I gave nostr:npub18s4zkd0wjq5gkthz4paw2704ty4s354wcp2krvxy0sewz3g9z2cs73ydrt a try, here's an overview:

- Requires a proton email to login and decrypt wallet data client side

- Smooth onboarding/wallet creation

- Overall, very clean/intuitive UX

- Multi wallet support, each with their own settings (currency,etc...)

- Bitcoin via email can be disabled

- Display your 12 words seed phrase (no clipboard copy/seed qr) and import in other wallet should work

- Receive, send and buy (3rd parties)

- You can force-generate receive address

Overall, very well executed.

I wished there was a native application instead of a PWA, but it's still early.

Congrats to the team!!!
