pyth-crosschain/target_chains/cosmwasm/contracts

Pyth Cosmwasm

This crate includes the actual contract and exposes utilities to interact with the contract on the CosmWasm ecosystem. It also includes an example contract demonstrating how to read price feeds from on-chain CosmWasm applications.

Installation

Add this crate to the dependencies section of your CosmWasm contract's Cargo.toml file:

[dependencies]
pyth-cosmwasm = { git="https://github.com/pyth-network/pyth-crosschain", tag="pyth-cosmwasm-v0.1.0", features=["library"] }

Usage

Simply import the structs exposed by the crate and use them while interacting with the pyth contract. For example:

// to query Pyth contract
use pyth_cosmwasm::msg::{
    PriceFeedResponse,
};

... {
    let price_feed_response: PriceFeedResponse =
    deps.querier.query(&QueryRequest::Wasm(WasmQuery::Smart {
        contract_addr: state.pyth_contract_addr.into_string(),
        msg:           to_binary(&PythQueryMsg::PriceFeed {
            id: state.price_feed_id,
        })?,
    }))?;

    let price_feed = price_feed_response.price_feed;
}
....

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"
    }
}
