Vitrum

Vitrum is a fully open-source hardware crypto wallet (cold wallet) designed by Logitale, built on an STM32 microcontroller paired with the TROPIC01 secure element. Private keys never leave the device: every transaction is displayed in plain sight on the monochrome screen — amount, destination address, network fee — then confirmed with a physical press on a dedicated button, out of reach of a compromised machine. Directional pad navigation, separate backlit accept and reject buttons, USB-C for connection and power. There is no battery at all — nothing to charge, nothing to age or swell; a single coin cell keeps tamper detection armed while the device is unplugged. Both hardware and firmware are open and auditable: security rests on code anyone can verify, not on a black box.
