Relayer Report #16–0x Instant, Ecosystem Acceleration Program, and MyCrypto Interview

The latest updates from the 0x ecosystem: 12/18/18

Sign up for Relayer Report here

Relayer Report will be on break for the new year. The next issue will be released mid-January.

I’d like to introduce a new relayer, Bit2Me that is based in Madrid. Bit2Me got its start in 2014 by connecting Bitcoin with thousands of ATMs in Spain, letting anyone easily convert Bitcoin into cash. They’ll be fully launching soon, but here’s a sneak peek at their sleek interface:

I also saw that Proof of Work, the inspiration for Relayer Report, started implementing brief bios for each project. I thought this was a great idea, so going to start doing that here (h/t Eric Meltzer). We also have an updated logo made by our amazing designers Ben and Chris. 

This was a particularly crazy couple of weeks for 0x. We released 0x Instant: with a few lines of code, you can seamlessly add crypto purchasing to any app or website (Forbes coverage here). We unveiled our Ecosystem Acceleration Program, which will be awarding $1 million per year to high-quality teams to grow the 0x ecosystem (application here). Our Ecosystem Development Lead Clay released “22 Ideas to Explore with 0x”, which digs into the plethora of possible use cases for our protocol. And finally, former 0x relayer DDEX is moving to the Hydro protocol, with a response to this news from Will here.

Integrating Instant

So far Instant has been integrated into NFT marketplaces (Emoon), dApps (Augur), price feeds (CoinGecko), and wallets (Coinbase Wallet, Balance, MyCrypto) — for a sample walkthrough, check out our ecosystem engineer Jacob’s walkthrough. I sat down with Taylor Monahan of MyCrypto to interview her about MyCrypto’s Instant integration experience.

R: How was your integration experience with Instant? What were the pain points and tricky implementation details?

T: The experience was overall very positive. It could not have been easier to add the script and get it working. As far as pain points, the modal-only design necessitated a hacky solution to bring it inline — the 0x team was nice enough to facilitate this by adding a classname. The other tricky part was handling the content security policy ramifications, with their external fonts and analytics.

R: How does Instant fit into your long-term strategy?

T: We strive to provide our users with easy ways to interact with the blockchain and core protocols and platforms on the blockchain and we want to do so via a unified experience. Including a way to easily swap Ether for tokens has proven to be a valuable feature for our users, and adding a decentralized option alongside ShapeShift only adds value. This is only the first iteration of the integration and we hope to make the entire experience more unified and simpler over the coming months. Eventually, we plan to support many tools and ways of using the blockchain, so the variety is very helpful.

R: Where is wallet tech going? What improvements need to happen in the space to increase user adoption?

T: We need to vastly simplify just about everything in the blockchain / cryptocurrency ecosystem. Right now it’s so difficult for a new user to enter the space as it is filled with entirely new concepts and systems that they haven’t experienced before. Education is important, but creating easy-to-use products that reduce the amount of overhead for a user is equally important. 0x Instant is a perfect example of a system that takes a fairly traditional financial concept (trading), decentralizes it, and removes the complexity typically found within both centralized and decentralized financial tools.

R: How do you think the benefits of self-custody can better be communicated to the average user?

T: Unfortunately, I think one way people truly learn about the importance of self-custody is when the companies controlling their data or funds royally screw up. When we hear about another exchange hack or data breach we instantly understand the risks trusting a third-party with funds or information. We can obviously do better at communicating the value of decentralized systems proactively, but the fear or loss experienced when a company is breached is [un]fortunately highly effective.

Art on the Blockchain

One of the coolest parts for me working with the projects building on top of 0x is that there are quite a few verticals and industries being tackled since the protocol is so flexible. Blockchain-based art startups have been using 0x to facilitate the exchange of goods — this includes Pixura, the team behind SuperRare, a digital art auction, Magik Gallery, a platform for AR content creators to sell their art directly, and Maecenas, a marketplace for selling shares of real art.

