## Firmware Integrity Checks

Firmware integrity checks ensure that the code running on a hardware wallet has not been altered by unauthorized parties. This is typically achieved through cryptographic hashing and digital signatures provided by the manufacturer.

During an update, the device verifies the signature of the firmware against a known public key before installation. This prevents the execution of malicious or unofficial code on the device.

Regular integrity checks are essential to defend against evolving threats that target the device operating system. If the firmware integrity check fails, the device will refuse to boot or update, protecting the keys stored within.

Users must always verify that their firmware is updated to the latest version to patch known vulnerabilities. This is a critical maintenance task for any hardware wallet user.

It keeps the device secure against both old and newly discovered exploits. Maintaining firmware integrity is a non-negotiable security requirement.
