Timelock

Venus has two active Timelock source families with the same transaction tuple but different administration semantics. BNB mainnet’s three Governor Bravo routes use the legacy Solidity 0.5 Timelock. Destination-mainnet governance artifacts use Solidity 0.8.25 TimelockV8.

TimelockV8 allows setPendingAdmin from the current admin as well as from the timelock itself, rejects duplicate queue/cancel state transitions, validates nonzero admins, and exposes GRACE_PERIOD, MINIMUM_DELAY, and MAXIMUM_DELAY as virtual view functions. The legacy contract permits setPendingAdmin only through the timelock itself. Select the contract family by network and bytecode before relying on those differences.

Solidity API

setDelay

Setter for the transaction queue delay

function setDelay(uint256 delay_) public

Parameters

Name	Type	Description
delay_	uint256	The new delay period for the transaction queue

acceptAdmin

Method for accepting a proposed admin

function acceptAdmin() public

setPendingAdmin

Method to propose a new admin authorized to call timelock functions. This should be the Governor Contract

function setPendingAdmin(address pendingAdmin_) public

Parameters

Name	Type	Description
pendingAdmin_	address	Address of the proposed admin

queueTransaction

Called for each action when queuing a proposal

function queueTransaction(address target, uint256 value, string signature, bytes data, uint256 eta) public returns (bytes32)

Parameters

Name	Type	Description
target	address	Address of the contract with the method to be called
value	uint256	Native token amount sent with the transaction
signature	string	Signature of the function to be called
data	bytes	Arguments to be passed to the function when called
eta	uint256	Timestamp after which the transaction can be executed

Return Values

Name	Type	Description
[0]	bytes32	Hash of the queued transaction

cancelTransaction

Called to cancel a queued transaction

function cancelTransaction(address target, uint256 value, string signature, bytes data, uint256 eta) public

Parameters

Name	Type	Description
target	address	Address of the contract with the method to be called
value	uint256	Native token amount sent with the transaction
signature	string	Signature of the function to be called
data	bytes	Arguments to be passed to the function when called
eta	uint256	Timestamp after which the transaction can be executed

executeTransaction

Called to execute a queued transaction

function executeTransaction(address target, uint256 value, string signature, bytes data, uint256 eta) public payable returns (bytes)

Parameters

Name	Type	Description
target	address	Address of the contract with the method to be called
value	uint256	Native token amount sent with the transaction
signature	string	Signature of the function to be called
data	bytes	Arguments to be passed to the function when called
eta	uint256	Timestamp after which the transaction can be executed
