Podcast: Building a decentralized exchange and appchain for perpetual contracts, with dYdX CEO Antonio Juliano

Hi Fintech Futurists —

Welcome back to our podcast series! For those that want to subscribe in your app of choice, you can find us at Apple, Spotify, or on RSS.

In this conversation, we chat with Antonio Juliano, founder and CEO of dYdX - a crypto derivatives trading platform that caters to professional traders outside the U.S. It averages roughly $2 billion in daily trading volume (Coinbase does about $5 billion)

After obtaining a computer science degree at Princeton University in 2015, Antonio started working at Coinbase as a software engineer, where he learned about cryptocurrency and the world of blockchain. He was fascinated by the new technology, especially after listening to some of the most prominent people in the space give talks at Coinbase, such as Vitalik Buterin and Polychain Capital founder Olaf Carlson-Wee.

Sneak Peek:

Antonio Juliano:
…Layer 2s are basically just more scalable blockchains that are built on top of another blockchain. And this is important because one of the biggest challenges in building in crypto is that things are really not scalable. So, I'll kind of walk through the specific story for dYdX and why we chose to build on a Layer 2, which is how dYdX works today. So, I think this was like 2020 or 2019 or so. There was a huge bull market in crypto. That was awesome. Finally, we're getting a ton more trading volume and stuff. But the problem was gas fees were through the roof on Ethereum. So, prior to this event happening, dYdX was just a smart contract on regular old Layer 1 Ethereum and you might have to pay a few cents to make a trade, which is okay because you're already probably paying more trading fees than that so who really cares if you're paying a few cents to make a given trade.

But the problem was the rate at which gas fees spiked was pretty insane, to be honest. And it got to the point where people were having to pay literally on the order of a hundred dollars to make a single trade on dYdX just because the gas fees were so high on Ethereum. And this was clearly not sustainable. Who's going to use an exchange where you have to pay a hundred dollars to make a single trade? Nobody. So, we thought a lot about this and it effectively pushed us to be one of the really big early adopters of Layer 2. And the specific Layer 2 that we're built on is called Stark-based rollup, or if you've heard the term like zero-knowledge rollups, it's very similar to that.

We're in partnership with a company called Stark, where right now, which is one of the big leaders in this kind of technology. And we moved dYdX from…
