Enum EthereumTxEnvelope

pub enum EthereumTxEnvelope<Eip4844> {
    Legacy(Signed<TxLegacy>),
    Eip2930(Signed<TxEip2930>),
    Eip1559(Signed<TxEip1559>),
    Eip4844(Signed<Eip4844>),
    Eip7702(Signed<TxEip7702>),
}

The Ethereum EIP-2718 Transaction Envelope.

Note:

This enum distinguishes between tagged and untagged legacy transactions, as the in-protocol merkle tree may commit to EITHER 0-prefixed or raw. Therefore we must ensure that encoding returns the precise byte-array that was decoded, preserving the presence or absence of the TransactionType flag.

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<Eip4844>)

A TxEip4844 tagged with type 3. An EIP-4844 transaction has two network representations: 1 - The transaction itself, which is a regular RLP-encoded transaction and used to retrieve historical transactions..

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

Eip7702(Signed<TxEip7702>)

A TxEip7702 tagged with type 4.
