Embodiments of the present invention provide a system for secure transfer of encrypted resources and asynchronous execution. In general, a user initiates an event with a merchant system and requests a secure resource transfer process associated with the event. Encrypted initial event details are transmitted through an asynchronous command form the merchant system to a computing device of the user, and resource information is identified at the computing device of the user. The computing device of the user then transmits the event details and the resource information to an event processing system for final execution.
