Implementations§

Source§

impl<Client, Tx> OpTransactionValidator<Client, Tx>

Source

pub fn chain_spec(&self) -> Arc<Client::ChainSpec>
where Client: ChainSpecProvider,

Returns the configured chain spec

Source

pub fn client(&self) -> &Client

Returns the configured client

Source

pub fn require_l1_data_gas_fee(self, require_l1_data_gas_fee: bool) -> Self

Whether to ensure that the transaction’s sender has enough balance to also cover the L1 gas fee.

Source

pub const fn requires_l1_data_gas_fee(&self) -> bool

Returns whether this validator also requires the transaction’s sender to have enough balance to cover the L1 gas fee.

Source§

impl<Client, Tx> OpTransactionValidator<Client, Tx>
where Client: ChainSpecProvider<ChainSpec: OpHardforks> + StateProviderFactory + BlockReaderIdExt, Tx: EthPoolTransaction + OpPooledTx,

Source

pub fn new(inner: EthTransactionValidator<Client, Tx>) -> Self

Create a new OpTransactionValidator.

Source

pub fn with_block_info( inner: EthTransactionValidator<Client, Tx>, block_info: OpL1BlockInfo, ) -> Self

Create a new OpTransactionValidator with the given OpL1BlockInfo.

Source

pub fn with_supervisor(self, supervisor_client: SupervisorClient) -> Self

Set the supervisor client and safety level

Source

pub fn update_l1_block_info<H, T>(&self, header: &H, tx: Option<&T>)
where H: BlockHeader, T: Transaction,

Update the L1 block info for the given header and system transaction, if any.

Note: this supports optional system transaction, in case this is used in a dev setup

Source

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

Validates a single transaction.

See also [TransactionValidator::validate_transaction]

This behaves the same as OpTransactionValidator::validate_one_with_state, but creates a new state provider internally.

Source

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

Validates a single transaction with a provided state provider.

This allows reusing the same state provider across multiple transaction validations.

See also [TransactionValidator::validate_transaction]

This behaves the same as [EthTransactionValidator::validate_one_with_state], but in addition applies OP validity checks:

  • ensures tx is not eip4844
  • ensures cross chain transactions are valid wrt locally configured safety level
  • ensures that the account has enough balance to cover the L1 gas cost
Source

pub async fn is_valid_cross_tx( &self, tx: &Tx, ) -> Option<Result<(), InvalidCrossTx>>

Wrapper for is valid cross tx
