Non-fungible token document platform

A method comprising:

• verifying an identity of a requestor using one or more backend services of a host platform via at least one processor, the requestor indicating to a frontend of the host platform via a user platform to generate a signature smart contract usable by the requestor as a digital signature;
• generating the signature smart contract using the one or more backend services of the host platform via the at least one processor;
• generating a signature non-fungible token (NFT) using the one or more backend services of the host platform via the at least one processor;
• storing the signature smart contract and the signature NFT on a blockchain using the one or more backend services of the host platform via the at least one processor;
• and
• adding a signature transaction to at least one block on the blockchain associated with the signature smart contract and the signature NFT using the at least one processor in response to receiving a sign request from the requestor received via the frontend of the host platform from the user platform, the sign request indicating to use the signature smart contract and the signature NFT to digitally sign for the requestor using the digital signature.

A method comprising:

• receiving at a frontend of a host platform from a user platform a request for a check to generate using at least one processor, the request specifying check information including funds and a funds source for the check;
• withdrawing the funds for the check from the funds source using one or more backend services of the host platform via the at least one processor;
• generating a non-fungible token (NFT) and an associated smart contract for the check using the one or more backend services of the host platform via the at least one processor;
• storing the NFT and the associated smart contract on a blockchain using the one or more backend services of the host platform via the at least one processor;
• recording at least a portion of the check information including the funds in at least one of the NFT, the associated smart contract, or at least one block on the blockchain using the one or more backend services of the host platform via the at least one processor;
• associating the NFT with a token wallet using the one or more backend services of the host platform via the at least one processor;
• receiving a request associated with redeeming the check using the one or more backend services of the host platform via the at least one processor;
• and
• providing a response to the request associated with redeeming the check via the frontend of the host platform based at least on the NFT.
