About Transfer

Transfer limitation

Considering that NFT is transferable which may lead to changes in relationships, we make the following restrictions in the 5Degrees protocol to minimize invalid relationships.

·l Receiver address ‘to’ must be not holding the current tokenId, or the transaction will be rolled back and export error – ‘5Degrees: already minted’

·l Sender address ‘msg.sender’ must be followed by receive address ‘to’, or the transaction will be rolled back and export error – ‘5Degrees: receiver hasn't minted sender's NFT’