Maecenas’ strategy is to tokenize real-world art and sell fractional ownership to as many people as possible. They made headlines in September when they sold a 31.5% stake of Andy Warhol’s piece “14 Electric Chairs” to 100 participants, raising $1.7 million in total. They will be selling a tokenized Picasso during the first quarter of 2019, selling ERC-20 tokens that represent a fraction of a unique ERC-721 (similar to our 0x ETHSF winner, Fungible Non-Fungible Tokens that I covered in RR #12).

Pixura, the parent company of SuperRare, lets anyone set up an NFT marketplace with ease. SuperRare, developed by the Pixura team, is a platform to sell rare digital art.


SuperRare published a post recently about “Auditable Social Metrics,” with the SuperRare team looking into how to measure the value of NFTs in different ways. Engagement data on the blockchain is also much more public and transparent than the status quo of opaque models like the big tech companies today. Currently, users can like and view different art on SuperRare, with this data eventually becoming much more robust and filterable (ex. View likes and views from Ethereum accounts with >5 transactions.)

Prediction market relayer Veil and SuperRare are working on a collaboration that will track the top 100 most valuable art pieces on SuperRare. Veil markets will then be used for people to bet on the price of each asset — crossovers everywhere.

Relayer Report #15—Harbor Launch, Building an NFT Marketplace on 0x

The latest updates from the 0x ecosystem: December 4th, 2018

Sign up for Relayer Report here

Happy December folks. My birthday is at the end of the month, so please feel free to give the gift of relayer updates to any unsuspecting family members on my behalf.

Last week 0x Tracker, a project that analyzes trades in the 0x ecosystem, was open sourced by its creator Craig Bovis, a longtime community member. (Prediction market relayer Veil also open sourced its code).  We also hired another engineer to the 0x Core Team, Xianny Ng who comes from Mapbox. Welcome Xianny!

Finally, we have decided to move our external communications with the community from Rocket Chat to Discord. While it’s more catered to developers, anyone from the 0x ecosystem can join our Discord here.

Harbor Launches

Harbor recently launched their security token platform, with the first investable project coming from the real estate arm of DRW, a trading firm based in Chicago. Minimum investments in “The Hub,” a student property near the University of South Carolina, start at $21,000, with 955 tokenized shares in total on the market.

What stood out to me in the announcement was the number of related cryptocurrency firms that are involved in the Harbor launch. Custody experts BitGo (who incidentally are venture-backed by DRW and David Sacks, advisor to 0x and Harbor) deal with custody, 0x relayer The Ocean among others will list these assets so they can be traded peer-to-peer and over-the-counter, and finally, the possibilities with other protocols are endless, as shown in Harbor’s tweet storm about their launch:

ERC20-compatible #securitytokens unlock exciting new possibilities. Real estate examples: create levered longs and shorts w/ @dydxprotocol, create baskets/ETFs w/ @Setprotocol, create margin loans w/ @makerdao #defi

This ability to leverage multiple protocols to build a new financial instrument is something that has really been picking up traction recently, like the ETHSF project Primotif that I talked about in RR 12:

Primotif lets users buy sets of Augur and dYdX short tokens to get balanced exposure to synthetic assets like the S&P500. Synthetic assets are “a mixture of assets that, when combined, have the same effect and value as another asset” (Source). In this case, Augur tokens track the underlying asset (S&P500) while the dYdX short tokens provide a hedge on the ETH/USD price. The bundling of these assets is made possible by Set Protocol, and finally the exchange of this set for Ether is done using 0x.

While this interoperability is really cool, why create security tokens in the first place? Immutability, cheaper fees, transparent settlement, less regulatory overhead, and global access all combining to increase liquidity and efficiency seems to be the value proposition of security tokens as well as the DeFi movement.

On Developing With 0x

NFT relayer Emoon published this post about building with 0x, giving some guidance on how to get started with the protocol. I particularly liked the “Gotchas” section at the end that listed tricky mistakes they encountered:

While the Emoon experience of integrating with 0x was positive, there were some gotchas for our particular use case that are worth calling out:

  1. @0x/subproviders Doesn’t Work With Angular 6 When Doing Production Builds For Client or Server. Read more here.

