Details of a signed transaction

Fields

hash: H256

The transaction’s hash

nonce: U256

The transaction’s nonce

block_hash: Option<H256>

Block hash. None when pending.

block_number: Option<U64>

Block number. None when pending.

transaction_index: Option<U64>

Transaction Index. None when pending.

from: H160

Sender

to: Option<H160>

Recipient (None when contract creation)

value: U256

Transferred value

gas_price: Option<U256>

Gas Price, null for Type 2 transactions

gas: U256

Gas amount

input: Bytes

Input data

v: U64

ECDSA recovery id

r: U256

ECDSA signature r

s: U256

ECDSA signature s

transaction_type: Option<U64>

Transaction type, Some(2) for EIP-1559 transaction, Some(1) for AccessList transaction, None for Legacy

access_list: Option<AccessList>

max_priority_fee_per_gas: Option<U256>

Represents the maximum tx fee that will go to the miner as part of the user’s fee payment. It serves 3 purposes:

1. Compensates miners for the uncle/ommer risk + fixed costs of including transaction in a block; 2. Allows users with high opportunity costs to pay a premium to miners;
2. In times where demand exceeds the available block space (i.e. 100% full, 30mm gas), this component allows first price auctions (i.e. the pre-1559 fee model) to happen on the priority fee.

More context here

max_fee_per_gas: Option<U256>

Represents the maximum amount that a user is willing to pay for their tx (inclusive of baseFeePerGas and maxPriorityFeePerGas). The difference between maxFeePerGas and baseFeePerGas + maxPriorityFeePerGas is “refunded” to the user.

chain_id: Option<U256>

other: OtherFields

Captures unknown fields such as additional fields used by L2s

Implementations

impl Transaction

pub fn hash(&self) -> H256

pub fn rlp(&self) -> Bytes

pub fn recover_from(&self) -> Result<H160, SignatureError>

Recover the sender of the tx from signature

pub fn recover_from_mut(&mut self) -> Result<H160, SignatureError>

Recover the sender of the tx from signature and set the from field

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.

impl Decodable for Transaction

Get a Transaction directly from a rlp encoded byte stream

fn decode(rlp: &Rlp<'_>) -> Result<Transaction, DecoderError>

Decode a value from RLP bytes

impl Default for Transaction

fn default() -> Transaction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Transaction

fn deserialize<__D>(
    __deserializer: __D
) -> Result<Transaction, <__D as Deserializer<'de>>::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<Transaction> for Transaction

fn eq(&self, other: &Transaction) -> 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 Transaction

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

Serialize this value into the given Serde serializer.
