Function: createBlob4844TxFromBytesArray()

createBlob4844TxFromBytesArray(values, opts): Blob4844Tx

Create a Blob4844Tx transaction from an array of byte encoded values ordered according to the devp2p network encoding. Only canonical format supported, otherwise use createBlob4844TxFromSerializedNetworkWrapper().

Parameters

values

BlobEIP4844TxValuesArray

Array of byte encoded values containing:

chainId - Chain ID as Uint8Array
nonce - Transaction nonce as Uint8Array
maxPriorityFeePerGas - Maximum priority fee per gas (EIP-1559) as Uint8Array
maxFeePerGas - Maximum fee per gas (EIP-1559) as Uint8Array
gasLimit - Gas limit for the transaction as Uint8Array
to - Recipient address as Uint8Array (optional for contract creation)
value - Value to transfer in wei as Uint8Array
data - Transaction data as Uint8Array
accessList - Access list for EIP-2930 as Uint8Array (optional)
maxFeePerBlobGas - Maximum fee per blob gas (EIP-4844) as Uint8Array
blobVersionedHashes - Versioned hashes for blob validation as Uint8Array[]
v - Signature recovery ID as Uint8Array (for signed transactions)
r - Signature r component as Uint8Array (for signed transactions)
s - Signature s component as Uint8Array (for signed transactions)

opts

TxOptions = {}

Transaction options including Common instance with KZG initialized

Returns

Blob4844Tx

A new Blob4844Tx instance

Throws

If KZG is not initialized in Common

Throws

If values array length is not 11 (unsigned) or 14 (signed)

Format: [chainId, nonce, maxPriorityFeePerGas, maxFeePerGas, gasLimit, to, value, data, accessList, maxFeePerBlobGas, blobVersionedHashes, v, r, s]

Notes:

Requires a Common instance with customCrypto.kzg initialized
Supports both unsigned (11 values) and signed (14 values) transaction formats
All numeric values must be provided as Uint8Array byte representations
