in with the correct wallet).
Step 4: If you're logged in with the correct wallet, simply follow the steps to manage your collection page on Rarible.
If you are still unable to claim a collection that you rightfully own, please contact our support team via: https://rariblecom.zendesk.com/hc/en-us/requests/new or send us an email via: email@example.com
