MakerDAO will officially release Multi-Collateral Dai on November 18th. A milestone in the stablecoin field. With this upgrade, Dai will support more collateral types and the long-awaited Dai Savings Rate (DSR). The collateral types promises to increase the stability of Dai while making various DeFi applications simpler and more economical.
Following Maker’s suggestion, Tokenlon will be referring to the existing Dai(Single-Collateral Dai) as SAI on Nov. 18 23:00 (UTC + 8), and will be supporting and referring the new MCD-generated Dai as DAI in the following two days.
Despite both SAI and DAI will be supported, users need to migrate their SAI to DAI before SAI gets phased out, which is expected in a few months. We recommend users to use Maker’s migration portal for this conversion: http://migrate.makerdao.com/
