Skilled persons are aware that digital assets can be valid collateral for a secured loan.
There is known a method for peer to peer secured loan financial technology service with condition matching (KR20170099321). The method comprising the steps of: receiving conditional tailored investment application information including non-cash asset information to be provided as collateral from at least one first information terminal and loan condition information capable of immediate loan; opening a mortgage loan product based on investment application information; receiving loan application information for using the opened mortgage loan product from at least one second information terminal; and a second information terminal, performing a mortgage preliminary procedure by a financial information service apparatus using the second information terminal and the non-cash asset as collateral, and transferring the loan to the account specified in the mortgage application information received from the second information terminal.
There is also known peer to peer loan system (W02017181233) comprising a first electronic device adapted to create a lending bid or borrowing request specifying one or more terms and conditions for a financial loan; a second electronic device, adapted to generate search criteria for a lending bid or a borrowing request including one or more terms and conditions for a financial loan; a server adapted to receive from the first electronic device the lending bid or borrowing request, and receiving from the second electronic device the search criteria, and adapted to be able to match the search criteria to the lending bid or borrowing request if the one or more terms and conditions of the search criteria are similar to those of the lending bid or borrowing request. The server facilitates the exchange of electronic correspondence between the first electronic device and the second electronic device. The system further comprising a database connected to the server and adapted to record the electronic correspondence exchanged between the first electronic device and the second electronic device.
There is also known a system and method for loan managing connected with user's deposit (KR20170097821). The system comprising a loan provision amount processing module adapted for performing a deposit process so that at least a part of cash in a customer's account can be received from the at least one loan offer account desired to be used for the borrower's loan; a database adapted for storing loan provision information of each of the loan offering accounts; a control module for executing a loan in accordance with a predetermined criterion using cash in the operational account in response to a loan request from the borrower; and transferring the loan management profit according to the loan management interest rate set based on the loan interest rate applied to the loan to the loan execution account used for execution of the loan after the execution of the loan.
There is known electronic monetary claim system and method for managing pledging of assigned guarantee of electronic recorded monetary claim with stop condition (W02017038696). According to an embodiment the system is capable of performing communication with a first terminal in an ordering company, a second terminal in a delivering company, a third terminal in a financial institution of the delivering company, and a registry recording device that records recorded registry data, and includes first and second management units. When an order registration for an electronic recorded monetary claim with a stop condition is received from the first terminal and an approval registration with respect to the order registration is received from the second terminal, or when an order reception registration of an electronic recorded monetary claim with a stop condition is received from the second terminal and an approval registration with respect to the order reception registration is received from the first terminal, the first management unit transmits to the registry recording device a request for recording of the generation of the electronic recorded monetary claim with the stop condition. When an assigned guarantee registration is received from the second terminal, the second management unit transmits to the registry recording device an assignment recording request indicating that the electronic recorded monetary claim with the stop condition has been pledged as an assignment guarantee.
