Introduction to Data Feeds
Connect Your Smart Contracts to the Outside World
Chainlink Data Feeds are the quickest way to connect your smart contracts to the real-world market prices of assets. For example, one use for data feeds is to enable smart contracts to retrieve the latest pricing data 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 Data Feeds to determine prices on their derivatives platform. Lending and Borrowing platforms like AAVE use Data Feeds to ensure the total value of the collateral.
The Decentralized Data Model describes how Data Feeds are aggregated from many data sources and published on-chain.
