Aave Risk Steward proposes Base WETH interest-rate curve changes

What happened

TokenLogic, acting within the Aave Risk Steward framework, published a proposal to reduce the WETH Slope1 parameter on Aave v3 Base from 2.50% to 2.30% and increase optimal utilization from 90% to 92%.

What changed

A concrete parameter change is now proposed for the Base WETH reserve. If executed, borrowing below the utilization kink would become cheaper and the reserve would operate with a smaller liquidity buffer at optimal utilization.

What did not change

The cached governance record does not establish that the parameters have been executed on-chain. Slope2 is proposed to remain at 8%, and no security incident, asset impairment, or withdrawal halt is reported.

Confirmed

• The proposed Base WETH Slope1 is 2.30%, down from 2.50%.
• The proposed Base WETH Uoptimal is 92%, up from 90%.
• The record states both changes fit within the Risk Steward's single-action limits.
• The proposal leaves Slope2 unchanged at 8%.

Still open

• Whether and when the Risk Stewards will execute the parameter update on-chain.
• How utilization, available withdrawal liquidity, borrower behavior, and reserve revenue will respond if the change is executed.

What it means for an advisor

• Monitor for an execution transaction before treating the new curve as operative.
• Review Base WETH lending and leveraged-staking assumptions if the change executes because borrowing cost and the liquidity buffer at optimal utilization would change.
• Do not infer that the proposed efficiency gain reduces smart-contract, collateral, or liquidity risk.
