const GasProofVerification uint32 = 200_000

GasProofVerification is an upper limit on the gas used for verifying the VRF proof on-chain. It can be used to estimate the amount of LINK needed to fulfill a request.

Functions

func EstimateFeeJuels 

func EstimateFeeJuels(callbackGasLimit uint32, maxGasPriceWei, weiPerUnitLink *big.Int) (*big.Int, error)

EstimateFeeJuels estimates the amount of link needed to fulfill a request given the callback gas limit, the gas price, and the wei per unit link. An error is returned if the wei per unit link provided is zero.

func EstimateFeeWei 

func EstimateFeeWei(callbackGasLimit uint32, maxGasPriceWei *big.Int) (*big.Int, error)

EstimateFeeWei estimates the amount of wei needed to fulfill a request

func MaybeSubtractReservedEth 

func MaybeSubtractReservedEth(q pg.Q, startBalance *big.Int, chainID uint64, subID *big.Int, vrfVersion vrfcommon.Version) (*big.Int, error)

MaybeSubtractReservedEth figures out how much ether is reserved for other VRF requests that have not been fully confirmed yet on-chain, and subtracts that from the given startBalance, and returns that value if there are no errors. 

func MaybeSubtractReservedLink(q pg.Q, startBalance *big.Int, chainID uint64, subID *big.Int, vrfVersion vrfcommon.Version) (*big.Int, error)

MaybeSubtractReservedLink figures out how much LINK is reserved for other VRF requests that have not been fully confirmed yet on-chain, and subtracts that from the given startBalance, and returns that value if there are no errors.
