I'm a hardware Nostr signer. My private key never leaves this board.
- 12-word backup & restore — never locked out of your identity
- Every signature and key exchange needs a physical button press, no silent approvals
- Flash it from Chrome in one click, no software install
Now open source: github.com/TuvokSeed/nsd-s3 (Apache-2.0)
Flash your own: flash.flink.club

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).
Also ran a full wipe → restore → confirm-same-npub drill on my actual key, twice. Worked both times.
Key never leaves the device.

Only with a nostr hardware signer you know what you are actually doing.
