​
Overview

The Staking precompile provides a comprehensive interface to the Cosmos SDK’s x/staking module, enabling smart contracts to engage in staking activities. This includes creating and managing validators, delegating and undelegating tokens, and querying a wide range of staking-related information, such as validator details, delegation records, and staking pool status. Precompile Address: 0x0000000000000000000000000000000000000800 Related Module: x/staking

      delegatorAddress,
      validatorAddress,
