Batch add validator keys for
id. pubkeys and signatures are the concatenated public keys and signatures without padding. Id node operator’s owner only.Truncate all unused validator keys previously submitted for
id. Id node operator’s owner only.Update the
operator.rewardAddress to newRewardAddress for id. By default, the reward address is the same as operator.operatorOwner. Id node operator’s owner only.Update the
operator.depositLimit to newDepositLimit for id, which is the new maximal number of active validators the operator could get assigned. We recommend it to be the current total number of validator keys, but it could go beyond the current validator key total number. Id node operator’s owner only.Last modified 6mo ago
