Abstract
A phone case includes a cold wallet that holds various cryptocurrencies. A method provides for operation of a smartphone placed in the phone case to interact with the cold wallet. The cold wallet can be incorporated into a system that includes secure storage, a battery, and communications hardware. The system has robust security features, including features that require surface to surface proximity. For example, the system may use wireless charging, which only operates with a limited range. The phone case can use the wireless charging system to send and receive authentication signals from the smartphone. Based on the authentication signals the phone case can power up and connect the secure storage to the rest of the system, thereby only providing secured access to the keys in the cold wallet. After use, the system disconnects the secure storage and the powers down to cold wallet, protecting the private keys.
