Chainlink Data Feeds
Build with Data Feeds
Asset prices, proof of reserves, NAV, and interest rates, aggregated from many sources by decentralized oracle networks and published onchain on dozens of networks. Lending markets, stablecoins, and tokenized funds use them to value collateral and settle positions, and your contract can read the latest value in a single call.
Get Started
Getting Started
Deploy a Solidity consumer contract and read your first price feed.
Using Data Feeds on EVM Chains
Read feeds onchain and offchain with Solidity, Vyper, JavaScript, Python, or Go.
Get Historical Data
Retrieve past round answers for charts, analytics, and time-weighted averages.
Read MVR Feeds
Read multi-variable feed bundles with Solidity, ethers.js, or viem.
Data Feeds on Solana
Read feeds onchain from a Solana program or offchain from a client application.
Data Feeds on Aptos
Write and publish a Move module that reads Data Feeds on Aptos testnet.
Feed Types
