I like this idea of “verified local key encryption”. Though this may be difficult to verify, having NIP49 implementation baked into a library will like NDK (so client code doesn’t NEED to handle the nsec at all) will be a good start.

 Yes!
I'm not a dev and so I might be naive on the feasabilty of the verification. But it's the best trade of I can come up with for now. It works cross-platform and has way better trade offs than bunkers etc...  

 I’m with you on this… but we prolly gonna need more peeps interested if we’re gonna make “Key Encryption Great Again”. LMK how you fare.  

 Will do 🫡
