Price Feed: Real-Time Market Data

Price feeds provide real-time cryptocurrency market data to applications and smart contracts that need current asset values. They're like financial news tickers that continuously update with the latest stock prices, but for digital assets and automated systems.

Price feed refers to continuous streams of current market prices and trading data that supply external information to blockchain applications, smart contracts, and DeFi protocols. Accurate price feeds are essential for financial applications that depend on real-time market valuations.

How Price Feeds Work

Data aggregation combines price information from multiple exchanges and trading venues to create more accurate and manipulation-resistant feeds.

Oracle delivery transmits external market data onto blockchain networks where smart contracts can access and use current price information.

Update frequency provides regular price updates at intervals appropriate for different use cases, from seconds for trading to hours for lending protocols.

Real-World Examples

  • Chainlink price feeds providing decentralized oracle networks that supply accurate market data to thousands of DeFi applications
  • Uniswap TWAP oracles using time-weighted average prices from DEX trading to provide manipulation-resistant price references
  • Compound protocol relying on price feeds to determine collateral values and trigger liquidations in lending markets

Why Beginners Should Care

DeFi functionality depends on accurate price feeds for lending, trading, derivatives, and other financial applications to operate correctly.

Security implications from price feed manipulation that can cause protocol exploits, incorrect liquidations, or financial losses.

Oracle importance understanding how external data reaches blockchain applications and the trust assumptions involved.
