-The main Pyth implementation currently exists as an [on-chain contract][] on
-Pythnet, a separate instance of the Solana blockchain. In order to expose
-these prices cross-chain, the Wormhole Attester 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 receiver contracts.

 # Pyth Price Service
 
+** Pyth price service is deprecated. Please use [Hermes](../../hermes/) instead. **
+
 The Pyth price service is a webservice that listens to the Wormhole Network for Pyth price updates and serves them via a
 convenient web API. The service allows users to easily query for recent price updates via a REST API, or subscribe to
 a websocket for streaming updates. [Price service JS client](https://github.com/pyth-network/pyth-crosschain/tree/main/price_service/sdk/js) connects
 to an instance of the price service in order to fetch on-demand price updates.
 
-## Public Endpoints
-
-The Pyth Data Association operates two public endpoints for the price service, for mainnet and testnet respectively.
-These endpoints can be used to test integrations with Pyth Network:
-
-| network | url                             |
-| ------- | ------------------------------- |
-| mainnet | https://xc-mainnet.pyth.network |
-| testnet | https://xc-testnet.pyth.network |
-
-For production deployments, developers integrating with Pyth Network are **strongly encouraged** to host their own instance of the price service for maximum resilience and decentralization.
-By running an independent instance of this service, developers tap directly into Wormhole's peer-to-peer network to stream Pyth price updates.
-This peer-to-peer network has built-in redundancy and is therefore inherently more reliable than a centralized service operated by the PDA.
-
 ## Wormhole Spy
 
 The price service depends on a Wormhole Spy to stream Pyth messages from the Wormhole Network to it. The
