High Dependence on Chainlink Can Be Mitigated
Summary
By now the protocol release and has a high dependence in chainlink feeds, due this if a feed is down this will affect directly to the protocol.
Vulnerability Details
Not implementing a mitigation measure for Chainlink errors, such as using a TWAP from Uniswap for the ETH/USD feed to determine the ETH price in USD, increases the risk of protocol disruptions should there be issues with the Chainlink feed.
Impact
The difference between a mitigation measure and the absence of one makes a significant impact on maintaining the most important pair feeds operational. Given its critical importance to the protocol, I consider this a risk.
Tools Used
Manual review
Recommendations
Use the ETH/USD orderbook uses Uniswap's TWAP as a backup feed to get ETH price in USD. Even though the price precession may be not as good as chainlink feeds this will help the protocol to stay up. At least in that strategy/lending vault.
