What network is AAVE on?

Could you please clarify for me which blockchain network AAVE is currently operating on? I'm trying to understand the technical foundation of this decentralized finance protocol and its integration within the larger crypto ecosystem. Is AAVE built on Ethereum, or perhaps another platform? I'm interested in knowing the specific network it leverages for its smart contracts and transactions, as this information is crucial for assessing its scalability, security, and interoperability. Thank you for your assistance in answering this question.
