A computing system, the computing system comprising: the service of the deposit token-making is that, the deposit tokenization service is used for: Receiving a request from a first client to transfer a token deposit to a second client, wherein the token deposit corresponds to a banking asset or a banking liability, and wherein the token deposit is recorded on a first blockchain, and Identifying a second blockchain for the second client, wherein the first blockchain is different from the second blockchain, and An interoperability service is provided for the user to perform, the interoperability service is used for: The token deposit is transferred from the first blockchain to the second blockchain.
9. 9. The computing system of claim 8, wherein the interoperability service is to destroy the token deposit from the first blockchain and cast the token deposit to the second blockchain to transfer the token deposit from the first blockchain to the second blockchain.
10. 10. The computing system of claim 8, wherein the first client and the second client are commercial banks, and wherein the interoperability service is to transfer accounting tokens of an issuing bank from a first blockchain to the second blockchain.
11. 11. The computing system of claim 8, wherein the first blockchain and the second blockchain are a common blockchain.
12. 12. The computing system of claim 8, wherein the first blockchain and the second blockchain are private licensed blockchains, and wherein the computing system hosts at least one node of the first blockchain and at least one node of the second blockchain.
13. 13. The computing system of claim 8, wherein the interoperability service comprises at least one of a universal payment channel and a universal payment bridge for transferring the token deposit from the first blockchain to the second blockchain.
14. 14. The computing system of claim 8, wherein the deposit tokenization service is further to verify legal monetary reserves of the token deposit.
15. 15. The computing system of claim 8, further comprising an Application Programming Interface (API) for communicating with the first client.
16. 16. The computing system of claim 8, further comprising a smart contract library, wherein the smart contract library includes smart contract features selectable by the first client for generating smart contracts.
17. 17. The computing system of claim 16, wherein the deposit tokenization service is further to generate a escrow contract based on the library of intelligent contracts, wherein the escrow contract is to record a stable coin corresponding to the token deposit on a third blockchain.
18. 18. The computing system of claim 17, wherein the third blockchain is different from the first blockchain and the second blockchain, and wherein the third blockchain is a federated licensed blockchain.
19. 19. The computing system of claim 17, wherein the third blockchain is different from the first and second blockchains, and wherein the third blockchain is a common blockchain.
20. 20. A method for performing a token deposit transaction, the method comprising: a node hosting a first blockchain by a first commercial banking system; Sending, by the first commercial banking system, a first request to a payment network system via an Application Programming Interface (API), wherein the first request is for casting a token deposit to the first blockchain, wherein the token deposit corresponds to a banking asset or a banking liability; Updating, by the first commercial banking system, the first blockchain based on the payment network system casting the token deposit; Transmitting, by the first commercial banking system, a second request to a payment network system via the API, wherein the second request is for transferring the token deposit to a second commercial banking system associated with a second blockchain, wherein the payment network system transfers the token deposit by destroying the token deposit from the first blockchain and casting the token deposit to the second blockchain, and Updating, by the first commercial banking system, the first blockchain based on the payment network system destroying the token deposit.

Description

Deposit medallion system RELATED APPLICATIONS The present application claims priority from greek patent application No. 20230100784, entitled "DEPOSIT TOKENIZATION SYSTEM", filed 29 at 9 at 2023, and from U.S. provisional application No. 63/549,640, entitled "BANK TOKENS ANDTHEIR INTERBANK TRANSFERS", filed 5 at 2 at 2024, the disclosures of which are incorporated herein by reference in their entirety. Technical Field The following disclosure relates generally to Deposit Tokenization (DT) systems that can provide a platform for commercial banks and their customers to cast, destroy and/or transfer token deposits within a particular commercial bank or between different commercial banks. Background The development of digital currency has prompted the need to tokenize legal currency that circulates over blockchain. Types of digital currencies that have emerged include cryptocurrency, stationary currency, central Banking Digital Currency (CBDC), and scribbling bank deposits. Despite the need to scrip legal currencies, there are many problems with how to implement such scrip. For example, if a bank or country pursues different versions of a scripted deposit product, problems associated with legal monetary scrip may occur. Thus, there is a need for devices, systems, and methods that enable interoperability between banks associated with scrip in legal currency. Disclosure of Invention According to one aspect, the present disclosure provides a method for performing a token deposit transaction. The method may include receiving a request from a first client to perform a token deposit transaction for a banking asset or a banking liability. The method may also include identifying a second client in the token deposit transaction and determining an address associated with the second client. The method may further include verifying legal monetary reserves of the bank asset or bank liability and casting a deposit of tokens of the bank asset or bank liability to the first blockchain. The method may further include initiating a reserve contract to hold central bank digital currency to provide a guarantee for the token deposit transaction. The method may also include transferring the token deposit to an address associated with the second client. According to another aspect, the present disclosure provides a computing system. The computing system may include a deposit tokenization service and an interoperability service. The deposit tokenization service may receive a request from a first client to transfer a token deposit to a second client. The token deposit may correspond to a banking asset or a banking liability. The token deposit may be recorded on the first blockchain. The deposit tokenization service may also identify a second blockchain for the second client. The first blockchain may be different from the second blockchain. The interoperability service may transfer the token deposit from the first blockchain to the second blockchain. According to yet another aspect, the present disclosure provides a method for performing a token deposit transaction. The method may include hosting, by a first commercial banking system, a node of a first blockchain, and sending, by the first commercial banking system, a first request to a payment network system via an Application Programming Interface (API). The first request may be for casting a token deposit to a first blockchain. The token deposit may correspond to a banking asset or a banking liability. The method may also include updating, by the first commercial banking system, the first blockchain based on the payment network system casting the token deposit. The method may further include sending, by the first commercial banking system, a second request to the payment network system via the API. The second request may be for transferring the token deposit to a second commercial banking system associated with a second blockchain. The payment network system may transfer the token deposit by destroying the token deposit from the first blockchain and casting the token deposit to the second blockchain. The method may also include updating, by the first commercial banking system, the first blockchain based on destroying the token deposit by the payment network system.
