Following Dharma’s lead, I believe that all stable-coins should have their interest rate model updated to match. DAI and USDT have already been updated to the latest and greatest interest rate model but USDC lags behind.
I have written some new code which allows for the logic used in the existing JumpRateModelV2 to be used for another new contract, LegacyJumpRateModelV2. This contract supports legacy cTokens, like cUSDC.
I propose setting cUSDC interest rate model to a new LegacyJumpRateModelV2 deployed with the same parameters as the current DAI and USDT interest rate models: base rate of 0%, 4% at kink, kink at 80% utilization, and 25% at 100% utilization.
This proposal will finish the standardization of stable coin interest rate models on Compound.
