getBridgeTransferData

Returns targets, value, and calldata to execute a bridge transfer.

Intended to be called only by a MakinaXModule instance, from which implementations may read caller state via msg.sender.

function getBridgeTransferData(IBridgeComponent.BridgeOrder calldata order)

        view
        override
        returns (address, address, uint256, bytes memory);

Parameters

Name	Type	Description
order	`IBridgeComponent.BridgeOrder`	The bridge transfer params.

Returns

Name	Type	Description
<none>	`address`	The address of the approval target.
<none>	`address`	The address of the execution target.
<none>	`uint256`	The value to pass along with the calldata.
<none>	`bytes`	The calldata to execute.

setCctpDomain

Associates an EVM chain ID with a CCTP domain in the contract storage.

function setCctpDomain(uint256 evmChainId, uint32 cctpDomain) external override restricted;

Parameters

Name	Type	Description
evmChainId	`uint256`	The EVM chain ID.
cctpDomain	`uint32`	The CCTP domain.
