a client device comprising a processor and a memory; and
machine-readable instructions stored in the memory that, when executed by the processor, cause the client device to at least:

generate a key-pair comprising a private key and a public key;
transmit the public key and the one or more identity credentials to the token issuer system; and
receive a token address from the token issuer system, the token address corresponding to a location of the non-fungible token on a distributed ledger.
