For today’s episode, I sat down with Su Zhu to learn all about perpetual swaps. There’s probably not a person in crypto who has more authority on this topic than him. The first half of the episode serves as a general introduction to perpetual swaps, while in the second half, we explore how perpetual swaps are coming to DeFi and why they are the single biggest primitive that is still missing from the DeFi puzzle. While the episode can get pretty technical at times, we tried to follow a logical buildup, so no prior knowledge should be required. Please note that I put some links to definitions and followup reading into the show notes. Enjoy the episode.
