A ZKsync-native transaction type with additional fields. Besides additional fields, represents an EIP-1559 transaction.

Note: Unlike EIP-1559, does not have access_list field.

Fields

chain_id: ChainId

EIP-155: Simple replay attack protection

nonce: U256

A scalar value equal to the number of transactions sent by the sender; formally Tn.

gas: u64

A scalar value equal to the maximum amount of gas that should be used in executing this transaction. This is paid up-front, before any computation is done and may not be increased later; formally Tg.

max_fee_per_gas: u128

A scalar value equal to the maximum amount of gas that should be used in executing this transaction. This is paid up-front, before any computation is done and may not be increased later; formally Tg.

As ethereum circulation is around 120mil eth as of 2022 that is around 120000000000000000000000000 wei we are safe to use u128 as its max number is: 340282366920938463463374607431768211455

This is also known as GasFeeCap

max_priority_fee_per_gas: u128

Max Priority fee that transaction is paying

As ethereum circulation is around 120mil eth as of 2022 that is around 120000000000000000000000000 wei we are safe to use u128 as its max number is: 340282366920938463463374607431768211455

This is also known as GasTipCap

to: Address

Address of the receiver of the message. Unlike with other transactions, this field must be present. In case of the contract deployment, the address should be set to the deployer system contract, and the payload should contain ABI-encoded salt, contract bytecode hash, and constructor arguments.

from: Address

Address of the sender of the message.

value: U256

A scalar value equal to the number of Wei to be transferred to the message call’s recipient or, in the case of contract creation, as an endowment to the newly created account; formally Tv.

input: Bytes

Input has two uses depending if transaction is Create or Call (if to field is None or Some). pub init: An unlimited size byte array specifying the EVM-code for the account initialisation procedure CREATE, data: An unlimited size byte array specifying the input data of the message call, formally Td.

eip712_meta: Option<Eip712Meta>

ZKsync-specific fields.

Implementations

impl TxEip712

pub const fn effective_gas_price(&self, base_fee: Option<u64>) -> u128

Returns the effective gas price for the given base_fee.

Trait Implementations

impl Clone for TxEip712

fn clone(&self) -> TxEip712

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxEip712

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

Formats the value using the given formatter.

impl Default for TxEip712

fn default() -> TxEip712

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TxEip712

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<TxEip712> for TransactionRequest

fn from(tx: TxEip712) -> Self

Converts to this type from the input type.

impl Hash for TxEip712

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TxEip712

fn eq(&self, other: &TxEip712) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for TxEip712

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl SignableTransaction<PrimitiveSignature> for TxEip712

fn set_chain_id(&mut self, chain_id: ChainId)

Sets chain_id.

fn encode_for_signing(&self, out: &mut dyn BufMut)

RLP-encodes the transaction for signing.

fn payload_len_for_signature(&self) -> usize

Outputs the length of the signature RLP encoding for the transaction.

fn into_signed(self, signature: Signature) -> Signed<Self>

Convert to a [Signed] object.

fn set_chain_id_checked(&mut self, chain_id: u64) -> bool

Set chain_id if it is not already set. Checks that the provided chain_id matches the existing chain_id if it is already set, returning false if they do not match.

fn encoded_for_signing(&self) -> Vec<u8>

RLP-encodes the transaction for signing it. Used to calculate signature_hash.

fn signature_hash(&self) -> FixedBytes<32>

Calculate the signing hash for the transaction.

fn is_create(&self) -> bool

Returns true if the transaction is a contract creation. We don’t provide a default implementation via kind as it copies the 21-byte [TxKind] for this simple check. A proper implementation shouldn’t allocate.
