Abstract
A method for performing dual verification to combine a non-fungible token (NFT) with a digital payment instrument includes: receiving a first set of authentication credentials and a second set of authentication credentials, the first including a transaction account identifier, and the second set including an NFT identifier and a public key of a cryptographic key pair; performing a first verification process using the first set of authentication credentials based on at least a comparison of the first set of authentication credentials with data associated with a transaction account identified using the transaction account identifier; performing 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 the NFT identifier; and transmitting a result of the first verification process and the second verification process to a computing device.
