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.
