Simple Summary
Upgrade sOIL to track new price sources such as OTC desk trading.
Abstract
Aim is to diversify the amount of data sources we use for the oil feed in order to not rely on a limited number of data sources and help decentralize the reliability of the pair as a result.
Motivation
The current pair doesn’t rely on enough data sources we aim to improve this by working with Chainlink adding OTC trade data and deploying a new aggregator.
