Is CRO Ethereum based?

I'm curious about the technological backbone of CRO. Is it based on Ethereum? This question has been bugging me for quite some time as I'm trying to understand the intricacies of the crypto world. Ethereum, as we all know, is a highly respected platform that hosts numerous decentralized applications. If CRO indeed relies on Ethereum, it would be quite fascinating to know how it leverages the platform's capabilities. On the other hand, if it's not based on Ethereum, I'd be interested in knowing what other technology it employs. Could you please clarify this for me? It would greatly aid my understanding of the cryptocurrency ecosystem.
