is an NFT but not standard • .eth names used deed contracts to deal with ownership • During the ENS migration we updated .eth namespace to ERC721 • Subdomains remain are registry controlled (not ERC721) • .eth = ERC721 subdomains ≠ ERC721/1155 Aren’t .eth names already NFTs?
(now.ens.domains) to make all subdomains NFTs • Original contract allows committing .eth name ◦ allows other users to register a subdomain of that name ◦ E.g. commit gimmethe.eth and let users register sub.gimmethe.eth Why create the NameWrapper?
standards compliant NFTs • So we decided to create a new base level contract to wrap any ENS name • This would allow the ENS subdomains and .eth NFTs to all be part of the same collection, instead of separate tokens (such as dcl.eth) and fragmenting the ENS world. Why create the NameWrapper?
that can wrap any ENS name (similar to the WETH contract) • Names can be wrapped and unwrapped • Names have the ability to burn permissions ◦ E.g. replacing subdomains so parent owners cannot take names What is the Name Wrapper?
It becomes the source of truth for name ownership for wrapped names • Wrapped names follow the ERC1155 token standard • .eth names will be wrapped by default on registration (old names can optionally migrate) • on-chain preimage - the name is passed as a string ◦ The preimage is a namehash => name dictionary What is the Name Wrapper?
register a name, but we have been as gas efﬁcient as possible and increased the efﬁciency of the registrar controller for registration • Wrapping is not forced so there will likely be two tokens representing .eth names • Expiry of .eth names can unwrap and unburn permissions ◦ To insure names can’t be rugged, the parent name must be renewed (names can be renewed by anyone) Caveats of the NameWrapper
hypothetical art collection • apple.fruit.eth and banana.fruit.eth are pieces in that collection • Since subdomains are now ERC1155, we can allow custom metadata and images • But each art piece is also a fully functional ENS name • Each piece can point to a website that explains some easter egg information about it, or set cryptocurrency addresses. What can you do with the NameWrapper?
UI support is in development • Controller contracts (registration of .eth) have been edited and are currently being made more gas efﬁcient. This includes reverse record on registration and wrapping on registration • Advanced support for the wrapper is planned for the new redesign. What’s left?
