Staking and Delegation rewards

Current method to check staking rewards​

Rewards payout happens automatically after the end of the epoch and without the need of an explicit transaction being submitted by the service account. Instead of a separate reward payout transaction, the reward payout events will be recorded in the system chunk in the block that is produced at the time of the epoch transition without creating a regular transaction ID.

The rewards payout can be queried by querying the block which contains the system chunk that contains the reward payout events.

where block height is the height of the block containing the rewards payout events

Check staking rewards before May 2023​

Before May 2023, rewards payouts were done manually by the Flow governance committee.

When the transactions executed, they generated events for the rewards paid to each node and delegator. To check the staking and delegation rewards, those transactions should be queried directly.
