In our operational model of peer-to-peer lending, a diverse set of individuals can initiate requests for lending or borrowing. These requests are then organized according to their interest rates, leading to the establishment of an order book. Central to this process is the smart contract, serving as the binding agreement that links the involved parties. This contract safeguards the allocated funds, encompassing the initial loan sum and collateral, as well as the relevant parameters defining the terms. Moreover, it holds the crucial responsibility of overseeing the accurate implementation of the stipulated loan conditions.
