Pyth Cosmwasm

This crate includes the actual contract for the CosmWasm ecosystem.

Integration

You can use pyth-sdk-cw which has been published to crates.io to integrate with the Pyth contract. The sdk exposes data structures and testing utilities for ease of use. Please look into this pyth-sdk-cw

Off-Chain Queries

You can use the provided schemas in the ./pyth/schema directory to directly query the CosmWasm contract from off-chain applications. A typical query requires to pass the price feed id as a hex string. it will look like:

{
    "price_feed": {
        "id": "f9c0172ba10dfa4d19088d94f5bf61d3b54d5bd7483a322a982e1373ee8ea31b"
    }
}

Developing

The cosmwasm contract lives in the pyth subdirectory. From that directory, you can build the contract with cargo build and run unit tests with cargo test.
