A system and associated methods display on a user device a non-fungible token (NFT) in an application that displays video data. The methods include storing the NFT of a user in a database accessible to the application, associating an ID of the user for the application to the NFT, and receiving a selection of the NFT during use of the application. Upon selection, the selected NFT is provided to the user device for superimposing the selected NFT over the user's face, providing the selected NFT as a background image for the video data on the user device, or both. The user device includes a web application that connects the database to a crypto wallet containing the NFT. The NFT may be processed to crop out the eyes and mouth of the NFT for registration with the user's eyes and mouth when the NFT is superimposed over the user's face.
