Validating Prices

Upon launching the oracle, you should observe successful price retrieval from the provider sources. Additionally, you have the option to execute the test client script available in the Slinky repository by using the command:

make run-oracle-client

Enable Oracle Vote Extension

In order to utilize the Slinky oracle data in the Initia node, the Oracle setting should be enabled in the config/app.toml file
