IGasFeePricing

Methods

estimateGasFee

function estimateGasFee(uint256 _dstChainId, bytes _options) external nonpayable returns (uint256)

Returns srcGasToken fee to charge in wei for the cross-chain message based on the gas limit

Parameters

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
_0	uint256	undefined

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	Gas ratio of dstGasToken / srcGasToken