  2. Old Version of bignumber.js. Read more here.

  3. If using the forwarding contract, remember that the taker (aka the buyer) pays any forwarding fees, not the maker (seller). As such, one has to factor that fee into the amount of ETH sent to the forwarding contract. This works differently than many other smart contracts that do atomic swaps, like Crypto Kitties for example, which take the fee from the seller.

  4. Also, if using the forwarding contract, remember that the maker (the seller) gets paid in WETH. The buyer is nicely abstracted from WETH but the seller is not, which is important to communicate to sellers who may be surprised when their order is filled but their ETH balance remains unchanged.

  5. Reading the 0x contracts is quite tricky, because of all the includes and nested files. Best bet is to actually print them out so you can bounce around between includes.

As 0x has grown, there are more options and abilities for relayers, meaning more education needed for any new dev or community member. Posts like this do a lot for the ecosystem, so thanks to the Emoon team.

Relayer Report #14 — EtherDelta Ruling, Permissioned Liquidity Pools, and ERC dEX Interview

The latest updates from the 0x ecosystem: November 19th, 2018

Sign up for Relayer Report here

We have a few new relayers to announce — first we have Emoon, a peer-to-peer marketplace for crypto collectibles that also enables users to track and analyze the assets they’ve bought.

Hut34 is next, which is in the early stages of becoming a data marketplace relayer. The founders have worked on a variety of projects in the cryptocurrency space, including an easy-to-use cryptocurrency wallet, a stablecoin backed by the AUSD, and a version of wrapped BTC.

On the 0x side of things, we are excited to announce the 0x Launch Kit. We compare it to Wordpress, with anyone able to fork the Launch Kit and add token trading functionality to their project in a few steps.

EtherDelta Ruling

In case you missed it, the SEC charged EtherDelta creator Zach Coburn with a violation of federal securities law. Make sure to read 0x’s official statement, a regulatory update from Radar Relay, and OpenRelay’s take on the news.

The final order from the SEC is here, and worth reading.


-Coburn was ordered to pay $75,000 in penalty, and $313,000 in disgorgement plus interest, which brings the total to $388,000 (On a lighter note, at the end of the report the SEC details various payment options for Coburn, including paying by ACH transfer, check or mail. Obviously there’s no other way to do it, but paying SEC fines the same way you pay other things is a funny idea. Please Venmo the SEC @sec-gov)

-A lot of important dates in the report. 7/12/16: EtherDelta launches, 7/25/17: SEC releases DAO Report, 12/15/17: Coburn sells EtherDelta to foreign buyers. After the sale, EtherDelta was hacked and also announced an ICO — Spencer Noon talked about this in relation to the birth of ForkDelta a few months ago

-Lots of great links in the footnotes showing the SEC did their research, from linking to the ERC-20 spec on GitHub to Nick Szabo’s 1994 piece Smart Contracts. They also discuss maker / taker orders and even link to Coburn’s Reddit posts

There’s a lot more to be taken from this ruling, so check out this summary as well as a collection of resources below for those who want to dive deeper into the implications.

Resource List:

Compliance On The Blockchain

Back in April, Will released a post about compliant peer-to-peer trading, making use of the terms “permissioned token” and “permissioned liquidity pool.” Using a permissioned token, token issuers can enforce KYC / AML checks on any token transfers:

“Permissioned tokens place restrictions on transfers directly within a token’s contract code, limiting ownership to Ethereum addresses that meet certain requirements. Aside from transfer restrictions, these tokens can behave like any other ERC20 token that one may be familiar with. The most common implementation of a permissioned token is straight forward: every time the token’s transfer function is invoked, the token contract checks a Registry contract to see if the recipient is registered to a whitelist. The transfer will only complete successfully if the recipient is registered to that whitelist.”

A key part of 0x V2 was the introduction of filter contracts, which take 0x orders and check them to make sure they satisfy a set of conditions. With filter contracts, relayers can create permissioned liquidity pools, where a collection of 0x orders are only available to a select list of Ethereum addresses, thus allowing relayers to enforce KYC / AML on trades. OpenRelay is doing some work on this front with something called Order Pools:

“The idea of order pools is that we will create partitioned groups of orders within OpenRelay that have their own constraints in terms of what orders can be uploaded to the pool, and what orders should be visible through the pool.”

