Firmware Integrity

Firmware integrity refers to the assurance that the software running on a hardware wallet has not been modified or corrupted by unauthorized parties. It is the core software layer that manages the interaction between the hardware components and the user's keys.

If the firmware is compromised, the device's security guarantees are effectively nullified. To ensure integrity, manufacturers use digital signatures to verify that firmware updates come from a trusted source.

Users can also perform manual checks to verify the hash of the firmware version installed on their device. Maintaining firmware integrity is a continuous responsibility for both the manufacturer and the user.

Regular updates are necessary to patch security holes, but they must be applied from legitimate sources to avoid malicious injections. Protecting the integrity of this layer is vital for preventing remote and local exploits.
