Popular “price oracles” (as they are often called) in DeFi include Chainlink Price Feeds, Compound Protocol’s [Open Price Feed](https://compound.finance/docs/prices), Uniswap’s [Time-Weighted Average Prices (TWAPs)](https://docs.uniswap.org/contracts/v2/concepts/core-concepts/oracles), and [Maker Oracles](https://docs.makerdao.com/smart-contract-modules/oracle-module).

Builders should understand the caveats that come with these price oracles before integrating them into their project. This [article](https://blog.openzeppelin.com/secure-smart-contract-guidelines-the-dangers-of-price-oracles/) provides a detailed analysis of what to consider when planning to use any of the price oracles mentioned.
