RelayBridgeFactory

Factory contract for deploying RelayBridge instances for different assets This factory deploys new RelayBridge contracts and maintains a registry of bridges by asset address

HYPERLANE_MAILBOX

address HYPERLANE_MAILBOX

The Hyperlane mailbox address used for cross-chain messaging Immutable to ensure consistency across all deployed bridges

bridgesByAsset

mapping(address => address[]) bridgesByAsset

Mapping from asset address to array of deployed bridge addresses Multiple bridges can exist for the same asset

BridgeDeployed

event BridgeDeployed(address bridge, address asset, contract BridgeProxy proxyBridge)

Emitted when a new bridge is deployed

Parameters

Name	Type	Description
bridge	address	The address of the newly deployed RelayBridge contract
asset	address	The address of the asset that the bridge will handle
proxyBridge	contract BridgeProxy	The BridgeProxy contract associated with this bridge

constructor

constructor(address hMailbox) public

Initializes the factory with the Hyperlane mailbox address The mailbox address cannot be changed after deployment

Parameters

Name	Type	Description
hMailbox	address	The address of the Hyperlane mailbox contract

deployBridge

function deployBridge(address asset, contract BridgeProxy proxyBridge) public returns (address)

Deploys a new RelayBridge for a specific asset Creates a new RelayBridge instance and adds it to the bridgesByAsset mapping

Parameters

Name	Type	Description
asset	address	The address of the asset (token) that the bridge will handle
proxyBridge	contract BridgeProxy	The BridgeProxy contract that will work with this bridge
