Is SushiSwap on Ethereum?

I'm curious, can you confirm whether SushiSwap is actually hosted on the Ethereum blockchain? I've heard conflicting information and would like to know for sure. With the ever-evolving landscape of decentralized finance and the emergence of new blockchains, it's important to stay informed about the platforms and protocols that are leading the way. If SushiSwap is indeed built on Ethereum, how does this impact its performance, scalability, and potential for growth in the future? I'm eager to learn more about the connection between SushiSwap and Ethereum.
