Summary
Gauntlet recommends updating the borrow interest rate model for the Ethereum WETH Comet.
This proposal implements the following parameter changes:
| Parameter | Current | Proposed |
|---|
| Annual Borrow Interest Rate Base | 1.00% | 1.50% |
| Annual Borrow Interest Rate Slope Low | 1.111111% | 0.5556% |
No supply-side interest rate parameters are changed. The borrow kink and borrow slope above the kink also remain unchanged.
The proposed adjustment pivots the borrow curve below the 90% utilization kink. It is intended to reduce reserve depletion at lower utilization levels while keeping borrowing costs effectively unchanged at and above the kink.
Proposal Actions
- Set the annual borrow interest rate base to
0.015.
- Set the annual borrow interest rate slope below the kink to
0.005556.
- Deploy and upgrade the Ethereum WETH Comet to apply the updated configuration.
