Please see What cards does ALT support? To determine if your card type is not supported at this time.
You have a few options if circumstances differ from unsupported assets:
ALT provides our customers the important ability to vault assets and do more with their collection. When you send your cards to the Vault, they will be professionally photographed, valued, and automatically uploaded to your portfolio.
Please send the card details you would have entered using the supported messenger located at the bottom right of your screen or reach out to firstname.lastname@example.org., and we will assist in getting your card uploaded.
