Sky, formerly known as MakerDAO, is one of the first DeFi protocols in the crypto space that introduced the first crypto-backed stablecoin called Dai (DAI), which is set at a value of 1:1 with the United States Dollar. Since the rebranding to Sky, USDS stablecoin was also launched. It is governed by those who hold its governance token MKR or its successor SKY.
