Is Pendle on Ethereum?

Could you please clarify for me whether Pendle is built on the Ethereum blockchain? I've been hearing a lot about it recently and I'm trying to understand its underlying technology. Is it a smart contract deployed on the Ethereum network, or does it utilize a different blockchain entirely? I'm particularly interested in its compatibility with other Ethereum-based projects and tools. Could you also elaborate on any potential advantages or disadvantages of Pendle being on Ethereum, if indeed it is? Thank you for your help in clarifying this matter.
