Twitter recently on January 20th, 2022 added NFT Profile pictures for Twitter Blue subscribers. PFPs (profile pictures) that are NFTs are shown in a Hexagon shape. When clicked on it shows the NFT, the collection it belongs to, attributes, and other interesting statistics.

Sadly for us Tezos and CleanNFT fans Twitter has only integrated with Ethereum NFTs as of now. With more integration and push towards clean digital artwork I’m sure we will see Tezos and other blockchains getting added to the site.
