Have you been following SatSigner, do you know what's going on with the product? The website is very sparse, and the link from above doesn't work.

I will probably sign up for the beta, but it's Nostr only...I would have to dust off my Nostr knowledge from 2 or 3 years ago.

I'm thinking of incorporating it my new book MORE Bitcoin Hands-On, if it's ready in time. From the little I know, it looks interesting.
