The Compound Open Price Feed is a system to allow various sources to sign off-chain data about prices and allow any Ethereum account to move that data on-chain.1

It has a price storage contract that stores prices signed by any address, and another contract that only stores prices within an acceptable bound of the Uniswap time-weighted average price and are signed by a reporter2.

Currently, [Coinbase Pro](https://pro.coinbase.com/) is the reporter.
