Functions

Sends an arbitrary message to receiving chain. Note: Calls authenticated by receiving gateway checking the sender argument.

function sendMessage(address _to, bytes4 _fnSelector, bytes memory _data) external returns (uint64 msgId);

Parameters

Name	Type	Description
`_to`	`address`	The cross-domain contract address which receives the calldata.
`_fnSelector`	`bytes4`	The function selector of the receiving contract.
`_data`	`bytes`	The message calldata, abi.encode(...)

Returns

Name	Type	Description
`msgId`	`uint64`	The index of the message in the inbox, as a message Id, needed to relay the message.

Snapshots can be saved a maximum of once per epoch. Saves snapshot of state root. O(log(count)) where count number of messages in the inbox.

function saveSnapshot() external;

Verifies and relays the message. Note: Gateways expect first argument of message call to be the arbitrum message sender, used for authentication.

function sendMessage(bytes32[] calldata _proof, uint64 _msgId, address _to, bytes calldata _message) external;

Parameters

Name	Type	Description
`_proof`	`bytes32[]`	The merkle proof to prove the message.
`_msgId`	`uint64`	The zero based index of the message in the inbox.
`_to`	`address`	The address to send the message to.
`_message`	`bytes`	The message to relay.

Resolves any challenge of the optimistic claim for 'epoch' using the canonical bridge. Note: Access restricted to canonical bridge.

function resolveDisputedClaim(uint256 _epoch, bytes32 _stateRoot, Claim memory _claim) external;

Parameters

Name	Type	Description
`_epoch`	`uint256`	The epoch to verify.
`_stateRoot`	`bytes32`	The true state root for the epoch.
`_claim`	`Claim`	The claim associated with the epoch.
