## What happened

LlamaRisk proposed raising caps for the Maple Spoke on Arc and the Ethena Ecosystem Spoke on Ethereum, and changing the stablecoin rate curves on the Ethereum Plus Hub.

## What changed

The proposal doubles the Arc Maple USDC draw cap to 46 million and the syrupUSDC add cap to 50 million. On the Ethereum Plus Hub it sets a 40 million USDe add cap, 12 million add and draw caps for USDC and USDT, and higher rate parameters.

## What did not change

Ketju has not found that the changes executed, and they give no reason to review Aave V4 again. The Aave V3 configuration does not change.

## Confirmed

- The recommendation raises the Arc Maple USDC draw cap from 23 million to 46 million and the syrupUSDC add cap from 25 million to 50 million.
- The recommendation raises the Ethereum Plus Hub USDC and USDT slope1 from 4.50% to 4.60% and the USDe base rate from 6.30% to 6.60%.
- The author states that the changes will go through the Risk Steward process.

## Still open

- Ketju has not verified the implementation transactions or the live parameters after the change.
- Ketju must reproduce the live liquidity of the matching asset, which the memo uses as the denominator, before it can test the memo's limit on Spoke draw caps.

## What it means for an advisor

- Ketju will add the proposed limits for each Spoke to its Aave V4 file and check them against the liquidity limit the memo names.
- Ketju does not approve Aave V4 and will review it again only after governance executes the change and Ketju reproduces it from the live contracts.
