XVSBridgeAdmin

XVSBridgeAdmin

The XVSBridgeAdmin contract extends a parent contract AccessControlledV8 for access control, and it manages an external contract called XVSProxyOFT. It maintains a registry of function signatures and names, allowing for dynamic function handling i.e checking of access control of interaction with only owner functions.

upsertSignature

A setter for the registry of functions that are allowed to be executed from proposals.

function upsertSignature(string[] signatures_, bool[] active_) external

Parameters

Name	Type	Description
signatures_	string[]	Function signature to be added or removed.
active_	bool[]	bool value, should be true to add function.

📅 Events

transferBridgeOwnership

This function transfers the ownership of the bridge from this contract to new owner.

function transferBridgeOwnership(address newOwner_) external

Parameters

Name	Type	Description
newOwner_	address	New owner of the XVS Bridge.

isTrustedRemote

Returns true if remote address is trustedRemote corresponds to chainId_.

function isTrustedRemote(uint16 remoteChainId_, bytes remoteAddress_) external returns (bool)

remoteAddress_	bytes	Address of the destination bridge.

Return Values

Name	Type	Description
[0]	bool	Bool indicating whether the remote chain is trusted or not.
