[mUSD](https://medium.com/@mirageprotocol/musd-the-yield-bearing-stablecoin-at-the-center-of-mirage-protocol-e9a407f7b931) - the mirage dollar is minted by providing high quality collateral such as USDC, APT, or MOVE, taking on an over-collateralized debt position.

mUSD serves as margin on the [mirage market](https://docs.mirage.money/mirage-market) perps dex. minters of mUSD act as the counterparty to traders, and as a result earn a significant portion of [protocol fees](https://docs.mirage.money/mirage-market/funding-and-fees#fee-split). these fees go toward paying down the mUSD debt required to unlock deposited collateral. in this respect, mUSD functions as a **self-repaying stablecoin loan.**

**mirage assets can also be used in a variety of leverage and hedging strategies across the Aptos ecosystem.** for more details, see [yield strategies](https://docs.mirage.money/musd/yield-strategies).

in the future, mirage plans to implement yield-bearing strategies on deposited collateral to further accelerate the self-repaying mechanism. see [Alchemix for more details](https://alchemixfi.medium.com/introducing-alchemix-9e7054de54d6) on how this is possible.
