Pyth Network is a first-party oracle protocol delivering high-frequency, institution-grade market data directly on-chain for DeFi and other smart contract applications. Emerging from the need to bridge professional trading venues and on-chain markets, it targets the latency, aggregation, and data-quality limitations of legacy oracle designs by sourcing prices from exchanges, market makers, and trading firms themselves. By combining cryptographically signed price updates with a decentralized publishing and aggregation layer, Pyth Network gives protocols access to low-latency, high-fidelity feeds across assets and chains – enabling more capital-efficient trading, risk management, and structured products.
