Single Collateral DAI is a decentralized stablecoin that has collateral to back its value and an interest rate mechanism to stabilize its price. It is designed to be a digital currency with a stable value, that is pegged to the US dollar. (1 SAI=$1) MakerDAO is the decentralized autonomous organization that manages DAI and works to combat its price volatility. MakerDAO hopes to enable more decentralized applications by providing a stable digital currency whose value will not be susceptible to drastic fluctuations. The Maker platform itself, is powered by the MKR token, which is not a stablecoin, and has a volatile price because of its role on the Maker platform. In November of 2019 MakerDAO launched the Multi-Collateral Dai (MCD), which will eventually replace the existing Single-Collateral Dai, and will enable the company to offer a wider range of DeFi services.

The Maker token (MKR) is the MakerDAO native token. It acts as a utility token, governance token and a recapitalization tool for the MakerDAO platform, which manages the DAI stablecoin. MKR is used as part of the stabilizing mechanism that is in place to combat the price volatility of the DAI stablecoin.
DAI is pegged to the US dollar and has collateral in place to ensure stability. The MKR token is used is to pay for the "collateralized debt positions" (CDPs) that have been used to generate DAI. After this MKR is used, it is removed from the supply. MKR holders also contribute to the governance of the MakerDAO and vote on crucial issues related to the direction of the DAI stablecoin.
