Bridge
Bridge contract which is deployed on both L1 and L2. Mostly a thin wrapper which calls the library implementations. See IBridge for more details.
The code hash for the same address on L1 and L2 may be different.
MessageStatusChanged
event MessageStatusChanged(bytes32 signal, enum LibBridgeStatus.MessageStatus status)
DestChainEnabled
event DestChainEnabled(uint256 chainId, bool enabled)
receive
receive() external payable
Allow Bridge to receive ETH from EtherVault.
init
function init(address _addressManager) external
Initializer to be called after being deployed behind a proxy.
sendMessage
function sendMessage(struct IBridge.Message message) external payable returns (bytes32 signal)
Sends a message to the destination chain and takes custody of Ether required in this contract. All extra Ether will be refunded.
sendSignal
function sendSignal(bytes32 signal) external
Stores a signal on the bridge contract and emits an event for the relayer to pick up.
processMessage
function processMessage(struct IBridge.Message message, bytes proof) external
retryMessage
function retryMessage(struct IBridge.Message message, bool isLastAttempt) external
isMessageSent
function isMessageSent(bytes32 signal) public view virtual returns (bool)
Checks if a signal has been stored on the bridge contract by the current address.
isMessageReceived
function isMessageReceived(bytes32 signal, uint256 srcChainId, bytes proof) public view virtual returns (bool)
Checks if a signal has been received on the destination chain and sent by the src chain.
isSignalSent
function isSignalSent(address sender, bytes32 signal) public view virtual returns (bool)
Checks if a signal has been stored on the bridge contract by the specified address.
isSignalReceived
function isSignalReceived(bytes32 signal, uint256 srcChainId, address sender, bytes proof) public view virtual returns (bool)
Check if a signal has been received on the destination chain and sent by the specified sender.
getMessageStatus
function getMessageStatus(bytes32 signal) public view virtual returns (enum LibBridgeStatus.MessageStatus)
context
function context() public view returns (struct IBridge.Context)
Returns the bridge state context.
isDestChainEnabled
function isDestChainEnabled(uint256 _chainId) public view returns (bool)
getMessageStatusSlot
function getMessageStatusSlot(bytes32 signal) public pure returns (bytes32)
