The price feeder is a tool that validators use to submit oracle prices to Exocore nodes.
This tool fetches token prices from off-chain sources such as CEX and DEX, then submits this price information to the Exocore blockchain network as a standard Cosmos SDK transaction. Once the submitted prices from validators reach the voting power threshold, they achieve consensus on-chain and become the final price.
