BumpDynamicFeeOnly bumps the tip cap and max gas price if necessary.

BumpLegacyGasPriceOnly will increase the price and apply multiplier to the gas limit.

HexToInt64 performs the inverse of Int64ToHex Returns 0 on invalid input.

Int64ToHex converts an int64 into go-ethereum's hex representation.

NewBlockHistoryEstimator returns a new BlockHistoryEstimator that listens for new heads and updates the base gas price dynamically based on the configured percentile of gas prices in that block.

NewEstimator returns the estimator for a given config.

NewFixedPriceEstimator returns a new "FixedPrice" estimator which will always use the config default values for gas prices and limits.

NewL2SuggestedPriceEstimator returns a new Estimator which uses the L2 suggested gas price.

ArbGasInfo_getPricesInArbGas is the a hex encoded call to: `function getPricesInArbGas() external view returns (uint256, uint256, uint256);`.

ArbGasInfoAddress is the address of the "Precompiled contract that exists in every Arbitrum chain." https://github.com/OffchainLabs/nitro/blob/f7645453cfc77bf3e3644ea1ac031eff629df325/contracts/src/precompiles/ArbGasInfo.sol.

OptForceRefetch forces the estimator to bust a cache if necessary.

MaxStartTime is the maximum amount of time we are allowed to spend trying to fill initial data on start.
