Reverse look up


If you know the public key of a domain name registry and want to get the human readable name, you need to perform a reverse lookup.

The following code can be used to resolve the domain name from its public key:

import { reverseLookup } from "@bonfida/spl-name-service";

// Public key of bonfida.sol
const domainKey = new PublicKey("Crf8hzfthWGbGbLTVCiqRqV5MVnbpHB1L9KQMd6gsinb");

const domainName = await reverseLookup(connection, domainKey); // bonfida
