Return the latest SUI system state object on-chain.


  • none


SuiSystemStateSummary : <SuiSystemStateSummary>
  • activeValidators : <[SuiValidatorSummary]> - The list of active validators in the current epoch.
  • atRiskValidators : <[SuiAddress]> - Map storing the number of epochs for which each validator has been below the low stake threshold.
  • epoch : <[BigInt_for_uint64]> - The current epoch ID, starting from 0.
  • epochDurationMs : <[BigInt_for_uint64]> - The duration of an epoch, in milliseconds.
  • epochStartTimestampMs : <[BigInt_for_uint64]> - Unix timestamp of the current epoch start
  • inactivePoolsId : <[ObjectID]> - ID of the object that maps from a staking pool ID to the inactive validator that has that pool as its staking pool.
  • inactivePoolsSize : <[BigInt_for_uint64]> - Number of inactive staking pools.
  • maxValidatorCount : <[BigInt_for_uint64]> - Maximum number of active validators at any moment. We do not allow the number of validators in any epoch to go above this.
  • minValidatorJoiningStake : <[BigInt_for_uint64]> - Lower-bound on the amount of stake required to become a validator.
  • pendingActiveValidatorsId : <[ObjectID]> - ID of the object that contains the list of new validators that will join at the end of the epoch.
  • pendingActiveValidatorsSize : <[BigInt_for_uint64]> - Number of new validators that will join at the end of the epoch.
  • pendingRemovals : <[BigInt_for_uint64]> - Removal requests from the validators. Each element is an index pointing to `active_validators`.
  • protocolVersion : <[BigInt_for_uint64]> - The current protocol version, starting from 1.
  • referenceGasPrice : <[BigInt_for_uint64]> - The reference gas price for the current epoch.
  • safeMode : <boolean> - Whether the system is running in a downgraded safe mode due to a non-recoverable bug. This is set whenever we failed to execute advance_epoch, and ended up executing advance_epoch_safe_mode. It can be reset once we are able to successfully execute advance_epoch.
  • safeModeComputationRewards : <[BigInt_for_uint64]> - Amount of computation rewards accumulated (and not yet distributed) during safe mode.
  • safeModeNonRefundableStorageFee : <[BigInt_for_uint64]> - Amount of non-refundable storage fee accumulated during safe mode.
  • safeModeStorageRebates : <[BigInt_for_uint64]> - Amount of storage rebates accumulated (and not yet burned) during safe mode.
  • safeModeStorageRewards : <[BigInt_for_uint64]> - Amount of storage rewards accumulated (and not yet distributed) during safe mode.
  • stakeSubsidyBalance : <[BigInt_for_uint64]> - Balance of SUI set aside for stake subsidies that will be drawn down over time.
  • stakeSubsidyCurrentDistributionAmount : <[BigInt_for_uint64]> - The amount of stake subsidy to be drawn down per epoch. This amount decays and decreases over time.
  • stakeSubsidyDecreaseRate : <uint16> - The rate at which the distribution amount decays at the end of each period. Expressed in basis points.
  • stakeSubsidyDistributionCounter : <[BigInt_for_uint64]> - This counter may be different from the current epoch number if in some epochs we decide to skip the subsidy.
  • stakeSubsidyPeriodLength : <[BigInt_for_uint64]> - Number of distributions to occur before the distribution amount decays.
  • stakeSubsidyStartEpoch : <[BigInt_for_uint64]> - The starting epoch in which stake subsidies start being paid out
  • stakingPoolMappingsId : <[ObjectID]> - ID of the object that maps from staking pool's ID to the sui address of a validator.
  • stakingPoolMappingsSize : <[BigInt_for_uint64]> - Number of staking pool mappings.
  • storageFundNonRefundableBalance : <[BigInt_for_uint64]> - The non-refundable portion of the storage fund coming from storage reinvestment, non-refundable storage rebates and any leftover staking rewards.
  • storageFundTotalObjectStorageRebates : <[BigInt_for_uint64]> - The storage rebates of all the objects on-chain stored in the storage fund.
  • systemStateVersion : <[BigInt_for_uint64]> - The current version of the system state data structure type.
  • totalStake : <[BigInt_for_uint64]> - Total amount of stake from all active validators at the beginning of the epoch.
  • validatorCandidatesId : <[ObjectID]> - ID of the object that stores preactive validators, mapping their addresses to their `Validator` structs.
  • validatorCandidatesSize : <[BigInt_for_uint64]> - Number of preactive validators.
  • validatorLowStakeGracePeriod : <[BigInt_for_uint64]> - A validator can have stake below `validator_low_stake_threshold` for this many epochs before being kicked out.
  • validatorLowStakeThreshold : <[BigInt_for_uint64]> - Validators with stake amount below `validator_low_stake_threshold` are considered to have low stake and will be escorted out of the validator set after being below this threshold for more than `validator_low_stake_grace_period` number of epochs.
  • validatorReportRecords : <[SuiAddress]> - A map storing the records of validator reporting each other.
  • validatorVeryLowStakeThreshold : <[BigInt_for_uint64]> - Validators with stake below `validator_very_low_stake_threshold` will be removed immediately at epoch change, no grace period.
