The social media giant Twitter has taken further tentative steps into the world of Ethereum (ETH) and non-fungible tokens (NFTs) – by moving to allow some users to use verified NFTs as their profile pictures. And the firm has also apparently created an account on the invite-only ethereum-based NFT marketplace Foundation.

Per an official tweet from the Twitter subscription arm Twitter Blue and a new page on its website, users of the service, which costs USD 2.99 per month, will be able to “set an NFT as their profile picture from the Twitter for iOS app” – which means they must be Apple iPhone users, although this will mean a special “verified” “hexagon-shaped profile picture” can be “seen across all platforms.”
