To start, you'll need to be a Twitter Blue paid subscriber, which costs $3 a month in the United States. You can access the feature from Twitter's side menu to sign up. The service is also available in Australia, Canada and New Zealand.
Once you're signed up for Twitter Blue, you must access Twitter on an iPhone, as the NFT feature is currently only available on iOS. The company said NFT profile pictures will roll out to Android and the web at a later time.
Note: This is a service offered by Twitter, external to Sweet.
In the Twitter app, go to your profile (which you can access from the side menu), and you should get a notification about setting your profile picture to an NFT. To get the notification you can go to a profile of someone who already uses an NFT in this way. Now, do the following:
Tap on Choose NFT and then on Connect my wallet.
Choose the wallet that contains your NFTs, including MetaMask, Coinbase Wallet and Rainbow (if your wallet isn't available, you can't upload your NFT).
You'll be redirected to your wallet and asked to connect your wallet to Twitter.
Once the connection is made, you should see your gallery of NFTs.
Choose an NFT and then resize it as needed.
Tap on Done to add the NFT as your profile picture.
Your profile picture will now be in a hexagonal shape, indicating to others that it is a verified NFT that you own.
Note: This is a service offered by Twitter, external to Sweet. To make your NFT into a Twitter verified profile picture, you will need to send your NFT outside of Sweet. We currently do not recommend doing so as you may risk losing future utility associated with your token.
