Aave Risk Stewards propose cap and interest-rate changes across five V3 reserves

What happened

An official Aave governance record proposed Risk Steward changes to borrow and supply caps and interest-rate-model parameters across Aave V3 Core, Base, Mantle, X Layer, and Horizon.

What changed

No parameter is shown as operative yet. If implemented, the proposal would increase the Core wstETH borrow cap from 7,000 to 14,000; lower Base WETH Slope1 from 2.50% to 2.30% and raise optimal utilization from 90% to 92%; raise the Mantle USDe supply cap from 20 million to 40 million; raise X Layer USDC Slope1 from 4.00% to 4.50%; and raise the Horizon USCC supply cap from 5.6 million to 7.5 million.

What did not change

The record does not establish execution, does not change the current Ketju memo, and does not expand the memo's Ethereum GHO/sGHO shelf scope to the affected reserves or networks. It also does not establish a contract failure, loss event, or change to sGHO withdrawal mechanics.

Confirmed

• The official record specifies the proposed current and recommended values for all five reserve changes.
• The Base WETH proposal would reduce the modeled withdrawal buffer at optimal utilization by 1,696 WETH while increasing borrow headroom by the same amount.
• The Mantle USDe and Horizon USCC proposals concern supply caps; the Core wstETH proposal concerns a borrow cap.
• The record says the changes will move forward through the Risk Steward process, but provides no executed transaction in the cached evidence.

Still open

• Whether and when each proposed parameter change will be executed on-chain.
• The final transaction identifiers and effective block numbers for any implemented changes.
• Whether implementation will differ from the values stated in the proposal.

What it means for an advisor

• Monitor the Risk Steward execution record and verify final on-chain values before treating any parameter as changed.
• Do not treat the proposal as approval of the affected reserves or networks; the current Aave v3 memo scope remains limited to Ethereum GHO deposited in sGHO.
• If implemented, record the reduced Base WETH withdrawal buffer at optimal utilization and the expanded cap capacity in the next Aave diligence review.
