Enum TxEip4844Variant

pub enum TxEip4844Variant<T = BlobTransactionSidecar> {
    TxEip4844(TxEip4844),
    TxEip4844WithSidecar(TxEip4844WithSidecar<T>),
}

EIP-4844 Blob Transaction

A transaction with blob hashes and max blob fee. It can either be a standalone transaction, mainly seen when retrieving historical transactions, or a transaction with a sidecar, which is used when submitting a transaction to the network and when receiving and sending transactions during the gossip stage.

Variants

TxEip4844(TxEip4844)

A standalone transaction with blob hashes and max blob fee.

TxEip4844WithSidecar(TxEip4844WithSidecar<T>)

A transaction with a sidecar, which contains the blob data, commitments, and proofs.
