Maker is a utility token, governance token and recapitalization resource of the Dai Credit System. MKR is required for paying fees on a CDP (Collateralized Debt Position) that has been used to generate DAI. As the demand for DAI and CDP's fluctuate, the total supply of MKR will fluctuate as well in order to stabilize the price of DAI. MKR is also used as a governance token for modifying the risk management and business logic of the Maker system. Holders of MKR can vote on specific risk parameters for each collateral asset and CDP type.
