Pyth Network plays a critical role in decentralized finance (DeFi) by supplying real-time, accurate market data for smart contracts. This data supports a wide range of applications, including decentralized exchanges (DEXs), lending protocols, derivatives platforms, and stablecoins that rely on external price feeds for their functionality. Beyond DeFi, Pyth can be used in insurance, prediction markets, and any blockchain-based application that requires secure, reliable real-world data. The PYTH token also serves as a governance tool, allowing holders to influence network upgrades and policies.
