Is balancer on Ethereum?

Excuse me, could you please clarify if Balancer is indeed built on the Ethereum blockchain? I'm interested in understanding if its smart contracts and decentralized exchange capabilities are leveraging the security and decentralization of the Ethereum network. Additionally, if it's indeed on Ethereum, does it mean that users can interact with Balancer through Ethereum wallets and take advantage of the network's interoperability with other DeFi protocols?
