Admin Functions

The following functions are available to projects that hold ownership rights over an Asset Controller.

Access Control

The Asset Controller contract uses OpenZeppelin’s AccessControl module. To grant, revoke, or check roles for an address, use the standard functions available in the AccessControl contract.

The following roles are available:

Role	keccak256 hash	Description
DEFAULT_ADMIN_ROLE	0x0000000000000000000000000000000000000000000000000000000000000000	Full access to all admin functions
PAUSE_ROLE	0x139c2898040ef16910dc9f44dc697df79363da767d8bc92f2e310312b816e46d	Can pause the message sending, resending and execution functions

Admin functions

The following functions can only be called by an account with the DEFAULT_ADMIN_ROLE role.

setLimits

Sets the local bridge adapters on the same chain that can be used to relay messages to the Controller contract and assigns a 24h mint&burn limit.

function setLimits(address _bridge, uint256 _mintingLimit, uint256 _burningLimit) external;

Name	Type	Description
bridge	address	The address of the bridge to set the limits for
mintingLimit	uint256	The minting limit in wei per 24h.
burningLimit	uint256	The burning limit in wei per 24h.

---

setMinBridges

Sets the minimum number of bridges required to relay an asset when performing multi-bridge transfers without mint/burn limits. Setting this value to 0 will disable multi-bridge transfers entirely.

function setMinBridges(uint256 _minBridges) public;

Name	Type	Description
_minBridges	uint256	The minimum number of bridges required.

---

setMultiBridgeAdapters

Adds a bridge adapter to the whitelist of adapters that can be used for multi-bridge transfers without applying mint/burn limits.

function setMultiBridgeAdapters(address[] memory adapter, bool[] memory enabled) public;

Input Params:

Name	Type	Description
adapter	address[]	An array of adapter addresses of the bridge adapters.
enabled	bool[]	An array of the status of the adapters. True to enable, false to disable. Adapterand enabled must have the same length.

---

setControllerForChain

Sets the foreign controller contract addresses for the specified chain IDs. To disable a controller on a given chain, its address should be set to the zero address (address(0)).

function setControllerForChain(uint256[] memory chainId, address[] memory controller) public

Input params:

Name	Type	Description
chainId	uint256[]	An array of chain id to set controllers for
controller	address[]	An array of controller addresses to set for the corresponding chainIds. Both arrays must have the same length.

---

pauseTransfersToChain

Pauses or unpauses the initiation of new transfers to a specific chain.

function pauseTransfersToChain(uint256 _chainId, bool _pause) public

Input params:

Name	Type	Description
chainId	uint256	The chain ID to pause or unpause transfers to.
pause	bool	True to pause transfers, false to unpause.

Pause functions

The following functions can only be called by accounts with the PAUSE_ROLE:

pause

Pauses the contract. This disables the following functions: transferTo(), resendTransfer()and execute() .

 function pause() public;

---

unpause

Unpauses the contract, re-enabling the functions listed above.

 function unpause() public;
