Abstract
A system for managing and using digital financial assets, such as cryptocurrency uses multiple independent devices that mutually cooperate to control cryptocurrency assets in a secure manner. Each of these devices may store a unique private key associated with the cryptocurrency assets, which may be configured such that a certain minimum number of these private keys are required to transfer the cryptocurrency assets. The use of multiple private keys spread across multiple distinct devices may reduce the likelihood of loss stemming from a hardware failure or reduce the likelihood of an attacker successfully gaining access to the cryptocurrency assets. In addition, selection of the devices to be used for storing these private keys, as well as how many private keys are required to authorize a transaction, may be tailored to balance a user's preferences for reliability of access versus security and for third-party custody versus self-custody.
