Is DAI based on Ethereum?

I'm curious, is DAI actually based on Ethereum? I've been hearing a lot about DAI and its stablecoin properties, but I'm not entirely sure about its technological foundation. Given the popularity and widespread use of Ethereum in the crypto world, it seems like a logical choice for DAI's underlying blockchain. But I'd like to know for certain. Could you clarify if DAI is indeed built on Ethereum, and if so, what are the advantages of this choice? I'm really interested in understanding the technological nuances behind DAI and its integration with Ethereum.
