Does Ankr run on Ethereum?

Excuse me, could you clarify something for me? I was wondering, does the platform known as Ankr operate specifically on the Ethereum blockchain? I've heard a lot about its potential for decentralized finance and cloud computing services, but I'm unsure if its architecture is inherently tied to the Ethereum network. Could you please elaborate on this matter, and if it's not solely reliant on Ethereum, could you mention any other blockchain platforms it might integrate with?
