Sign Events Using QR Codes

[tadeubas]

Some DIY Bitcoin hardware wallets, like Krux and SeedSigner, are adding support for signing events via QR codes.

Would it be possible for nos2x to load only the npub or public key (in hex format), display the event as a QR code for signing, and then scan another QR code to import the resulting signature?

Yes, it should be possible, although it's better to fork this extension and do another dedicated to this use case, like https://github.com/lnbits/horse does for signing on a hardware device via serial. @motorina0
