Timelock ​

0xb5f2000b5744f207c931526cAE2134cAa8b6862a | ABI JSON

The Timelock contract introduces a mandatory delay between proposal scheduling and execution in the governance system. It ensures that all governance actions are publicly visible for a minimum time before they can take effect.

Inherits: AccessControl, IERC721Receiver, IERC1155Receiver

State Variables ​

minDelay ​

The minimum delay required between scheduling and executing an operation.

solidity
uint256 public minDelay;

View Functions ​

isOperation ​

Returns whether an operation has been scheduled.

solidity
function isOperation(bytes32 id) public view virtual returns (bool registered);

isOperationPending ​

Returns whether an operation is pending (scheduled but not yet executed or cancelled).

solidity
function isOperationPending(bytes32 id) public view virtual returns (bool pending);

isOperationReady ​

Returns whether an operation is ready for execution (delay has passed).

solidity
function isOperationReady(bytes32 id) public view virtual returns (bool ready);

isOperationDone ​

Returns whether an operation has been executed.

solidity
function isOperationDone(bytes32 id) public view virtual returns (bool done);

getMinDelay ​

Returns the minimum delay required for operations.

solidity
function getMinDelay() external view returns (uint256 duration);

hashOperation ​

Computes the operation hash for a single operation. Useful for tracking operation status.

solidity
function hashOperation(
    address target,
    uint256 value,
    bytes calldata data,
    bytes32 predecessor,
    bytes32 salt
) public pure virtual returns (bytes32 hash);

hashOperationBatch ​

Computes the operation hash for a batch operation. Useful for tracking operation status.

solidity
function hashOperationBatch(
    address[] calldata targets,
    uint256[] calldata values,
    bytes[] calldata payloads,
    bytes32 predecessor,
    bytes32 salt
) public pure virtual returns (bytes32 hash);

Events ​

CallScheduled ​

Emitted when an operation is scheduled.

solidity
event CallScheduled(
    bytes32 indexed id,
    uint256 indexed index,
    address target,
    uint256 value,
    bytes data,
    bytes32 predecessor,
    uint256 delay
);

CallExecuted ​

Emitted when an operation is executed.

solidity
event CallExecuted(
    bytes32 indexed id,
    uint256 indexed index,
    address target,
    uint256 value,
    bytes data
);

Cancelled ​

Emitted when an operation is cancelled.

solidity
event Cancelled(bytes32 indexed id);

MinDelayChange ​

Emitted when the minimum delay is changed.

solidity
event MinDelayChange(uint256 oldDuration, uint256 newDuration);
