constructor()

The contract constructor, that deploys the Multisig plugin logic contract.

Functions

implementation

function implementation() external view returns (address)

Selector: 0x5c60da1b

Returns the plugin implementation address.

Dev: The implementation can be instantiated via the new keyword, cloned via the minimal proxy pattern (see ERC-1167), or proxied via the UUPS proxy pattern (see ERC-1822).

Returns	Type	Description
[0]	address	The address of the plugin implementation contract.

prepareInstallation

function prepareInstallation(
    address _dao,
    bytes _data
) external returns (address plugin, IPluginSetup.PreparedSetupData preparedSetupData)

Selector: 0xf10832f1

Prepares the installation of a plugin.

Parameter	Type	Description
_dao	address	The address of the installing DAO.
_data	bytes	The bytes-encoded data containing the input parameters for the installation as specified in the plugin's build metadata JSON file.

Returns	Type	Description
plugin	address	The address of the Plugin contract being prepared for installation.
preparedSetupData	IPluginSetup.PreparedSetupData	The deployed plugin's relevant data which consists of helpers and permissions.

prepareUninstallation

function prepareUninstallation(
    address _dao,
    IPluginSetup.SetupPayload _payload
) external view returns (PermissionLib.MultiTargetPermission[] permissions)

Selector: 0x9cb0a124

Prepares the uninstallation of a plugin.

Parameter	Type	Description
_dao	address	The address of the uninstalling DAO.
_payload	IPluginSetup.SetupPayload	The relevant data necessary for the prepareUninstallation. See above.

Returns	Type	Description
permissions	PermissionLib.MultiTargetPermission[]	The array of multi-targeted permission operations to be applied by the PluginSetupProcessor to the uninstalling DAO.

prepareUpdate

function prepareUpdate(
    address _dao,
    uint16 _fromBuild,
    IPluginSetup.SetupPayload _payload
) external returns (bytes initData, IPluginSetup.PreparedSetupData preparedSetupData)

Selector: 0xa8a9c29e

Prepares the update of a plugin.

Dev: Revoke the upgrade plugin permission to the DAO for all builds prior the current one (3).

Parameter	Type	Description
_dao	address	The address of the updating DAO.
_fromBuild	uint16	The build number of the plugin to update from.
_payload	IPluginSetup.SetupPayload	The relevant data necessary for the prepareUpdate. See above.

Returns	Type	Description
initData	bytes	The initialization data to be passed to upgradeable contracts when the update is applied in the PluginSetupProcessor.
preparedSetupData	IPluginSetup.PreparedSetupData	The deployed plugin's relevant data which consists of helpers and permissions.

protocolVersion

function protocolVersion() external pure returns (uint8[3])

Selector: 0x2ae9c600

Returns the semantic Aragon OSx protocol version number that the implementing contract is associated with.

Dev: This version number is not to be confused with the release and build numbers found in the Version.Tag struct inside the PluginRepo contract being used to version plugin setup and associated plugin implementation contracts.

Returns	Type	Description
[0]	uint8[3]	Returns the semantic Aragon OSx protocol version number.

supportsInterface

function supportsInterface(bytes4 _interfaceId) external view returns (bool)

Selector: 0x01ffc9a7

Checks if this or the parent contract supports an interface by its ID.

Parameter	Type	Description
_interfaceId	bytes4	The ID of the interface.

Errors

InvalidUpdatePath

error InvalidUpdatePath(uint16 fromBuild, uint16 thisBuild)

Thrown when an update path is not available, for example, if this is the initial build.

Parameter	Type	Description
fromBuild	uint16	The build number to update from.
thisBuild	uint16	The build number of this setup to update to.

Structs

PreparedSetupData

Inherited from IPluginSetup.

struct PreparedSetupData {
    address[] helpers;
    PermissionLib.MultiTargetPermission[] permissions;
}

The data associated with a prepared setup.

Field	Type	Description
helpers	address[]	The address array of helpers (contracts or EOAs) associated with this plugin version after the installation or update.
permissions	PermissionLib.MultiTargetPermission[]	The array of multi-targeted permission operations to be applied by the PluginSetupProcessor to the installing or updating DAO.

SetupPayload

Inherited from IPluginSetup.

struct SetupPayload {
    address plugin;
    address[] currentHelpers;
    bytes data;
}

The payload for plugin updates and uninstallations containing the existing contracts as well as optional data to be consumed by the plugin setup.

Field	Type	Description
plugin	address	The address of the Plugin.
currentHelpers	address[]	The address array of all current helpers (contracts or EOAs) associated with the plugin to update from.
data	bytes	The bytes-encoded data containing the input parameters for the preparation of update/uninstall as specified in the corresponding ABI on the version's metadata.
