IHomeGateway

Inherits: IArbitrableV2, ISenderGateway

Relays a dispute creation from the ForeignGateway to the home arbitrator using the same parameters as the ones on the foreign chain. Providing incorrect parameters will create a different hash than on the foreignChain and will not affect the actual dispute/arbitrable's ruling. This function accepts the fees payment in the native currency of the home chain, typically ETH.

function relayCreateDispute(RelayCreateDisputeParams memory _params) external payable;

Parameters

Name	Type	Description
`_params`	`RelayCreateDisputeParams`	The parameters of the dispute, see `RelayCreateDisputeParams`.

function relayCreateDispute(RelayCreateDisputeParams memory _params, uint256 _feeAmount) external;

Parameters

Name	Type	Description
`_params`	`RelayCreateDisputeParams`	The parameters of the dispute, see `RelayCreateDisputeParams`.
`_feeAmount`	`uint256`

disputeHashToHomeID

Looks up the local home disputeID for a disputeHash

function disputeHashToHomeID(bytes32 _disputeHash) external view returns (uint256);

Parameters

Returns

Name	Type	Description
`<none>`	`uint256`	disputeID dispute identifier on the home chain

foreignChainID

function foreignChainID() external view returns (uint256);

Returns
