How to use RNS domains with non-fungible token standards? (such as ERC721)

Question

I have registered a .rsk domain using RNS, and am wondering if I can transfer ownership of it to other accounts, like an NFT.

Is this possible with domains and subdomains? If so how?

Answer 1

All the domains that are created with the new FIFS Registrar, or migrated using migrate from auction are ERC721 compatible.

(Note that the above only applies to domains; subdomains are not tokenised, and not ERC721 compatible.)

The following are the relevant lines of code within the RNS smart contracts:

FIFSRegistrar --> (inherit) FIFSRegistrarBase --> (property) NodeOwner --> (inherit) ERC721 --> (property) tokenId

Details

(inherit) FIFSRegistrarBase in FIFSRegistrar.sol#L9

contract FIFSRegistrar is FIFSRegistrarBase, PricedContract {

(property) NodeOwner in FIFSRegistrarBase.sol#L27

    NodeOwner nodeOwner;

(inherit) ERC721 in NodeOwner.sol#L9

contract NodeOwner is ERC721, Ownable, AbstractNodeOwner {

(property) tokenId in NodeOwner.sol#L113

        uint256 tokenId = uint256(label);
