Is Metis on ETH?

As a keen observer in the realm of cryptocurrencies and decentralized finance, I've noticed the emergence of Metis with its promise of enhanced scalability and interoperability. However, one question that remains unanswered for many is whether Metis is built on Ethereum (ETH), the second-largest blockchain network by market capitalization. Ethereum's robust infrastructure and active developer community have attracted numerous projects to its ecosystem, and it's crucial to understand Metis's positioning within this landscape. Could you please clarify if Metis is indeed based on Ethereum or if it operates independently on its own blockchain? This information is vital for investors, developers, and enthusiasts alike to make informed decisions regarding their involvement with this emerging project.
