We support freezing USDC, USDT, DAI, FRAX, and MAI on Aave V3 Avalanche and set the LTV to 0. This will minimize additional risks in case of further de-pegging, not only USDC.
We believed that as of now, we should not fully pause all the supply/borrow markets. We should do a risk assessment across all V2 and V3 deployments.
