Overview

nolint autogenerated code using github.com/rigelrozanski/multitool aliases generated for the following subdirectories: ALIASGEN: github.com/kava-labs/kava/x/pricefeed/types/ ALIASGEN: github.com/kava-labs/kava/x/pricefeed/keeper/

Package pricefeed allows a group of white-listed oracles to post price information of specific markets that are tracked by the system. For each market, the module computes the median of all posted prices by white-listed oracles and takes that as the current price value.
