Enum PooledTransaction

Expand description

All possible transactions that can be included in a response to GetPooledTransactions. A response to GetPooledTransactions. This can include either a blob transaction, or a non-4844 signed transaction.

The difference between this and the TxEnvelope is that this type always requires the TxEip4844WithSidecar variant, because EIP-4844 transaction can only be propagated with the sidecar over p2p.
