Is it yours?

Prove you control one of its domains or wallets. A proven owner passes the owner check, and can reply beside the evidence on its page. Proving control changes no other check: those come from what addrbook observes.

It has no endpoint on a public domain and no wallet addrbook knows of, so there is nothing to prove control of yet. Once its listing names an endpoint or a wallet, come back.

How claims work · Claims are free. addrbook never asks for a private key, a seed phrase or a payment.
