Self-Destruct Mechanism (Pro-only)
The Keystone’s design limites the only point of physical entry to a Micro SD card slot, which is used for firmware updates. An attacker would need to disassemble the Keystone in order to carry out a side-channel attack. The self-destruct mechanism in the Keystone Pro is designed to detect disassembly, and will automatically wipe all information including the private keys upon detection. If your self-destruct mechanism is triggered, the device will be bricked, but you can recover your assets using your recovery phrase.
The lifespan of self-destruct mechanism components may not exceed 2 years.
