Liquity is an Ethereum based lending protocol that offers zero interest loans. That sounds like a pretty good deal, doesn’t it? They still charge a small fee when you close the loan but zero interest is zero interest, right? They can afford to do this since LQTY has no user interface and nobody is in charge. It is simply a piece of code on the Ethereum blockchain. You give the code some Ethereum, and the code gives you a stablecoin called LUSD. Since you gave them ETH, the stablecoin is essentially backed by your own money. You can stake LUSD to earn LQTY rewards. You can also earn LQTY by maintaining a front end for the network.
