Ooki, like many other protocols, uses the BTC/ETH chainlink price feed as the oracle for WBTC. At the time of implementation, this seemed to be a safe approach. However, this solution does not protect the protocol in the event of a Black Swan event such as a WBTC/BTC price depeg. While this event is highly unlikely, it can still be induced.
Therefore, this post suggests that Ooki replaces the oracle for WBTC with a Chainlink-compatible oracle. For this, Ooki should deploy a pull request which calculates the WBTC/ETH price by using the Chainlink price feeds for WBTC/BTC and BTC/ETH.
