Is Jupiter crypto layer 2?

Excuse me, I'm curious about the status of Jupiter in the cryptocurrency landscape. Could you clarify if Jupiter is considered a Layer 2 solution within the crypto ecosystem? If so, what specific features or benefits does it offer as a Layer 2 protocol, and how does it compare to other popular Layer 2 platforms? Alternatively, if Jupiter is not a Layer 2 solution, could you elaBORAte on its primary function and how it fits into the broader crypto industry? 感謝您的時間和專業知識。
