Reference

Modifiers

• onlyInitialized

  modifier onlyInitialized()

  ---

  Ensures the `initialize` function was called before.

• onlyValidatorSetContract

  modifier onlyValidatorSetContract()

  ---

  Ensures the caller is the ValidatorSet contract address (EternalStorageProxy proxy contract for ValidatorSet).

Functions

• _getCurrentSeed

  function _getCurrentSeed() internal view returns (uint256)

  ---

  Reads the current random seed from the state.

  Returns:

  uint256

• _initialize

  function _initialize(address _validatorSet) internal

  ---

  Initializes the network parameters. Used by the `initialize` function of a child contract.

  Parameters:

  _validatorSet - The address of the `ValidatorSet` contract.

• _setCurrentSeed

  function _setCurrentSeed(uint256 _seed) internal

  ---

  Updates the current random seed.

  Parameters:

  _seed - A new random seed.

• getCurrentSeed

  function getCurrentSeed() external view returns (uint256)

  ---

  Returns the current random seed accumulated during RANDAO or another process (depending on implementation). This getter can only be called by the `ValidatorSet` contract.

  Modifiers:

  onlyValidatorSetContract

  Returns:

  uint256

• isInitialized

  function isInitialized() public view returns (bool)

  ---

  Returns a boolean flag indicating if the `initialize` function has been called.

  Returns:

  bool

• validatorSetContract

  function validatorSetContract() public view returns (IValidatorSet)

  ---

  Returns the address of the `ValidatorSet` contract.

  Returns:

  IValidatorSet
