mStable is a decentralized stablecoin ecosystem that allows users to trade and earn yield on stablecoins. Powered by the MTA token, the protocol offers a Meta Harvester vault for yield farming and opportunities to earn over 100% APR through MTA liquidity on Optimism Velodrome. Additionally, users can participate in MTA Buyback, where they can burn MTA to receive stablecoin yield. mStable has been acquired by dHEDGE, positioning it as a leading yield vault aggregator in the DeFi ecosystem.
