Function: createBlob4844TxFromRLP()

createBlob4844TxFromRLP(serialized, opts): Blob4844Tx

Instantiate a Blob4844Tx transaction from an RLP serialized transaction. Only canonical format supported, otherwise use createBlob4844TxFromSerializedNetworkWrapper().

Parameters

serialized

Uint8Array

RLP serialized transaction data as Uint8Array

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 serialized data is not a valid EIP-4844 transaction

Throws

If RLP decoded data is not an array

Format: 0x03 || rlp([chain_id, nonce, max_priority_fee_per_gas, max_fee_per_gas, gas_limit, to, value, data, access_list, max_fee_per_blob_gas, blob_versioned_hashes, y_parity, r, s])

Notes:

Requires a Common instance with customCrypto.kzg initialized
Transaction type byte must be 0x03 (BlobEIP4844)
RLP payload must decode to an array of transaction fields
Delegates to createBlob4844TxFromBytesArray for actual construction
