Nip-26 “Delegated Event Signing” seems to be the closest way to implement such a feature. @fiatjaf had something to say a while back about this NIP having the potential to force its usage onto all of Nostr, but I cannot find the article. As a result, however, delegated event signing (using this nip) has fallen out of vogue. I do believe nos2x still implements it? Not sure what other signers or clients also do …

Here’s the spec:

 Thank you.
