Coordinators, Stablecoin Trading Growth, and an Interview with dYdX

Ecosystem Update, July 2019

Hello 0x community! Over the past month, we saw a significant increase in stablecoin liquidity flowing into the 0x Network, in addition to a variety of new projects launching in the ecosystem. We’ll dig into both of those topics and more in this monthly update!

General 0x Updates

0x Mesh Beta Release
0x Mesh is now live on mainnet! Mesh is a p2p network for receiving and sharing orders throughout the 0x ecosystem. One exciting aspect of Mesh is the ability to launch a serverless relayer, which doesn’t require a backend server and enables the frontend to be hosted on IPFS! Mesh is a critical layer in the 0x stack, as it will increase network liquidity and further decentralize 0x overall.

To quickly deploy your own Mesh node and join the network, take a look at our guide on Github.

Introducing Coordinators
A Coordinator is a service that enforces rules over trade execution for a specific pool of 0x liquidity. They may be operated as independent services or bundled together with a relayer. Coordinators combine the best characteristics of Order Matching and Open Orderbook relayer models: market makers can perform free, instant order cancellations and users/devs can leverage contract-fillable liquidity (CFL) to power independent Ethereum applications.

The first Coordinator demo implementation is live on Bamboo Relay, where you can find the best prices for DAI and WBTC across all DEXs. Try it out now!
 
ZRX Tokenholders Approved ZEIP-24 and ZEIP-39
We conducted a vote in July to determine whether or not to add support for the ERC-1155 token standard (ZEIP-24) and the StaticCallAssetProxy (ZEIP-39). Both proposals were approved by the community of ZRX token holders. Over 12.3 million ZRX were cast by 130+ unique addresses. Both ZEIPs will be implemented on mainnet next week!

v2.0 Exchange Contract Vulnerability Post-mortem
On July 12, we were made aware of a potential exploit in the 0x v2.0 Exchange contract by samczsun, a third-party security researcher. The vulnerability would allow an attacker to fill certain orders with invalid signatures. After verifying the vulnerability internally, the 0x Core Team triggered an emergency shutdown mechanism within 0x protocol’s system of smart contracts, preventing the vulnerability from being exploited. Historical trade logs confirm that the vulnerability had not been exploited prior to its discovery and disclosure. Subsequently, a patched version of the smart contract system (0x v2.1) was deployed to the Ethereum mainnet. The initial announcement may be found here.
 
We wrote up a post-mortem that recaps the details of the vulnerability and discussed a variety of topics including the role of the 0x Core Team and our views on decentralization.

New Explainer Video | What is 0x?
We were thrilled to release a new explainer video that we worked on with Sandwich Video. The Core Team has created a ton of new video content to help businesses, developers, and community members better understand the 0x protocol. So subscribe and check out our revamped YouTube channel to view technical walkthroughs, interviews, dev calls, and more!

0x Network Data

0x Network trade volume was up 6%+ month-over-month (MoM) and the top relayer, Radar Relay, had an eye-popping 142% monthly increase. Most notably though, USDC and DAI trade volumes were up 172% and 95% respectively in July! Let’s dive into the data.

  • Fill count: 28,233 (+41% MoM)

  • Fill volume: $30,911,184 (+8.7% MoM)

  • Trade count: 24,384 (+22% MoM)

  • Trade volume: $30,170,429 (+6% MoM)

  • Unique makers: 649

  • Unique takers: 645

  • Unique addresses: 1,079

Top Tokens

We calculated volume using both canonical and Ethfinex wrapper tokens. Note that volume exceeds total fill volume due to the two-sided nature of trades.

  • ETH: $23,741,419.10 (-7% MoM)

  • DAI: $14,664,631.26 (+95% MoM)

  • USDT: $10,068,414.87 (-25% MoM)

  • USDC: $6,690,354.93 (+172.6% MoM)

Top Relayers

  • Radar Relay: $16,968,758 (+142% MoM)

  • Tokenlon: $9,154,726 (-30% MoM)

  • Ethfinex: $3,283,336 (-48% MoM)

  • Paradex: $522,665.56 (-49% MoM)

  • Tokenmon: $170,227.58 (-78% MoM)

Ecosystem Highlights

  • Bit2Me, a Spain-based ERC-20 token relayer, launched last week! We are excited to see teams expand to service a variety of geographies.

  • Bazaaar.io, a Japan-based NFT relayer, launched last week as well! They also built a custom set of 0x extension contracts that enabled them to offer new ways of exchanging non-fungible tokens. Check out their announcement blog post here.

  • Microsponsors published a great article on why blockchains are ideal for creating trust-minimized marketplaces for sponsors and advertisers. Check out their blog post here.

  • We are excited to support the CheezeWizards online hackathon! We look forward to working with teams to bring their ideas to life and offer up a $2k prize to the project that best utilizes the 0x protocol! Hackers can learn more here about how 0x can facilitate p2p token exchange in their projects.

  • We are currently investigating alternative ways Korean users can interact with online wallets (and even the jump to hardware wallets) when using our Relayer. As there are different age demographics that we target for specific parts of our platform, and therefore the type of web client used by each is dramatically different. Further, depending on the web client used, browser extension education is actually a very important part of the process.
