An ERC-4337 UserOperation (v0.6 format).

Fields

sender: [u8; 20]

Smart account address.

nonce: Uint256

Anti-replay nonce (key + sequence) as uint256.

init_code: Vec<u8>

Factory + factoryData for account creation (empty if account exists).

call_data: Vec<u8>

Encoded function call on the smart account.

call_gas_limit: Uint256

Gas limit for the execution phase (uint256).

verification_gas_limit: Uint256

Gas for validation (validateUserOp + validatePaymasterUserOp) (uint256).

pre_verification_gas: Uint256

Gas paid for the bundle tx overhead (uint256).

max_fee_per_gas: Uint256

Maximum fee per gas (EIP-1559) (uint256).

max_priority_fee_per_gas: Uint256

Maximum priority fee per gas (uint256).

paymaster_and_data: Vec<u8>

Paymaster address + data (empty if self-paying).

signature: Vec<u8>

Signature over the UserOp hash.

Implementations

impl UserOperation

pub fn new(sender: [u8; 20]) -> Self

Create a new UserOperation with default gas values.

pub fn hash(&self, entry_point: &[u8; 20], chain_id: Uint256) -> [u8; 32]

Compute the userOpHash for signing.

keccak256(abi.encode(pack(userOp), entryPoint, chainId))

This is the hash that the account validates in validateUserOp.

pub fn encode(&self) -> Vec<u8>

ABI-encode the full UserOperation for bundler submission.

Encodes as a tuple matching the Solidity struct layout.

Trait Implementations

impl Clone for UserOperation

fn clone(&self) -> UserOperation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UserOperation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for UserOperation

fn eq(&self, other: &UserOperation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
