Interview with MARKET Protocol, dYdX's CFL Integration, and New Launch Kit UIs

0x Ecosystem Update, June 2019

Hello 0x community! We’ve decided to retire the Relayer Report and rebrand our monthly update. Since the first edition of our newsletter in May 2018, the 0x ecosystem has grown beyond just relayers. There is now a diversity of projects in the ecosystem, which we intend to report on in this monthly recap going forward. We will be expanding our coverage of a variety of topics including 0x Network metrics, market making on DEXs, and new types of companies integrating with 0x. Let’s dive in!

General 0x Updates

dYdX and Contract-fillable Liquidity
We wrote up a case study about dYdX’s recent 0x integration. This integration is powerful in that it leverages contract-fillable liquidity (CFL), which describes the ability for smart contracts to programmatically swap tokens by filling orders on decentralized exchanges. 0x now has some of the lowest slippage compared to other DEX protocols (IDEX, Kyber, Uniswap, etc.) for popular pairs like ETH/DAI, ETH/USDC, DAI/USDC, BAT/ETH, and more. In addition to providing liquid markets for key trading pairs at all purchase prices, we have added new documentation to help developers easily tap into the 0x networked liquidity pool.

StarkDEX Demo
We released a demo of StarkDEX, a proof-of-concept technology developed in collaboration with StarkWare. StarkDEX is decentralized exchange infrastructure that utilizes STARKs to remove the glass ceiling on non-custodial trading and allows crypto exchanges to offer their customers trading at scale, without counter-party risk. Today, the system at max capacity can batch 8,000 transactions per block, which is over 550 transactions per second and 200x cheaper in terms of gas costs. Ethereum at max capacity can only verify roughly 3 transactions per second. Check out the demo here.

0x Launch Kit Reloaded
We launched version 2 of 0x Launch Kit. We designed a pair of off-the-shelf React UIs for both orderbook relayers and NFT marketplaces. Adding these new frontend templates enable developers and businesses to launch a marketplace in just 1 line of code! We also combined both frontend and backend components into a single Docker container that can be utilized to create your own decentralized exchange. Learn more here and get started creating your own marketplace here.

The Inaugural 0x Team Hackathon
In June, we hosted our first internal hackathon! We believe it is important to reserve time to explore creative ideas and hack on prototypes that have the potential to grow 0x and the greater crypto economy, even if they do not directly contribute to our quarterly company objectives. Creating an open environment where team members can discuss and build innovative technology is deeply embedded in our company culture and some of the key components of the 0x stack originated from Core Team members hacking in their spare time and bouncing ideas off each other.
This hackathon was intended to foster that innovative spirit and give team members the freedom to build whatever piqued their interest. Check out all the project submissions here.

Educational YouTube Videos
We are starting to work on revamping our YouTube channel. We have created a variety of video playlists intended to keep our community informed on 0x updates and assist developers with building on 0x. Check out some of our recent video series including:

Interview with MARKET Protocol

The MARKET Protocol team recently launched MPX, a decentralized derivatives exchange built on 0x. Bass Bauman, their Head of Business Strategy, was kind enough to answer some questions about the vision for their product and protocol.

Why did you and your team build MARKET Protocol?
We saw that the risk management tools we used as derivatives traders did not exist in the nascent crypto markets. We knew that crypto volatility would be a barrier to adoption, and we wanted to build something to help solve this problem, so we began working on what became MARKET Protocol, a solution that benefits hedgers, speculators and investors alike.

In layman’s terms, how does MARKET Protocol work?
MARKET Protocol enables users to mint tokenized derivative assets. For example, tokenized positions in Apple shares, YEN, or even leveraged relationships like 2x short Bitcoin. Smart contracts enforce the token rules so there is no counter-party risk, and tokens are ERC-20s so they can trade on any crypto exchange. 

Our first product is a BTC/DAI contract. There are two tokens: short BTC/DAI (sBTC) and long BTC/DAI (LBTC). If you buy sBTC, you profit when the price of Bitcoin goes down. If you buy LBTC, then you profit when the price of Bitcoin rises. Both tokens offer leverage, so you can earn more profit with the same amount of capital.
Last week, you guys released MPX, the first exchange utilizing MARKET Protocol. Congrats! How is the launch going so far?
Great so far! The official launch of MPX was Monday, June 24th. We saw nearly $60K of open interest within the first day, which was certainly more than we were expecting at launch. We’re very excited to have users on board now!

How did your team utilize 0x in building MPX?
To get started, we used the 0x Launch Kit, 0x.js and 0x Connect to interact with the 0x protocol, specifically the order watcher from the Launch Kit. We’re currently in the process of swapping out the order watcher for 0x Mesh. Our team is very excited about this upgrade!

What’s on the MPX roadmap for the rest of 2019?
It’s all about creating more opportunities for traders. Currently, we’re focused on listing more trading pairs for cross-chain assets like XRP, LTC, and EOS. Beyond crypto assets, we want to list an index of technology stocks, for example, FANGs. Next, we want to show off the flexibility of our protocol by creating totally new relationships like a token representing volatility in the crypto space, for example, a Crypto VIX. 

We are also focused on supporting the further adoption of Position Tokens. We expect tokens to be listed soon by a few other decentralized exchanges looking to offer cross-chain assets. We’re also exploring how to integrate Position Tokens with other DeFi protocols.

Our long term goal is to reduce MARKET Protocol’s reliance on external data sources, and for this reason, we are distributing the MKT token to traders and other users of the platform. Beginning later this year, we expect the community of token holders to assist in arbitration, settlement, and governance.
What is exciting to you about DeFi right now or the crypto space more generally?
We’re excited to finally see some traction in many applications. The amount of assets locked in DeFi protocols is starting to take off. A number of projects that have released second versions are starting to see hockey stick growth. In general, DeFi is becoming more usable and accessible, and the thawing crypto markets should provide a great tailwind. We look forward to what comes next!
