Pyth is live
on Conflux eSpace
With the recent launch of Pythnet - a dedicated app-chain for Pyth price aggregation - and the integration with the Wormhole Protocol, your dApp can now permissionlessly request and consume any of the 200+ Pyth price feeds directly on Conflux eSpace.
What is Pyth?
The Pyth network is a first-party financial oracle network designed to publish continuous real-world data on-chain in a tamper-resistant, decentralized, and self-sustainable environment.
The network is designed to incentivize market participants — exchanges, market makers, and financial services providers — to share directly on-chain the price data collected as part of their existing operations. The network then aggregates this first-party price data and makes it available for free to either on- or off-chain applications.
In less than a year, the network secured more than $2.0B in total value, supported up to $3.8B in monthly trading volume ($30B+ in total), and exceeded 500K client downloads.
Pyth currently supports 200+ price feeds including crypto, equities (including the full US 30), FX, metals, and more — and updates twice per second without any access restriction. Upcoming feeds include Conflux eSpace ecosystem tokens.

How does Pyth Work
on Conflux eSpace ?
Pyth prices are published and aggregated on Pythnet and then relayed to Conflux eSpace using the Wormhole Network as a cross-chain message passing protocol. Wormhole observes when Pyth prices on Pythnet have changed and publishes an off-chain signed message attesting to this fact.
This signed price update message can then be submitted to the Pyth contract. The contract verifies the Wormhole message and updates the on-chain Pyth price to the new price.
Pyth does not automatically submit the prices to the networks; Protocols and users are responsible for updating the on-chain Pyth price before using it.
Is your dApp also on a L2? Fear not as it works the same.
Please visit the docs to check the corresponding contract and learn more.
