What did you sign today?

Cool, now i also got a Name. Nostr is awesome!

nsd-s3 update (v0.0.8): the hardware signer can now erase its own key in-firmware — just a 3s hold on-device, no separate flasher needed. recover.flink.club got a real "Erase device" button plus a couple of UX fixes (scrambled keyboard, suggestion dropdown covering it).
