Struct EthPooledTransaction

Source 
pub struct EthPooledTransaction<T = TransactionSigned> { /* private fields */ }
Expand description

The default PoolTransaction for the Pool for Ethereum.

This type is essentially a wrapper around [RecoveredTx] with additional fields derived from the transaction that are frequently used by the pools for ordering.

Implementations§
