Name	Type	Description
_dstChainId	uint256	undefined
_options	bytes	Versioned struct used to instruct relayer on how to proceed with gas limits. Contains data on gas limit to submit tx with.

Returns

Name	Type	Description

owner

function owner() external view returns (address)

Returns the address of the current owner.

Returns

Name	Type	Description
_0	address	undefined

renounceOwnership

function renounceOwnership() external nonpayable

Leaves the contract without owner. It will not be possible to call onlyOwner functions anymore. Can only be called by the current owner. NOTE: Renouncing ownership will leave the contract without an owner, thereby removing any functionality that is only available to the owner.

setCostPerChain

function setCostPerChain(uint256 _dstChainId, uint256 _gasUnitPrice, uint256 _gasTokenPriceRatio) external nonpayable

Permissioned method to allow an off-chain party to set what each dstChain's gas cost is priced in the srcChain's native gas currency. Example: call on ETH, setCostPerChain(43114, 30000000000, 25180000000000000) chain ID 43114 Average of 30 gwei cost to transaction on 43114 AVAX/ETH = 0.02518, scaled to gas in wei = 25180000000000000

Parameters

Name	Type	Description
_dstChainId	uint256	The destination chain ID - typically, standard EVM chain ID, but differs on nonEVM chains
_gasUnitPrice	uint256	The estimated current gas price in wei of the destination chain
_gasTokenPriceRatio	uint256	USD gas ratio of dstGasToken / srcGasToken

transferOwnership

function transferOwnership(address newOwner) external nonpayable

Transfers ownership of the contract to a new account (newOwner). Can only be called by the current owner.

Parameters

Name	Type	Description
newOwner	address	undefined

Events

OwnershipTransferred

event OwnershipTransferred(address indexed previousOwner, address indexed newOwner)

Parameters
