U.S. Patent 10554401 was awarded to CRYPTO MINT INC. on February 04, 2020 and is entitled “Multi-address population based on single address.” The first named inventor is Bobby Christopher Lee of Las Vegas, NV. The abstract contains an overview of the patent disclosure:

A physical card (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for digital bearer assets. The physical card may include disposed thereon a single address operable to receive digital bearer assets in one or more transactions on a decentralized computing platform, like a blockchain-based decentralized computing platform. Other decentralized computing platforms utilize different address generation protocols, thus preventing use of a single address on those other platforms. A set of addresses is generated, each address corresponding to a given decentralized computing platform. Each address is based on a same underlying key-pair, and a primary address is selected from the set for a given card. The remaining addresses in the set are stored, without storage of the public key or private key, and returned in a response to a request for additional addresses of the currency card.
