Abstract
The present disclosure generally relates to methods, systems, apparatuses, and non-transitory computer readable media for managing cryptocurrency. A cryptocurrency management system has a cryptocurrency management device (CMD), a mobile communication device (MCD), and a cryptocurrency management server (CMS) that are each configured to store a respective private key for use in generating a respective authenticating signature for a multi-signature address of a cryptocurrency network. Any two of the three authenticating signatures capable of being generated by the CMD, MCD, and CMS may be combined to generate a fully authenticated request for transferring cryptocurrency associated with the multi-signature address. The system provides the user with a flexible self-custody solution that permits him or her to transfer cryptocurrency without having to access the private key stored at the CMS. However, the CMS enables for recovery in the event of loss or unavailability of one or both of the CMD and/or the MCD.
