What are the top DeFi derivatives?

Could you please elaborate on the topic of DeFi derivatives? I'm particularly interested in understanding what the top ones are in the current market scenario. Could you name a few and explain what makes them stand out? Also, would you mind sharing insights into their functionality, potential risks, and any specific advantages they might offer to investors? Additionally, are there any regulatory considerations or recent developments that investors should be aware of? Thank you for your assistance in clarifying this important aspect of the DeFi landscape.
