Apple has updated the App Store guidelines for descriptions that match iPhone and iPad apps.
Now you can sell NFTs (non-fungible tokens) in iOS apps, but only through the Apple payment system. For each purchase, the company will charge a commission of 30%. It is prohibited to reconfigure users on the site to purchase NFTs.
To the point: What is NFT. Why does no one remember before?
Developers cannot use NFT as an in-app payment method. Also, NFT should not act as a mechanism for unlocking additional features in the application.
There are applications only for buying and distributing NFTs.
