Traits

NonFungibleTokenApproval

Trait used when it’s desired to have a non-fungible token that has a traditional escrow or approval system. This allows Alice to allow Bob to take only the token with the unique identifier “19” but not others. It should be noted that in the core non-fungible token standard there is a method to do “transfer and call” which may be preferred over using an approval management standard in certain use cases.

NonFungibleTokenApprovalReceiver

Approval receiver is the trait for the method called (or attempted to be called) when an NFT contract adds an approval for an account.
