Types

type Overhead

type Overhead struct {
	// contains filtered or unexported fields
}

Overhead provides helper methods for calculating gas limits based on pre-defined parameters.

func NewDefaultOverhead

func NewDefaultOverhead() *Overhead

NewDefaultOverhead returns an instance of Overhead using parameters defined by the Ethereum protocol.

func (*Overhead) CalcPreVerificationGas

func (ov *Overhead) CalcPreVerificationGas(op *userop.UserOperation) *big.Int

CalcPreVerificationGas returns an expected gas cost for processing a UserOperation from a batch.

func (*Overhead) NonZeroValueCall

func (ov *Overhead) NonZeroValueCall() *big.Int

NonZeroValueCall returns an expected gas cost of using the CALL opcode in the context of EIP-4337. See https://github.com/wolflo/evm-opcodes/blob/main/gas.md#aa-1-call.
