0x Community Spotlight: Joey Zacherl, Founder of VolleyFire

An interview with a leading 0x market maker.

If you’ve been following our project, you would probably recognize at least a few of the many apps that have built on 0x. Unless you’ve been staking, however, you would not likely recognize any of our 0x market makers. Market makers are crucial players in the ecosystem. They supply a significant portion of the network’s liquidity, allowing 0x integrators and end-users to enjoy a vast selection of tokens, at the best prices. Their collective efforts have fueled the ecosystem’s growth, and our revised v3 network economics ensure that they are appropriately rewarded for their contributions. Despite the importance of their role in the ecosystem, 0x market makers remain somewhat of a mystery — both in terms of who they and what they do. With this spotlight, we look forward to shedding some light on our hard-working community of market makers. We hope you enjoy the interview below!

Please share a little bit about yourself and your background.

I’m a software engineer who loves building things. I got started in automation by building IoT (Internet of Things) automation platforms, video game bots, and online poker bots. VolleyFire has been my most successful automation venture by far. I followed Bitcoin during the early days and took the career plunge a few years after Ethereum went live. My fascination with the concept of decentralized trade stems back to the 2014 Mt. Gox incident. Witnessing those events play out demonstrated to me the value of trustless exchange.

What inspired you to build VolleyFire, and where did the name come from?

My first experience with decentralized exchanges came when I stumbled upon EtherDelta in 2017. The UI/UX was lacking, but the fundamentals were there. Anyone with an internet connection and an Ethereum wallet could trade without being exposed to 3rd party risk. It was brilliant for its time, but it suffered from a major flaw → a lack of liquidity. The order books were barren wastelands. ERC20 tokens were exploding with popularity, but it was impossible to find a trading partner. I quickly switched my focus to trading and market making on Ethereum to fill the liquidity gap and provide users with an automated trading partner.

The name VolleyFire comes from my approach to trading. I start by repeatedly firing volleys of trades and strategies at the market. Then, I observe to see what works and what doesn’t. Finally, I optimize, adjust, upgrade, and fire another volley.

Why did you decide to market make on 0x?

Early on, I chose 0x because it addressed all of the issues with EtherDelta. 0x was launched by a core of smart people with heads in the right places. I was impressed by the team’s focus on the protocol, UI/UX, scalability, and especially how they embraced the variety of users in the space by enabling both open order book and off-chain order matching. Today, I’m excited about how 0x Labs supports market makers with staking pools and how they embrace decentralized governance.

We recently announced a new Request for Quote (RFQ) trading system that enables market makers to bring centralized exchange liquidity directly to DEX and DeFi traders. What are your thoughts on it?

It’s fantastic both from a user’s perspective and from a market maker’s perspective. The user interface is incredibly easy and convenient to use. It responds with quotes much quicker than other order book aggregators, and the liquidity behind it is massive. 0x Labs wants to push 0x market makers to be the best, but they don’t hesitate to route your trade through other protocols if they’re offering better trade prices. When you’re trading over the 0x RFQ, you’ll get immediate access to not only VolleyFire’s liquidity but also Curve, Uniswap, Balancer, Kyber, etc.

Not only does the 0x Labs team provide an extremely simple and easy-to-integrate API, but they also provide a suite of visually interactive web tools to help market makers maintain a high-quality RFQ experience. These tools enable you to test your RFQ server, view response times, compare prices, view failed fill attempts, and even see where your fills are coming from and across which markets. The 0x team is dedicating themselves to making the best RFQ liquidity aggregator in the DeFi space.

What trading strategies do you regularly employ, and which tokens do you find most profitable to trade?

Over the years, I’ve implemented a wide variety of trading strategies, both on-chain and off. The majority of them provide liquidity to on-chain protocols like 0x. Some of my trading strategies exist purely for generating profit, while others serve a purpose based on the protocol’s functionality. Some of them are arbitrage based, while others are a bit more complex and typically volatility based.

I try to trade tokens that are in high demand. During 2017 and 2018, the market couldn’t get enough token variety. Then around 2018–2019, the market shifted heavily in favor of USD stable coins. Today, USD stable coins and DeFi-related tokens are all the rage. Any project involving yield generation is hot right now.

Your staking pool currently shares the highest % of staking rewards. What drove your decision to increase the %?

I value everyone who makes up the crypto community for two primary reasons.

1) I was the average crypto/DeFi community member for years before building on Ethereum and becoming a DeFi contributor.

2) All projects will fail without a thriving community.

I strive to have the highest effective share % to enable the community to thrive. I hope that this also encourages other staking pools to increase their share %, which in turn makes the community even stronger and creates a growth ripple effect for the 0x network as a whole.

There seems to be a limited number of companies focusing on DEX market making. Why do you think that is and how do you see this changing in the future?

DEX market making is challenging and requires a significant commitment from both a technical and financial perspective. If it were easy and convenient, there would be thousands of companies with new ones popping up every day. Though that’s not yet the case, I believe it’s not that far off.

Today, market makers are required to be skilled in automation software development, trading, and DevOps. Also, market makers must obtain large quantities of capital and be comfortable with the incredibly high volatile crypto assets. I’ve noticed some market makers don’t have an appetite for volatility, stick to stable coins, and hedge their non-stable coin assets. In contrast, other market makers take the volatility challenge head-on. Both are good strategies.

As software tools continue to grow and evolve, we’ll see the technical barrier of entry for market makers continue to decline. And as the crypto markets continue to mature, we’ll see more capital flowing confidently into the space.

What advice do you have for anyone who is considering market making on 0x?

Go for it. Jump right into the deep end. There’s no better time to start than today. You’ll be glad you did two years from now.

What other projects are you most excited about?

I’m thrilled about KeeperDAO where we are building an efficient mechanism for traders and liquidity providers to pool together and capture on-chain arbitrage and liquidation events. I’m also a huge fan of Set TokenSets, enabling anyone to have an automated trading strategy by merely buying and holding a single token. The sets manage multiple assets and rebalance for you according to the strategy you select. Both of these projects interact with 0x one way or another and demonstrate the 0x protocol’s versatility.

What do you enjoy doing in your free time?

I love animals, especially dogs. I enjoy ice hockey, card games, and RC car racing. I enjoy playing Texas hold ’em in live cash games, and I enjoy casual card games with family and friends as well.

Thanks for sharing Joey — we sincerely appreciate your contributions in enabling the healthy growth of the 0x and greater DeFi ecosystem! 📈
