Is Star Atlas on Solana?

Excuse me, I was wondering if you could clarify something for me. I've been hearing a lot about Star Atlas recently, and I understand it's a gaming metaverse project with a focus on space exploration. However, I'm not entirely sure about its blockchain foundation. Could you please tell me if Star Atlas is built on the Solana blockchain? I'm trying to gather more information on the project's technical infrastructure and I believe knowing this detail would be quite helpful. Thank you in advance for your assistance.
