VibeSigner USB kit (NSD-S3)

A hardware Nostr signer kit: the case and the board, shipped without firmware and without keys. You flash the open-source firmware yourself — in your browser, in about two minutes — and generate your seed on the device. Nothing secret ever passes through our hands.

55 € incl. shipping ⚡ SATS ONLY SHIPS TO GERMANY checking stock…

LilyGo T-Display S3 — genuine board, ESP32-S3 with 1.9" color display
3D-printed case — fits the board and its two approve/deny buttons
Not included on purpose: firmware, seed words, USB-C cable

Why unflashed? So you don't have to trust us. The firmware is Apache-2.0 open source — read it at github.com/TuvokSeed/nsd-s3, then flash it straight from your browser at flash.flink.club. No toolchain, no drivers, just a USB-C cable and Chrome/Edge.
