How to get staking balance using RPC commands I enabled staking on my wallet. I want to know the staking rewards I got. Is there any rpc command exist to get staking reward balance?

Thanks
A staking system does not exists in Bitcoin's Proof-of-Work consensus model, that being said you will not find any "staking" related functionality in the RPC API. There have been several proposals for a Proof-of-Stake model where this would exist, but of course these have not yet been adopted or have reached any general agreement among the Bitcoin community.
