AccessManagerOmnichainFacet

Facet to manage access of Omnichain Data Managers to DataObjects

approveOmnichainDataManager

function approveOmnichainDataManager(DataPoint dp, address dm, bool approved) external payable

Approves a DataManager for a DataPoint allocated on another chain

Caller SHOULD send native coin with this call to pay omnichain fees Refund will be sent to the caller, so if it's a contract it should have receive() function

Parameters

Name	Type	Description
dp	DataPoint	DataPoint
dm	address	DataManager
approved	bool	approve (true) or remove approval (false)

approveOmnichainDataManager

function approveOmnichainDataManager(DataPoint dp, OmnichainAddress dm, bool approved) external payable

Approves a DataManager for a DataPoint allocated on another chain

Function SHOULD be restricted to DataPoint maintainer only Caller SHOULD send native coin with this call to pay omnichain fees Refund will be sent to the caller, so if it's a contract it should have receive() function NOTE: Here we support: - Local DataPoint & local DataManager (send zero msg.value) - Local DataPoint & remote DataManager - Remote DataPoint & local DataManager

Parameters

Name	Type	Description
dp	DataPoint	DataPoint
dm	OmnichainAddress	DataManager, can be on another chain
approved	bool	approve (true) or remove approval (false)

approveOmnichainDataManagers

function approveOmnichainDataManagers(DataPoint dp, OmnichainAddress[] dms, bool approved, address payable refundAddress) external payable

Approves a list of DataManagers in different chains

Caller SHOULD send native coin with this call to pay omnichain fees Amount can be calculated with estimateApproveOmnichainDataManagers() NOTE: We only support local DataPoints here, DataManager can be both remote and local

Parameters

Name	Type	Description
dp	DataPoint	DataPoint (Should be allocated on current chain!)
dms	OmnichainAddress[]	List of DataManagers to approve
approved	bool	approve (true) or remove approval (false), this value will be applied to all DataManagers
refundAddress	address payable	who will receive refund, if any

estimateApproveOmnichainDataManagers

function estimateApproveOmnichainDataManagers(DataPoint dp, OmnichainAddress[] dms, bool approved) external view returns (uint256)

Calculates native coin fee required to call approveOmnichainDataManagers()

Parameters

Name	Type	Description
dp	DataPoint	DataPoint (Should be allocated on current chain!)
dms	OmnichainAddress[]	List of DataManagers to approve
approved	bool	approve (true) or remove approval (false), this value will be applied to all DataManagers

Return Values

Name	Type	Description
[0]	uint256	native coin fee, which should be sent as `msg.value`

approvedDataManager

function approvedDataManager(DataPoint dp, OmnichainAddress dm) external view returns (bool)

Verifies if DataManager is allowed to write in specific DataPoint

Parameters

Name	Type	Description
dp	DataPoint	Identifier of the DataPoint
dm	OmnichainAddress	DataManager, can be on another chain

Return Values

Name	Type	Description
[0]	bool	if write access is allowed

approveDataManager

function approveDataManager(DataPoint dp, OmnichainAddress dm, bool approved) external

Defines if DataManager is allowed to write in specific DataPoint

Function SHOULD be restricted to DataPoint maintainer only

Parameters

Name	Type	Description
dp	DataPoint	Identifier of the DataPoint
dm	OmnichainAddress	DataManager, can be on another chain
approved	bool	if DataManager should be approved for the DataPoint

approvedOmnichainDataObject

function approvedOmnichainDataObject(OmnichainAddress remoteDataObject) external view returns (bool)

Verifies if remote DataObject is approved to access local one (with same address) via writeOmnichain() call

Parameters

Name	Type	Description
remoteDataObject	OmnichainAddress	Address and chainId of remote DataObject

approveOmnichainDataObject

function approveOmnichainDataObject(uint32[] chains, bool approved) external

Approves DataObjects with same address as caller's local address to write to the caller for all DataPoints

Parameters

Name	Type	Description
chains	uint32[]	List of chains to approve
approved	bool	if provided chains should be approved (true) or removed from approved list (false)
