Hey, I’m building on EVM and looking for a way to get Pyth prices pushed on-chain automatically (heartbeat + deviation-based updates) instead of pulling updates in every transaction.
I found the Pulse Scheduler contracts in the pyth-crosschain repo (target_chains/ethereum/contracts/contracts/pulse/) - subscriptions with prepaid balances, keepers push updates, consumers read via a whitelist. That’s exactly what I need.
But I can’t find it in the docs or any deployed addresses. Is Pulse live anywhere I can integrate with? If so, which chains, and is there a guide or contract address? If it’s not launched yet, any rough timeline - or should I just run price-pusher for now?
Hey!
Pyth Pulse isn’t a supported product. The contracts currently visible in the repository were never officially shipped, so there are no supported deployments, integration docs, or contract addresses to use, and we don’t recommend building on them. There isn’t a launch timeline to share.
For heartbeat- or deviation-based on-chain updates, use a supported scheduler/Price Pusher setup.
For a new EVM integration, please use Pyth Pro as the data source and the upgraded Pyth Core contracts for on-chain integration. Avoid starting with the legacy Core flow (as it will be deprecated on Aug 18th, 2026). The upgraded Core preserves the familiar contract interface while using the newer Pro-backed architecture.
