Chainlink Price Feeds give smart contract developers a simple way to fetch current and historical asset prices. Asset prices are updated by decentralized oracle networks which aggregate results from high-quality data providers.

Chainlink is constantly upgrading how price feed data is updated and aggregated on-chain. Users should point to the new addresses in order to automatically support the latest releases for price feeds. For more information about how to upgrade, see Migrating to Aggregator Proxies.
