Firmware Open Source

Cobo Vault has pioneered the hardware wallet industry’s first open source Secure Element firmware. It allows you to see how private keys are derived from physically generated entropy (TRNG) and stay entirely confined within the Secure Element. Our hardware wallet application layer, device schematic (circuit diagram), and bill of materials (BOM) are also open source, soon to be followed by our operating system layer code.

Why MicroSD Card Firmware Upgrades?

In creating a truly air-gapped hardware wallet, we had to eliminate USB ports.

Firmware upgrades add support for more coins and staking services and may also add features or enhance the user experience.

If you firmware version is below V1.0.5, please upgrade to V1.0.5 before upgrading to the latest version. Download V1.0.5
