Abstract: A computing apparatus, a non-transitory computer-readable storage medium, and a method of offering blockchain transactions of non-fungible tokens (NFTs) including providing a digital storefront platform for the NFTs with a mint module, configured to create and mint NFTs on blockchains, and a trade module configured to transact with the minted NFTs. A key cycler is configured to allow parallel transactions with blockchains, payment processors, the mint module, and the trade module. The key cycler includes a plurality of private keys on a web-based key management service (KMS). The key cycler is configured to facilitate transaction payments using fiat currency or cryptocurrency. Anti-money laundering (AML) and counter-terrorism financing (CTF) screening capabilities may be incorporated into the disclosed solution.
