Does serum really work?

I've been hearing a lot about Serum lately, and I'm curious if it truly delivers on its promises. As someone who's invested in cryptocurrency and finance, I need to know if Serum's decentralized exchange platform can truly offer faster transactions, lower fees, and better liquidity compared to other existing options. Can you elaborate on the technology behind Serum and how it differs from its competitors? Additionally, what are some potential risks or drawbacks that investors should be aware of before diving in? I'm eager to learn more about this emerging player in the crypto space.
