-## How Pyth Works on Aptos
-
-Pyth prices are published on Pythnet, and relayed to Aptos using the [Wormhole Network](https://wormholenetwork.com/) as a cross-chain message passing bridge. The Wormhole Network observes when Pyth prices on Pythnet have changed and publishes an off-chain signed message attesting to this fact. This is explained in more detail [here](https://docs.wormholenetwork.com/wormhole/).
-
-This signed message can then be submitted to the Pyth contract on the Aptos networks, which will verify the Wormhole message and update the Pyth contract with the new price.
-
-### On-demand price updates
-
-Price updates are not submitted to the Aptos networks automatically: rather, when a consumer needs to use the value of a price they should first submit the latest Wormhole update for that price to the Pyth contract on the Aptos network they are working on. This will make the most recent price update available on-chain for Aptos contracts to use.

 ## Price Service endpoints
 
 We provide public endpoints for the price service, although it is strongly recommended to host your own instance.

 ## Price Service endpoints
 
 Public endpoints for the Price Service are provided for both mainnet and testnet. These can be used regardless of which network you deploy your own contracts to as long as it is a Pyth supported network. For example, you can use the testnet Price Service whether you are deploying your contract to the BNB or Polygon testnet.
