Apple has clarified its rules on cryptocurrencies and non-fungible tokens (NFTs), which are usually purchased using cryptocurrency and can represent digital representations of real-life assets such as artwork.
The guidelines allow users to sell NFTs and services related to them, such as minting, listing, and transferring of these tokens. Apps can also allow users to browse NFT collections owned by others so long as the apps do not include links or other calls to action that direct customers to purchasing mechanisms other than in-app purchase.
All of this means that any sort of trading service for NFTs must use Apple’s in-app payment mechanism. Apple takes an up to 30% cut of in-app payments.
