Is toshi on base network?

Could you clarify if Toshi is currently operating on a base network? I've heard varying opinions on this matter, and given the rapidly evolving nature of cryptocurrency and blockchain technology, it's important to stay informed. Some argue that Toshi is leveraging an established base network for scalability and reliability, while others maintain that it's operating on a standalone platform. I'd appreciate a concise yet comprehensive answer that addresses the current status of Toshi's network integration. Thank you.
