beacon.validator.balancestable provides a daily snapshot of ETH balances for active validators on Beacon Chain. This snapshot is taken at the last slot of every day (UTC timing).
Querying balance of a validator by its unique index.
slot_timestamp, validator_index, balance
where validator_index = 10
Output of the sample query above for validator index = 10. As this validator have not updated to a 0x01 withdrawal prefix, excess balance is not withdrawn back to ETH1.
Note: if the validator has specified an ETH1 withdrawal address, reward payments of excess balance over 32 ETH will automatically and regularly be sent to the withdrawal address on ETH1.
