Is it going to have to pop up the sheet for every event that needs signing? I’m not opposed to accepting a PR to support it but the only people asking for this are Nostr devs who don’t want to trust the code of other Nostr devs. I don’t think anyone who isn’t already self-custodying their crypto will use it. We’ve never had a user come to us and say they won’t use @nos because we store the keys in Apple’s keychain. Would it be nice to have an option for an Amber like solution for iOS, sure. But I doubt it’ll get much use. Kind of like how it’s great Signal is open source, but there isn’t much anyone can or does do with the source.
