A method for managing access to cryptocurrency assets includes: protecting cryptocurrency assets using a first security protocol in which signatures generated from multiple cryptographic keys are required to access a cryptocurrency address. Each of the multiple cryptographic keys are stored by one of a plurality of computing devices. The method includes receiving a user request to exit the first security protocol; authenticating the user request to exit the first security protocol; and in response to authenticating the user request, exiting the first security protocol, including transporting a descriptor for the multiple cryptographic keys to a single one of the plurality of computing devices. The descriptor enables access to the cryptocurrency address.

Cryptocurrency access management

A system for locally authenticating a transaction of digital financial assets, such as cryptocurrency. A first device may locally store financial assets in non- volatile memory of the first device. The first device may use the locally-stored financial assets to conduct a local transaction with a second device. The first device may generate a transaction settlement data token and exchange the token with the second device, wherein the transaction settlement data token includes information specific to the local transaction, a value associated with the local transaction, and encrypted personal information associated with the first device. After receiving a confirmation of transmission from the second device, the value associated with the local transaction may be debited from the locally-stored financial assets.
