Functions ¶

func AddPercentage ¶

func AddPercentage(value *big.Int, percentage uint16) *big.Int

AddPercentage returns the input value increased by the given percentage.

func ApplyMultiplier ¶

func ApplyMultiplier(feeLimit uint64, multiplier float32) (uint64, error)

func CalculateBumpedFee ¶

func CalculateBumpedFee(
	lggr logger.SugaredLogger,
	currentfeePrice, originalfeePrice, maxFeePriceInput, maxBumpPrice, bumpMin *big.Int,
	bumpPercent uint16,
	toChainUnit feeUnitToChainUnit,
) (*big.Int, error)

CalculateBumpedFee computes the next fee price to attempt as the largest of: - A configured percentage bump (bumpPercent) on top of the baseline price. - A configured fixed amount of Unit (bumpMin) on top of the baseline price. The baseline price is the maximum of the previous fee price attempt and the node's current fee price.

func CalculateFee ¶

func CalculateFee(
	maxFeePrice, defaultPrice, maxFeePriceConfigured *big.Int,
) *big.Int

CalculateFee computes the fee price for a transaction. The fee price is the minimum of: - max fee price specified, default fee price and max fee price for the node.

func IsBumpErr ¶

func IsBumpErr(err error) bool

func MaxBumpedFee ¶

func MaxBumpedFee(originalFeePrice *big.Int, feeBumpPercent uint16, feeBumpUnits *big.Int) *big.Int

MaxBumpedFee returns highest bumped fee price of originalFeePrice bumped by fixed units or percentage.

Types ¶

type Fee ¶

type Fee fmt.Stringer

type Opt ¶

type Opt int

Opt is an option for a gas estimator

const (
	// OptForceRefetch forces the estimator to bust a cache if necessary
	OptForceRefetch Opt = iota
)
