Verification client.

Required Methods

fn transaction_already_included(&self, hash: &H256) -> bool

Is transaction with given hash already in the blockchain?

fn verify_transaction(
    &self,
    tx: UnverifiedTransaction
) -> Result<SignedTransaction, Error>

Structurarily verify given transaction.

fn required_gas(&self, tx: &Transaction) -> U256

Estimate minimal gas requirurement for given transaction.

fn account_details(&self, address: &Address) -> AccountDetails

Fetch account details for given sender.

fn transaction_type(&self, tx: &SignedTransaction) -> TransactionType

Classify transaction (check if transaction is filtered by some contracts).

fn decode_transaction(
    &self,
    transaction: &[u8]
) -> Result<UnverifiedTransaction, Error>

Performs pre-validation of RLP decoded transaction
