IOracleMiddlewareWithDataStreams

Git Source

Inherits: ICommonOracleMiddleware, IChainlinkDataStreamsOracle

The oracle middleware is a contract that is used by the USDN protocol to validate price data. Using a middleware allows the protocol to later upgrade to a new oracle logic without having to modify the protocol's contracts.

This middleware uses Chainlink Data Streams and Pyth as the low-latency oracle, and Chainlink Data Feeds as fallback. For liquidations, either Pyth or Data Streams can be used. For validations, only Data Streams is accepted.
