EthTransactionValidator

reth_transaction_pool::validate

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.

Implementations§

Source§

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

Source

pub fn block_gas_limit(&self) -> u64

Returns the current max gas limit

Source

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

Validates a single transaction.

See also TransactionValidator::validate_transaction

Source

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

Validates a single transaction with the provided state provider.

This allows reusing the same provider across multiple transaction validations, which can improve performance when validating many transactions.

If state is None, a new state provider will be created.

pub fn validate_sender_nonce( &self, transaction: &Tx, sender: &Account, ) -> Result<(), InvalidPoolTransactionError>

Checks if the transaction nonce is valid.

Source

pub fn validate_sender_balance( &self, transaction: &Tx, sender: &Account, ) -> Result<(), InvalidPoolTransactionError>

Ensures the sender has sufficient account balance.

Source

pub fn validate_eip4844( &self, transaction: &mut Tx, ) -> Result<Option<BlobTransactionSidecarVariant>, InvalidPoolTransactionError>

Validates EIP-4844 blob sidecar data and returns the extracted sidecar, if any.
