Simulating the MakerDAO Stablecoin

We present a computational simulation framework for the single-collateral stablecoin launched by the MakerDAO project. The simulator, called DAISIM, models investors as portfolio optimizers with heterogeneous risk preferences, and incorporates automated order matching and price update mechanisms to determine the DAI price. DAISIM is being made available as open-source and may be useful in evaluating other similar projects.
