This application is for people who own some NFT token, they need money but don't want to sell their's token, they can list the token in our application as collateral, and other users can give them a loan. So, the borrower got the money, their token is locked in our smart contract. When the time of repayment comes in, the borrower has to pay the original money plus interest to the lender, if they are not, then the token will be transferred to the lender.
