Overview

The Governance precompile provides comprehensive access to the Cosmos SDK’s x/gov module, enabling smart contracts to participate in on-chain governance. It allows for submitting and canceling proposals, depositing funds, and casting votes. Additionally, it offers extensive query capabilities to retrieve information about proposals, votes, deposits, and overall governance parameters.
