Introduction to Price Feeds

Connect Your Smart Contracts to the Outside World

Chainlink Price Feeds are the quickest way to connect your smart contracts to the real-world market prices of assets. They enable smart contracts to retrieve the latest price of an asset in a single call.

Retrieve the Latest Asset Prices

Often, smart contracts need to act upon prices of assets in real-time. This is especially true in DeFi.

For example, Synthetix use Price Feeds to determine prices on their derivatives platform. Lending and Borrowing platforms like AAVE use Price Feeds to ensure the total value of the collateral.

The Decentralized Data Model describes how Price Feeds are aggregated from many data sources and published on-chain.
