## Simple Summary
A proposal from Gauntlet to adjust five Interest Rate (IR) Curve parameters in the Ethereum v3 USDC comet and four IR Curve parameters in the Polygon v3 USDC.e comet.
Gauntlet recommends the following IR Curve updates in the Ethereum v3 USDC comet:
* Raise **Annual Borrow Interest Rate Base** from 0.01 to **0.015**
* Raise **Annual Borrow Interest Rate Slope Low** from 0.0333 to **0.0484**
* Raise **Annual Borrow Interest Rate Slope High** from 1.5 to **3.9**
* Raise **Annual Supply Interest Rate Slope Low** from 0.034 to **0.048**
* Raise **Annual Supply Interest Rate Slope High** from 1.5 to **3.4**
Gauntlet recommends the following IR Curve updates in the Polygon v3 USDC.e comet:
* Raise **Annual Borrow Interest Rate Slope Low** from 0.04 to **0.053**
* Raise **Annual Borrow Interest Rate Slope High** from 0.7 to **1.8**
* Raise **Annual Supply Interest Rate Slope Low** from 0.04 to **0.048**
* Raise **Annual Supply Interest Rate Slope High** from 0.65 to **1.6**

## Motivation
Gauntlet recommends adjusting the Ethereum v3 USDC and Polygon v3 USDC.e Interest Rate Curves to ensure that Borrow APR at the kink in all USDC comets is 6% and max Borrow APR in all USDC comets is > 30%.
