mStable is a collection of autonomous, decentralised, and non-custodial smart contracts. It is built on Ethereum. mStable was created to address three major problems that confront stablecoin users: significant fragmentation in same-peg stablecoins (there are currently over 5 major USD pegged stablecoins on Ethereum for example) lack of yield in fiat currencies and stablecoins lack of protection against permanent capital loss in stablecoins mStable assets (hereafter mAssets) represent some underlying value peg and are minted/redeemed on-chain via smart contracts.
