Mars Ecosystem is a new decentralized Stablecoin paradigm, which solves the fundamental problem of Stablecoin Protocols (The Positive Externality Problem) 
by internalizing the positive externality: it integrates the creation and the use of stablecoin into one ecosystem. The relationship between Mars Stablecoin and Mars DeFi primitives constitute a positive feedback loop and generates flywheel effect. Mars Stablecoin’ s stability and liquidity is supported by the Mars Ecosystem Token (XMS) and the Mars Treasury. Mars Treasury is funded with multiple types of cryptos. Besides integrations with existing DeFi protocols, Mars Ecosystem builds Mars Swap, Mars Stableswap, Mars Money Market to deliver values to Mars Stablecoin users and XMS holders. XMS holders have governance rights and manages the mars Treasury. And XMS can be staked at DEX to earn part of transaction fees generated at DEX. Mars Swap is a Uniswap-type AMM DEX, which provides deep liquidity between Mars Stablecoin and all the other tokens.
