Method and system for activating wallet private keys through blockchain addresses

A system for registration of an identified blockchain wallet using a payment card, comprising:

• an activation server;
• a computing device;
• and
• one of:
• an integrated circuit payment card and a financial application program, wherein
• the computing device includes
• a receiver
• receiving payment details for a payment card issued to a consumer for a transaction account, the payment details including at least a card identifier, wherein the payment details are received from the integrated circuit payment card or the financial application program, and
• receiving wallet details for a blockchain wallet, the wallet details including at least a wallet identifier,
• a transmitter transmitting a new blockchain wallet generation request to one of the:
• integrated circuit payment card and the financial application program, and
• a processor,
• wherein one of the integrated circuit payment card and the financial application program (i) creates the new blockchain wallet by generating a cryptographic key pair, and (ii) upon creating the new blockchain wallet, disables the new blockchain wallet such that the new blockchain wallet is unable to be used until an activation instruction is received,
• wherein the transmitter, of the computing device further (i) transmits at least the card identifier and the wallet identifier to an activation server, wherein the activation server stores an association between the wallet identifier and the transaction account, and (ii) transmits an activation message to the computing device,
• wherein the receiver of the computing device further receives the activation message from the activation server,
• wherein the processor of the computing device, in response to receiving the activation message, generates an unlock instruction for unlocking the new blockchain wallet;
• wherein the transmitter of the computing device further transmits the unlock instruction to the integrated circuit payment card or the financial application program;
• and
• wherein, in response to receiving the unlock instruction, at least one of the integrated circuit payment card and the financial application program unlocks the new blockchain wallet, enabling use of a private key of the cryptographic key pair associated with the blockchain wallet for use in blockchain transactions.
