Function: createBlob4844Tx()

createBlob4844Tx(txData, opts?): Blob4844Tx

Instantiate a Blob4844Tx transaction from a data dictionary.

If blobs are provided the tx will be instantiated in the “Network Wrapper” format, otherwise in the canonical form represented on-chain.

Transaction data object containing:

chainId - Chain ID (will be set automatically if not provided)
nonce - Transaction nonce
maxPriorityFeePerGas - Maximum priority fee per gas (EIP-1559)
maxFeePerGas - Maximum fee per gas (EIP-1559)
gasLimit - Gas limit for the transaction
to - Recipient address (optional for contract creation)
value - Value to transfer in wei
data - Transaction data
accessList - Access list for EIP-2930 (optional)
maxFeePerBlobGas - Maximum fee per blob gas (EIP-4844)
blobVersionedHashes - Versioned hashes for blob validation
v, r, s - Signature components (for signed transactions)
blobs - Raw blob data (optional, will derive commitments/proofs)
blobsData - Array of strings to construct blobs from (optional)
kzgCommitments - KZG commitments (optional, derived from blobs if not provided)
kzgProofs - KZG proofs (optional, derived from blobs if not provided)
networkWrapperVersion - Network wrapper version (0=EIP-4844, 1=EIP-7594)

Transaction options including Common instance with KZG initialized

A new Blob4844Tx instance

If KZG is not initialized in Common

If both blobsData and blobs are provided

Notes:

Requires a Common instance with customCrypto.kzg initialized
Cannot provide both blobsData and blobs simultaneously
If blobs or blobsData is provided, kzgCommitments, blobVersionedHashes, and kzgProofs will be automatically derived
KZG proof type depends on EIP-7594 activation: per-Blob proofs (EIP-4844) or per-Cell proofs (EIP-7594)
