Use extended profile fields¶

Extra profile fields share the same kind-0 event as the name and bio. You can access them through Nip24ExtraMetadata, which inherits the usual profile metadata methods.

For new code, use Nip01.fetch and Nip01.update. The older Nip24 helper is deprecated; you may still encounter it in code like this:

Nip24ExtraMetadata meta = Nip24.fetch(pool, pubkey).await();

// ... read or change fields, NIP-01 style ...

List<AsyncTask<NostrMessageAck>> acks =
    Nip24.update(pool, signer, meta).await();

You can also convert between the two representations:

Nip24ExtraMetadata fromMetadata = Nip24.from(nip01metadata);
Nip24ExtraMetadata fromEvent = Nip24.from(sourceEvent);

To associate the profile with accounts on other services, see external identities.
