Events

Add / Remove Bridge

event AddBridge(string chain, address bridgeContract);
event RemoveBridge(string chain, address bridgeContract);

Event occurs when Bridge Contract is registered or removed from Orbit Hub Contract

• string chain : Chain symbol corresponding to Bridge Contract ( ex, ETH, KLAYTN, TERRA )

• address bridgeContract : Bridge Contract Address

Add / Remove BridgeGovernance

event AddBridgeGovernance(string chain, bytes wallet, bytes32 govId);
event RemoveBridgeGovernance(bytes32 govId);

Event occurs when governance is registered or removed to manage Orbit Bridge System by Orbit Hub Governance

• string chain : Chain symbol of Vault managed by Governance

• bytes wallet : Address of Vault managed by Governance

• bytes32 govId : Unique Identifier of Governance

Add / Remove BridgeInfo

event AddBridgeInfo(string chain, bytes32 govId);
event RemoveBridgeInfo(string chain, bytes32 govId);

Event occurs when Bridge Governance adds or removes information such as Multi-Sig Wallet and nonce to be used in Bridge Contract

• string chain : Chain symbol corresponding to Bridge Contract ( ex, ETH, KLAYTN, TERRA )

• bytes32 govId : Unique Identifier of Governance

ChangeGovernanceMig

event ChangeGovernanceMig(bytes32 govId, bytes32 chainId, address mig);

Event occurs when Bridge Governance replaces OrbitHub or Brdige Multi-Sig Wallet

• bytes32 govId : Unique Identifier of Governance

• bytes32 chainId : Unique Identifier of Chain Symbol

• address mig : Multi-Sig Wallet Contract Address

SwapRelay

event SwapRelay(string fromChain, bytes32[] bytes32s, uint[] uints);

Event occurs when Bridge Operator relays bridging data

• string fromChain : Chain Symbol requesting bridging

• bytes32[] bytes32s : Bytes32 data array used in the bridging consensus process

• uint[] uints : Uint data array used in the bridging consensus process

SwapValidated

event SwapValidated(uint dataIndex, string fromChain, bytes32[] bytes32s, uint[] uints, address[] vaList);

Event occurs when Bridge Validator completes consensus on bridging data
