Summary

The COLDCARD utilizes specialized Microchips, ATECC608, and Maxims DS28C36B to secure its vital data, serving as a True Air-gap device designed for a complete life cycle. This hardware wallet ensures that only signing activity is recorded, providing total isolation during the critical phases of seed generation and transaction signing. The core function relies on the 24-word seed phrase, which is meticulously stored on these secure components. Users can access this information via a dedicated screen or a USB drive, but they cannot connect directly to a computer. The security guarantees that the critical master secret is never exposed to external threats or user-controlled devices, maintaining a robust physical barrier to unauthorized access throughout the wallet's lifespan.
