MockMessageTransmitter

Title: MockMessageTransmitter

Mock implementation of IMessageTransmitter for testing CCTP

Receives CCTP messages and mints tokens to the recipient

Constants

uint256 constant CCTP_DOMAIN_INDEX = 4

uint256 constant CCTP_NONCE_INDEX = 12

uint256 constant CCTP_TOKEN_INDEX = 120

uint256 constant CCTP_RECIPIENT_INDEX = 152

uint256 constant CCTP_AMOUNT_INDEX = 208

uint256 constant CCTPV2_MESSAGE_BODY_INDEX = 148

uint256 constant CCTPV2_SOURCE_TOKEN_INDEX = CCTPV2_MESSAGE_BODY_INDEX + 4

uint256 constant CCTPV2_MINT_RECIPIENT_INDEX = CCTPV2_MESSAGE_BODY_INDEX + 36

uint256 constant CCTPV2_AMOUNT_INDEX = CCTPV2_MESSAGE_BODY_INDEX + 68

uint256 constant HOOK_DATA_INDEX = CCTPV2_MESSAGE_BODY_INDEX + 228

uint32 public _localDomain

address public tokenMinter

constructor(uint32 localDomain_, address tokenMinter_) ;

Receive and process a CCTP message

function receiveMessage(bytes memory message, bytes calldata attestation) external returns (bool success);

Parameters

Name	Type	Description
`message`	`bytes`	The CCTP message bytes
`attestation`	`bytes`	The attestation signatures (ignored in mock)

Returns

Name	Type	Description
`success`	`bool`	Always returns true for valid messages

Get the local domain

function localDomain() external view returns (uint32);

Set the local domain (testing only)

function setLocalDomain(uint32 newDomain) external;

Set the token minter address (testing only)

function setTokenMinter(address newTokenMinter) external;

Direct mint function for testing

function mintTokens(address token, address recipient, uint256 amount) external;
