Abstract: A self-custody wallet combination payment card includes an electronic component with storage, a processor, and a near field communications interface. Two programs are stored at the electronic component and, once provisioned, the electronic component stores one or more blockchain addresses and security keys. The two programs can include a payment application which can interface with point of sale terminals (e.g., following EMV specifications) and a crypto application which has the capability to securely store keys and return a signature for blockchain transaction.

Abstract: A method for assisting wallet providers in regulatory compliance for blockchain transactions includes: receiving, by a receiver of a processing server, a new blockchain transaction from a first computing device, the new blockchain including at least a destination address associated with a blockchain wallet as a recipient for the new blockchain transaction; generating, by a processor of the processing server, a reference identifier for the new blockchain transaction; identifying, by the processor of the processing server, a profile for the blockchain wallet based on the destination address; transmitting, by a transmitter of the processing server, the reference identifier to the first computing device; and transmitting, by the transmitter of the processing server, a notification message to a second computing device, the notification message including at least the reference identifier and data associated with the blockchain wallet.
