Does pancake support Ethereum?

Excuse me, I was wondering if you could clarify something for me. I've been hearing a lot about PancakeSwap and its popularity in the decentralized finance space. However, I'm a bit confused about its compatibility with other blockchains. Specifically, does PancakeSwap support Ethereum transactions or is it strictly limited to Binance Smart Chain? I'm asking because I'm interested in using PancakeSwap but I also have some Ethereum-based assets that I'd like to trade. Could you please shed some light on this matter? Thank you in advance for your help.
