# Price Feeds Access to reliable, real-world data is essential for decentralised applications (dApps), particularly in Decentralised Finance (DeFi). Real-time asset prices, forming the backbone of any DeFi protocol, are among the most critical data points. This is where Data Feeds come in. Think of them as secure bridges connecting the off-chain world of financial markets to your on-chain smart contracts. They provide a continuous stream of verified, aggregated price data for a wide range of assets, enabling your dApp to react to market fluctuations and operate correctly. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
