Namebase domains are Handshake names minted onto Ethereum as non-expiring ERC-721s. MetaMask cannot resolve them on its own: it asks the ENS registry, which has never heard of them. This snap knows where to look instead. It talks to no server. Whatever a name resolves to is where the user's money goes, so it is read from the chain through the user's own provider - which is also why no network permission is needed. addr() falls back to whoever holds the token, so a name keeps paying the right person after a sale. The manifest declares chains only and carries no TLD list, so enabling minting on a new TLD needs no change here. Two rules in src/index.ts filter instead: stay out of TLDs another naming system is authoritative for, and ignore anything without two labels. When in doubt the answer is null, never an address. Hashing mirrors the registry's dsld_node() and every test vector is generated from it. Two requirements are pinned because breaking either is silent: UTS-46 must be transitional, and it must not be ENSIP-15. Either mistake yields a valid-looking node with no records and a name that never resolves. The built bundle is tested separately from the source because tr46 reaches for the Node punycode builtin - without that polyfill the build is clean and every non-ASCII name fails at runtime.
