Pyth Core Upgrade
Pyth Core is upgrading on July 31, 2026. Prepare your integration.
Pyth Network is upgrading Pyth Core on July 31, 2026. This upgrade replaces Pyth Core's underlying data infrastructure with an improved version while preserving the existing Hermes API surface and on-chain contract interface.
What you get
- Higher-frequency updates for faster price moves.
- Additional price feeds beyond the current Core catalog.
- Lower latency across the data path.
Most existing integrations keep working through the cutover. Prepare for the upgrade to check whether you're covered. The one new requirement is authentication on Hermes: every Hermes user needs a Pyth API Key by July 31, 2026.
