Systems and methods of converting payment protocols, including: sending a transaction request to a computing device, wherein the transaction request is associated with a first protocol, determining based on the received transaction request, a type of the first protocol, determining a second protocol, wherein the type of the second protocol is determined based on the received transaction request, determining a characteristic of the received transaction request, and converting the received transaction request from the first protocol into the second protocol, wherein the conversion is carried out based on a predefined conversion protocols database.

A method for assisting wallet providers in regulatory compliance for blockchain transactions includes: receiving, by a receiver of a processing server, a new blockchain transaction from a first computing device, the new blockchain including at least a destination address associated with a blockchain wallet as a recipient for the new blockchain transaction; generating, by a processor of the processing server, a reference identifier for the new blockchain transaction; identifying, by the processor of the processing server, a profile for the blockchain wallet based on the destination address; transmitting, by a transmitter of the processing server, the reference identifier to the first computing device; and transmitting, by the transmitter of the processing server, a notification message to a second computing device, the notification message including at least the reference identifier and data associated with the blockchain wallet.

In one embodiment, a method includes receiving information associated with a project for creation of digital content and generating an object including the received information, where the object is stored by a social-networking system. The method also includes causing a data item associated with a blockchain network to be generated and deployed to the blockchain network, where the data item is generated based on the information associated with the project that is included in the object, is associated with a type of token recorded in a blockchain associated with the blockchain network, and includes instructions executable according to a protocol associated with the blockchain network. The method further includes collecting information associated with the data item from the blockchain and updating the object based on the collected information.

An apparatus has a processor and a network interface circuit connected to the processor to provide connectivity to networked machines. A memory is connected to the processor. The memory stores instructions executed by the processor to establish a first network connection to a first proprietary block chain to obtain first non-fungible token (NFT) attributes associated with a first public key. A second network connection is created to a second proprietary block chain to obtain second NFT attributes associated with a second public key. A third network connection with a client machine supplies the first NFT attributes and the second NFT attributes.

A cryptocurrency system [a] One or more Creator Computing Devices, [b] One or more Asset-Backed Computing Devices, [c] One or more Initial Transaction Computing Devices, [d] One Certifier Entity employing a Certifier Computing Device, and [e] One or more Block-Chain Verifier Computing Devices.

Systems and methods for facilitating transactions using a digital currency are described. In some aspects, a system is described for facilitating a private transaction between a first entity and a second entity using a government issued digital currency issued by a government institution. In some aspects, a system is described for facilitating a transaction between a first entity and a second entity using a digital currency issued by a bank or an entity with a bank charter. In some aspects, a digital wallet is described for one or more digital currencies from one or more financial institutions where the digital wallet is a self-hosted digital wallet. In some aspects, a digital wallet is described for one or more digital currencies from one or more financial institutions, including a line of credit based on a digital currency issued by a financial institution and that is fixed with respect to a fiat currency.

In some embodiments, a method for binding a user's information to a user's account with a payment service provider includes receiving a request to pay for a transaction using the user's account with the payment service provider. The request to pay specifies a funding instrument. Additionally, the payment service provider is a source of the funding instrument, and the transaction is between the user and a merchant application. The method also includes generating a common identifier (ID) corresponding to the funding instrument, and generating a payment token corresponding to the common ID and the funding instrument. The common ID is a non-transactable token associated with the merchant application and the user, and the payment token is a non-transactable token that corresponds to the common ID. The method further includes binding the user's payment service provider account to the payment token and the common ID.

A vault system provides a signing manager system and a signing system for transferring assets from a vault that are recorded in a distributed ledger. The signing manager system receives an order to transfer an asset from the vault, validates the order in various ways, and sends a signing request containing the order to the signing system. The signing system is implemented at a secure vault location and securely generates and stores vault private keys. Upon receiving the signing request, the signing system performs various validations, signs the transaction, and sends a signing response to the signing manager system. Upon receiving the signing response, the signing manager system validates the signing response and directs that the signed transaction be recorded in the distributed ledger.

Systems and methods for integrating pay by bank services are disclosed. A method may include a merchant computer program: (1) receiving a request to add funds to a merchant account or wallet; (2) receiving a selection to add an online banking account to the merchant account or wallet; (3) receiving a selection of a funding amount; (4) receiving a selection of a user financial institution; (5) receiving user login credentials for the user financial institution; (6) receiving, from a user financial institution backend, one or more bank accounts associated with the user login credentials; (7) receiving a selection of one of the bank accounts; (8) receiving a token for the selected bank account from a merchant financial institution backend; (9) storing the token in a merchant wallet; and (10) conducting a funding transaction for the funding amount using the token.

Systems and methods to create a customized digital content item and retrieve the digital content item to be displayed are disclosed. Exemplary implementations may effectuate presentation of a customization interface; receive a mint request to mint the digital content item in accordance with a digital content item design; effectuate a transfer of consideration from a user wallet to an administrative wallet; mint the digital content item; transfer a non-fungible token to the user wallet; receive a display request to display the digital content item on a device; determine whether the user wallet holds a non-fungible token associated with the digital content item; responsive to the user wallet holding the non-fungible token, facilitate display of the digital content item on the device; responsive to the user wallet not holding the non-fungible token, take no action to facilitate display of the digital content item on the device; and/or perform other operations.
