Written by UKey Wallet

When using a hardware wallet, it is crucial to ensure the security of firmware and software updates.

Code review:Our code has been reviewed by professional security teams (such as SlowMist, OffsideLabs) to ensure there are no backdoors.

The build process is transparent:UKey's hardware firmware and software code are fully open source and available on GitHub, where you can view the specific details of each update.

Verify when upgrading:When the hardware wallet firmware is upgraded, UKey Wallet will perform digital signature verification on the new version to ensure the source and integrity of the upgrade.

Private key security:The security chip (or "secure element") in the UKey hardware wallet is always offline during use.
