price-feeder

The price-feeder tool is responsible for performing the following:

1. Fetching and aggregating exchange rate price data from various providers, e.g. Binance and Coinbase, based on operator configuration. These exchange rates are exposed via an API and are used to feed into the main oracle process.
2. Taking aggregated exchange rate price data and submitting those exchange rates on-chain to persistence-sdk x/oracle.

Steps to run price-feeder locally:

1. make install (builds and installs price-feeder binary)

   • Set environment variable for the password ORACLE_FEEDER_KEY_PASSPHRASE=test.
   • Set the config variable keyring.passphrase
4. run: price-feeder price-feeder.example.toml to start the price-feeder
