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
