# Simple Summary
This ARC proposes updating the mainnet Arc market Loan to Value (LTV) and Liquidation Threshold to be the same asset listed on mainnet V2 market, as determined by Gauntlet.
# Abstract
The risk parameters on the mainnet Arc market are currently not being maintained and are more conservative than those belonging to the same asset on mainnet V2 market. This proposal recommends updating the mainnet Arc market LTV parameter to match the LiquidationThreshold of the same asset listed on mainnet V2 market.
We intend to re-propose a quarterly update of the risk parameters for the mainnet Arc market quarterly in an attempt to keep both markets in sync with mainnet V2 market, or mainnet V3 once live.
# Motivation
This risk parameter change is targeting the following improvements on the Aave Arc Market:
- Align Risk Parameters - The risk parameters on Aave Arc market are currently more conservative and are in need of being updated to better reflect the mainnet V2 market and also the risk profile of the user.
- Improve UX - Increasing LTV ratios and reducing the Liquidity Penalty enables greater capital efficiency across the market.
Given the extra precaution shown when approving Borrowers on the Aave Arc Market, the recommendation is to amend the LTV to reflect the risk profiles of market participants. For now, the intent is to maintain the mainnet Arc market in line with the mainent V2 market on a quarterly basis.

Gauntlet intends to support Arc parameters in Q2 once we have cleared legal considerations and set up a separate instance to simulate Fireblocks markets on the same daily cadence that we do for mainnet V2.
