Abstract: A computer-implemented system and method uses a processor of a device of an expiring virtual currency (EVC) wallet user. An EVC transaction is retrieved that is associated with a blockchain and addressed to an address associated with the EVC wallet. The EVC transaction comprises an expiration date for the EVCs, as part of virtual currency user rules (VCURs). If the expiration date of the EVCs has passed, the method automatically, and without user intervention, transfers the EVCs to a transferee designated in the VCURs.
