Rune Christensen, CEO of the Maker Foundation, revealed Multi-Collateral Dai (MCD) is ready to launch on Nov. 18. MCD is a planned upgrade to the Maker protocol that enables the support of multiple collateral types. Christensen added the upgrade would also include new features, such as Dai Savings Rate (DSR), "which will allow users to earn on their Dai ($DAI) holdings." The MCD system can only be activated by Maker ($MKR) holders through an executive voting process starting Nov. 15.
