Pyth – Real-Time Price Oracle, Market Data Layer & Low-Latency Feeds

#Quasa #QUA #Pyth

Pyth is a price oracle and market-data layer. Publishers—exchanges, trading firms, and data vendors—push signed prices off-chain. Apps pull the latest signed update and submit it on-chain in one transaction. That pull model updates roughly every 400 ms and avoids the gas cost of pushing every feed. There are more than 3,000 live feeds across crypto, equities, FX, and commodities, with confidence intervals. Pyth Pro adds low-latency WebSocket streams (1–50 ms) for institutions and trading systems. Indices and a data marketplace sit alongside. Named users include Hyperliquid, Polymarket, Kalshi, Coinbase, and Tradeweb. The site cites more than 100 chains, more than 700 consumers, and trillions in transaction volume as of September 2026. Hermes now requires an API key; on-chain contracts stay permissionless.

• Nasdaq Basic and other traditional feeds on the marketplace
• SOC-style institutional path on Pro  

𝗣𝗢𝗧𝗘𝗡𝗧𝗜𝗔𝗟 𝗖𝗢𝗡𝗦𝗜𝗗𝗘𝗥𝗔𝗧𝗜𝗢𝗡𝗦
• Hermes API key is now required for off-chain reads
• A signed price is only as good as the publishers behind it
• On-chain update still costs gas
• Pro is a commercial subscription
• Oracle risk remains if a major publisher fails
