Method and system of associating custom card designs with non-fungible tokens

A method for performing dual verification to combine a non-fungible token (NFT) with a digital payment instrument, comprising:

• receiving, by a receiver of a processing server, a first set of authentication credentials and a second set of authentication credentials, the first set of authentication credentials including at least a transaction account identifier, and the second set of authentication credentials including at least an NFT identifier and a public key of a cryptographic key pair;
• performing, by a processor of the processing server, a first verification process using at least the first set of authentication credentials based on at least a comparison of one or more values included the first set of authentication credentials with one or more values associated with a transaction account identified using the transaction account identifier;
• performing, by the processor of the processing server, a second verification process using at least the second set of authentication credentials based on validation of a digital signature using the public key, the digital signature being identified using at least the NFT identifier;
• and
• transmitting, by a transmitter of the processing server, a result of the first verification process and a result of the second verification process to a computing device.
