UserOperation represents an EIP-4337 style transaction for a smart contract account.

func (*UserOperation) GetDynamicGasPrice

func (op *UserOperation) GetDynamicGasPrice(basefee *big.Int) *big.Int

GetDynamicGasPrice returns the effective gas price paid by the UserOperation given a basefee. If basefee is nil, it will assume a value of 0.

func (*UserOperation) GetFactory

func (op *UserOperation) GetFactory() common.Address

GetFactory returns the address portion of InitCode if applicable. Otherwise it returns the zero address.

func (*UserOperation) GetMaxGasAvailable

func (op *UserOperation) GetMaxGasAvailable() *big.Int

GetMaxGasAvailable returns the max amount of gas that can be consumed by this UserOperation.

func (*UserOperation) GetMaxPrefund

func (op *UserOperation) GetMaxPrefund() *big.Int

GetMaxPrefund returns the max amount of wei required to pay for gas fees by either the sender or paymaster.

func (*UserOperation) GetPaymaster

func (op *UserOperation) GetPaymaster() common.Address

GetPaymaster returns the address portion of PaymasterAndData if applicable. Otherwise it returns the zero address.

func (*UserOperation) GetUserOpHash

func (op *UserOperation) GetUserOpHash(entryPoint common.Address, chainID *big.Int) string

GetUserOpHash returns the hash of the userOp + entryPoint address + chainID.

func (*UserOperation) MarshalJSON

func (op *UserOperation) MarshalJSON() ([]byte, error)

MarshalJSON returns a JSON encoding of the UserOperation.

func (*UserOperation) Pack

func (op *UserOperation) Pack() []byte

Pack returns a standard message of the userOp. This cannot be used to generate a userOpHash.

func (*UserOperation) PackForSignature

func (op *UserOperation) PackForSignature() []byte

PackForSignature returns a minimal message of the userOp. This can be used to generate a userOpHash.

func (*UserOperation) ToMap

func (op *UserOperation) ToMap() (map[string]any, error)

ToMap returns the current UserOp struct as a map type.

type UserOperationV07

type UserOperationV07 struct {
	Sender             common.Address `json:"sender"               mapstructure:"sender"               validate:"required"`
