You can create exclusive content for your NFT two ways.
You can add exclusive content when you are creating your NFT on Cent. In the first step of creating your release on Cent Pages you will see an option to attach Exclusive Content below the post editor.
You can add exclusive content to your NFT after it has been created. When you go to manage your releases in your Cent Portal you can click into the release you’d like to add exclusive content to. You will see a button to create exclusive content for that release. You can create multiple pieces of exclusive content for the same release.
