Functions

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

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