@dataclass
class PayloadAttributes(object):
    timestamp: uint64
    prev_randao: Bytes32
    suggested_fee_recipient: ExecutionAddress
    withdrawals: Sequence[Withdrawal]
    parent_beacon_block_root: Root
    target_blobs_per_block: uint64  # [New in Electra:EIP7742]
    max_blobs_per_block: uint64  # [New in Electra:EIP7742]
```
