Struct EthTransactionValidator 

Source 
pub struct EthTransactionValidator<Client, T> { /* private fields */ }
Expand description

A TransactionValidator implementation that validates ethereum transaction.

It supports all known ethereum transaction types:

  • Legacy
  • EIP-2718
  • EIP-1559
  • EIP-4844
  • EIP-7702

And enforces additional constraints such as:

  • Maximum transaction size
  • Maximum gas limit

And adheres to the configured LocalTransactionConfig.

Source§

impl<Client, Tx> EthTransactionValidator<Client, Tx>
where Client: ChainSpecProvider + StateProviderFactory, <Client as ChainSpecProvider>::ChainSpec: EthereumHardforks, Tx: EthPoolTransaction,

Source

pub fn block_gas_limit(&self) -> u64

Source

pub fn validate_one( &self, origin: TransactionOrigin, transaction: Tx, ) -> TransactionValidationOutcome<Tx>

Source

pub fn validate_one_with_state( &self, origin: TransactionOrigin, transaction: Tx, state: &mut Option<Box<dyn AccountInfoReader>>, ) -> TransactionValidationOutcome<Tx>

§

fn quirk(&self, value: Quirk) -> Painted<&T>
