## Simple Summary
A proposal from Gauntlet to adjust six Interest Rate (IR) Curve parameters in each of the Arbitrum v3 USDC Native, Arbitrum v3 USDC.e, & Base v3 USDbC comets.
Gauntlet recommends the following IR Curve updates in each comet:
* Raise **Annual Borrow Interest Rate Slope Low** from 0.035 to **0.053**
* Raise **Borrow Kink** from 0.8 to **0.85**
* Raise **Annual Borrow Interest Rate Slope High** from 0.25 to **1.8**
* Raise **Annual Supply Interest Rate Slope Low** from 0.0325 to **0.048**
* Raise **Supply Kink** from 0.8 to **0.85**
* Raise **Annual Supply Interest Rate Slope High** from 0.4 to **1.6**

## Motivation
Gauntlet recommends adjusting the Arbitrum v3 USDC Native, Arbitrum v3 USDC.e, and Base v3 USDbC Interest Rate (IR) Curves with four main objectives:
1. Raise Borrow APR and Supply APR rates at the kink due to sustained high utilization
2. Increase the kinks
3. Ensure positive reserve growth beyond the kink
4. Increase the rate caps

## Specification
The proposal updates the IR curve parameters by using the respective methods in the `Configurator`.
