On a Lend-Leverage farm interaction structure, lending and borrowing, interest payment, and asset return proceed safely with automated smart contracts. In addition, Meshswap manages a separate Safety Fund related to lending on its own in order to safely manage the assets and profits of a lender. The safety fund is a rainy day fund accumulated from leverage farmers who have exceeded a certain level of safety standard. And in the event of contingencies in which a lending pool asset utilized by leverage farmers cannot be returned, the Safety Fund will be used to cover the shortage instead. As a result, a lender can safely enjoy opportunities to generate profits by minimizing the asset loss risk.
