Consume Pyth Network prices in applications on Cosmwasm |
Cosmwasm contracts can update and fetch the Pyth prices using the Pyth Cosmwasm Contract, deployed on their network. The documented source code can be found here.
The mechanism by which price feeds are updated on Cosmwasm is explained here. The pyth-common-js can be used to fetch the latest price feed data which then can be passed to the ExecuteMsg on-chain function.
Pyth publishes prices for two kinds of feeds:
- Stable price feeds consist of prices generated on the pythnet blockchain. These feeds are available on both mainnet and testnet blockchains. Use stable feeds if you would like your test environment to be identical to your production environment.
- Edge price feeds consist of prices generated on the pythtest blockchain, which is Pyth's test environment for new features. Consequently, these feeds are not as reliable as the stable feeds, and there are other differences as well (e.g., different price feed ids). These feeds are only available on testnets.
- Minimal on-chain contract which queries the Pyth contract.
Pyth is currently available on the following cosmwasm chains:
