Type Alias PooledTransaction

pub type PooledTransaction = EthereumTxEnvelope<TxEip4844WithSidecar>;

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.

Aliased Type

enum PooledTransaction {
    Legacy(Signed<TxLegacy>),
    Eip2930(Signed<TxEip2930>),
    Eip1559(Signed<TxEip1559>),

Variants

Legacy(Signed<TxLegacy>)

An untagged [TxLegacy].

Eip2930(Signed<TxEip2930>)

A [TxEip2930] tagged with type 1.

Eip1559(Signed<TxEip1559>)

A [TxEip1559] tagged with type 2.

Eip4844(Signed<TxEip4844WithSidecar>)

2 - The transaction with a sidecar, which is the form used to send transactions to the network.

A [TxEip7702] tagged with type 4.
