+author: "ACI"
+discussions: "https://governance.aave.com/t/arfc-adjusting-interest-rate-curve-for-weeth-on-arbitrum/17804"
+snapshot: "https://snapshot.org/#/aave.eth/proposal/0xed2fd3dfee1f29f04b6cda4a5c4629fcca32a5c961b1b3e2a49ba6842367ce31"
+---
+
+## Simple Summary
+
+The current proposal suggests adjusting the Interest Rate Curve for weETH on Arbitrum network to align with the mainnet, so Risk Parameters will be the same for weETH on Mainnet, Arbitrum, and Base networks.
+
+The aim is to optimize the utilization rates and improve revenue for the DAO.
+
+## Motivation
+
+By adjusting the Interest Rate Curve and updating the RF, we aim to encourage Increase efficiency and optimize DAO revenue for the weETH asset.
+
+## Specification
+
+Change Arbitrum Risk Parameters for weETH to align with Mainnet & Base.
+
+**Proposed Changes:**
+
+| Parameter      | Value  |
+| -------------- | ------ |
+| Uoptimal       | 35.00% |
+| Reserve Factor | 45.00% |
