# Pyth2Wormhole
|
|
|
|
This repository acts as a monorepo for the various components that make up
|
|
Pyth2Wormhole. The base repository is a fork from Certus One's reference
|
|
[Wormhole][] implementation in order to take advantage of the existing tooling
|
|
for building projects based on Wormhole's various SDKs. Much of the existing
|
|
documentation from there will also apply to this repository.
|
|
|
|
[Wormhole]: https://github.com/certusone/wormhole
|
|
|
|
Within this monorepo you will find the following subprojects:
|
|
|
|
## Pyth2Wormhole Solana
|
|
> solana/pyth2wormhole
|
|
|
|
|
|
The main Pyth implementation currently exists as an [on-chain contract][] on
|
|
Solana. In order to expose these prices cross-chain, the Pyth2Wormhole Solana
|
|
contract acts as a sender for Pyth prices. At regular intervals the Pyth
|
|
contract will observe the current Pyth price for selected products, and produce
|
|
an attestation which is then relayed over Wormhole to be consumed by the
|
|
various P2W receiver contracts.

|
|
|
|
## Pyth2Wormhole Ethereum
|
|
> ethereum/contracts/pyth
|
|
|
|
The Ethereum P2W contract acts as a receiver for Pyth prices relayed from the
|
|
P2W Solana contract. It also provides a public API for other Ethereum contracts
|
|
that can be used to consume Pyth prices. For a guide on using this API to
|
|
consume Pyth price feeds see [pyth-evm-sdk][] which contains documented
|
|
examples.

|
|
|
|
## Pyth2Wormhole Price Service
|
|
> third_party/pyth
|
|
|
|
The P2W Price Service is an off-chain service which constantly observes the
|
|
Wormhole network watching for price attestations emitted from the Pyth Solana
|
|
contract. It exposes all observed attestations via a public API over HTTPS/WSS
|
|
which can be consumed by client-side applications that wish to use Pyth pricing
|
|
data.
|
|
|
|
For a guide on utilising this service in your project, see the documentation in
|
|
the [pyth-js][] repository.
