L2TimelockTrigger

L2TimelockTrigger(s) acts as an intermediary between multiple V4 smart contracts. The L2TimelockTrigger is responsible for pushing Draws to a DrawBuffer and routing claim requests from a PrizeDistributor to a DrawCalculator. The primary objective is to include a "cooldown" period for all new Draws. Allowing the correction of a malicously set Draw in the unfortunate event an Owner is compromised.

Functions

constructor

  function constructor(
    address _owner,
    contract IDrawBuffer _prizeDistributionBuffer,
    contract IPrizeDistributionBuffer _drawBuffer,
    contract IDrawCalculatorTimelock _timelock
  ) public

Initialize L2TimelockTrigger smart contract.

Parameters:

Name	Type	Description
_owner	address	Address of the L2TimelockTrigger owner.
_prizeDistributionBuffer	contract IDrawBuffer	PrizeDistributionBuffer address
_drawBuffer	contract IPrizeDistributionBuffer	DrawBuffer address
_timelock	contract IDrawCalculatorTimelock	Elapsed seconds before timelocked Draw is available

push

  function push(
    struct IDrawBeacon.Draw _draw,
    struct IPrizeDistributionBuffer.PrizeDistribution _prizeDistribution
  ) external

Push Draw onto draws ring buffer history.

Restricts new draws by forcing a push timelock.

Parameters:

Name	Type	Description
_draw	struct IDrawBeacon.Draw	Draw struct from IDrawBeacon
_prizeDistribution	struct IPrizeDistributionBuffer.PrizeDistribution	PrizeDistribution struct from IPrizeDistributionBuffer

manager

  function manager(
  ) public returns (address)

Gets current _manager.

Return Values:

Type	Description
address	Current _manager address.

setManager

  function setManager(
    address _newManager
  ) external returns (bool)

Set or change of manager.

Throws if called by any account other than the owner.

Parameters:

Name	Type	Description

pendingOwner

  function pendingOwner(

Gets current _pendingOwner.

Return Values:

Type	Description
address	Current _pendingOwner address.

renounceOwnership

  function renounceOwnership(
  ) external

Renounce ownership of the contract.

Leaves the contract without owner. It will not be possible to call onlyOwner functions anymore. Can only be called by the current owner. NOTE: Renouncing ownership will leave the contract without an owner, thereby removing any functionality that is only available to the owner.

transferOwnership

  function transferOwnership(
    address _newOwner
  ) external

Allows current owner to set the _pendingOwner address.

Parameters:

Name	Type	Description
_newOwner	address	Address to transfer ownership to.

claimOwnership

  function claimOwnership(
  ) external

Allows the _pendingOwner address to finalize the transfer.

This function is only callable by the _pendingOwner.

Events

Parameters:

Name	Type	Description
drawId	uint32	Draw ID
prizeDistribution	struct IDrawBeacon.Draw	PrizeDistribution

ManagerTransferred

  event ManagerTransferred(
    address previousManager,
    address newManager
  )
