IMultisig

Description

An interface for an on-chain multisig governance plugin in which a proposal passes if X out of Y approvals are met.

Implementation

external function addAddresses

Adds new members to the address list. Previously, it checks if the new address list length would be greater than type(uint16).max, the maximal number of approvals.

function addAddresses(address[] _members) external

Input	Type	Description
_members	address[]	The addresses of the members to be added.

external function removeAddresses

Removes existing members from the address list. Previously, it checks if the new address list length is at least as long as the minimum approvals parameter requires. Note that minApprovals is must be at least 1 so the address list cannot become empty.

function removeAddresses(address[] _members) external

Input	Type	Description
_members	address[]	The addresses of the members to be removed.

external function approve

Approves and, optionally, executes the proposal.

function approve(uint256 _proposalId, bool _tryExecution) external

Input	Type	Description
_proposalId	uint256	The ID of the proposal.
_tryExecution	bool	If true, execution is tried after the approval cast. The call does not revert if execution is not possible.

external function canApprove

Checks if an account can participate on a proposal vote. This can be because the vote

• was executed, or
• the voter is not listed.

function canApprove(uint256 _proposalId, address _account) external view returns (bool)

Input	Type	Description
_proposalId	uint256	The proposal Id.
_account	address	The address of the user to check.
Output
0	bool	Returns true if the account is allowed to vote.

The function assumes the queried proposal exists.

external function canExecute

Checks if a proposal can be executed.

function canExecute(uint256 _proposalId) external view returns (bool)

Input	Type	Description
_proposalId	uint256	The ID of the proposal to be checked.
Output
0	bool	True if the proposal can be executed, false otherwise.

external function hasApproved

Returns whether the account has approved the proposal. Note, that this does not check if the account is listed.

function hasApproved(uint256 _proposalId, address _account) external view returns (bool)

Input	Type	Description
_proposalId	uint256	The ID of the proposal.
_account	address	The account address to be checked.
Output
0	bool	The vote option cast by a voter for a certain proposal.

external function execute

Executes a proposal.

function execute(uint256 _proposalId) external

Input	Type	Description
_proposalId	uint256	The ID of the proposal to be executed.
