So you're okay for one client to do this, but not okay for another client to do it? Yikes.
Nostr key custody should be a test bed for bitcoin key management. Anything unique outside of “we just hold the keys”? What’s the trade off gained technically?
Oh I understand it. I just like pushing your buttons. Remember when you said that clients could post for you if they managed your keys... How is that different here? Alex could fake a post and we'd never know unless we went and looked on Mastodon to confirm it. That's a lot of work that 99% of people aren't going to do, because we're trying Alex. Your move.
How many clients do this now?
