Answer: Multi-collateral Dai (MCD) is a new version of the Dai stablecoin that allows users to collateralize their assets in order to generate Dai. This new version of Dai allows users to use a variety of assets, such as ETH, BAT, and USDC, as collateral. MCD also allows for upgrades and improvements to be made to the Dai protocol without requiring a hard fork. This means that users can benefit from the latest features and improvements without having to switch to a different version of Dai.
