Constants

The following sections contain the module constants, also known as parameter types. These can only be changed as part of a runtime upgrade. On the api, these are exposed via api.consts.<module>.<method>.

(NOTE: These were generated from a static/snapshot view of a recent Substrate master node. Some items may not be available in older nodes, or in any customized implementations.)

depositPerContract: BalanceOf#

  • interface: api.consts.contracts.depositPerContract

  • summary: The balance every contract needs to deposit to stay alive indefinitely.

    This is different from the [Self::TombstoneDeposit] because this only needs to be deposited while the contract is alive. Costs for additional storage are added to this base cost.

    This is a simple way to ensure that contracts with empty storage eventually get deleted by making them pay rent. This creates an incentive to remove them early in order to save rent.

depositPerStorageByte: BalanceOf#

  • interface: api.consts.contracts.depositPerStorageByte

  • summary: The balance a contract needs to deposit per storage byte to stay alive indefinitely.

    Let's suppose the deposit is 1,000 BU (balance units)/byte and the rent is 1 BU/byte/day, then a contract with 1,000,000 BU that uses 1,000 bytes of storage would pay no rent. But if the balance reduced to 500,000 BU and the storage stayed the same at 1,000, then it would pay 500 BU/day.

depositPerStorageItem: BalanceOf#

  • interface: api.consts.contracts.depositPerStorageItem

    It works the same as [Self::DepositPerStorageByte] but for storage items.

rentFraction: Perbill#

  • interface: api.consts.contracts.rentFraction

  • summary: The fraction of the deposit that should be used as rent per block.

    When a contract hasn't enough balance deposited to stay alive indefinitely it needs to pay per block for the storage it consumes that is not covered by the deposit. This determines how high this rent payment is per block as a fraction of the deposit.

schedule: Schedule#

  • interface: api.consts.contracts.schedule
  • summary: Cost schedule and limits.

signedClaimHandicap: BlockNumber#

  • interface: api.consts.contracts.signedClaimHandicap

enactmentPeriod: BlockNumber#

  • interface: api.consts.democracy.enactmentPeriod

  • summary: Minimum voting period allowed for a fast-track referendum.