What’s also been popular lately in the relayer ecosystem has been Wyre, an API and SDK for compliance. Version 1 of Wyre is built specifically for decentralized exchanges — once a customer has entered her information, Wyre will mint an ERC-721 that verifies a user’s identity on-chain. This KYC token is universally accessible, meaning that each individual relayer would not need to create their own KYC token or process. The Wyre team compares this to the blue checkmark of Twitter, allowing a user to compliantly trade on a DEX. This “minter” role will initially be played by the Wyre team, but eventually, Wyre will have an open procedure for becoming a minter.

A key benefit of permissioned liquidity pools and Wyre is that market makers who need KYC / AML in order to comply with regulations can now do so. Wyre even has an an OTC trading team that will be market making on permissioned liquidity pools across decentralized exchanges.

Interview with ERC dEX’s Lindsey Renken

I asked longtime 0x ecosystem community member and CMO of ERC dEX Lindsey Renken a few questions about the progress of the 0x ecosystem thus far and the differences between relayer and protocol.

R: What it’s been like to watch the 0x ecosystem grow and mature?

L: I cannot really comment on the ecosystem as a whole, but my experience helping to operate a relayer has been really interesting. We have been around since the beginning, since 0x launched their V1 protocol. Radar and Paradex were the first to announce their presence in the ecosystem. We were just organizing our team at launch, but we announced our closed alpha shortly thereafter. It’s been a really interesting experience.. I’ve helped to found companies in different industries, biotech, travel, but my experience in crypto, and the 0x ecosystem, has been different because there are so many similar companies growing and competing so closely in parallel after this kind of “big bang” event. This phenomenon occurs whenever there is a significant innovation or market void discovered, and there is interest from a wide audience. We’ve seen this in other industries. When this happens, you get ideas from other teams, you see how you can be better, all in real time. It’s an exciting way to build a company, but it also means that you’re always on, 24/7, because you want to outpace the competition on every little thing. All companies have competitors, but this has been next-level.

R: How has the V2 experience been?

L: It’s been exciting to see V2 come out. Having developed a V1 product, V2 kind of allowed us to answer a lot of the questions and solve a lot of problems our users had been raising. We believe we’ve been able to develop a product that is easier and even better to use.

R: How does building a relayer compare to building a protocol?

L: Relayers have a unique experience because we share a protocol. We are competing with each other, but we’re also collaborating, especially those that are sharing liquidity. Because we’re built on 0x, we all want 0x to succeed, but we are also rooting for other relayers to succeed… so I would say it might be more similar than you think at this stage. We all have a shared goal: to help this market grow and mature.

R: How do you breakdown problems between what relayers need to solve and what 0x needs to solve?

Relayer Report #13 — Interview with Augur’s Joey Krug and Governance Experiments

The latest updates from the 0x ecosystem: November 2nd, 2018

Sign up for Relayer Report here

A few members from the 0x team are in Prague — say hello! The rest of us are enjoying the singing from San Francisco. If you’re at DevCon, you may have also seen DDEX’s poster in the Prague airport.

I’m also excited to introduce two new relayers building on top of 0x — Lake Trade and BlockSwap. Lake Trade is a team out of Toronto with no trading fees at the moment, so check them out. They eventually want to tackle roboadvising to become a crypto Wealthfront. Block Swap implements OTC functionality using 0x while also having a feature called Rooms, which lets communities of users transact peer-to-peer over any asset (be it CryptoKitty or niche ERC-20).

The Relayer Augur Needed

Last week I interviewed one of the co-founders of Veil, 0x’s first prediction market relayer, so I thought I’d get into Augur a bit this week, with a quick Q&A with 0x advisor Joey Krug below. I found a great profile about Augurreleased a few weeks ago, where I learned that the name Augur comes from Roman seers who could predict the future from reading the flight patterns of birds. Sounds like cool knowledge that could be used in some kind of Augur tattoo, which I looked up after I wrote this and actually found an Augur tattoo.

I also reviewed the Augur whitepaper and came across this paragraph: “All Augur assets — including shares in market outcomes, participation tokens, shares in dispute bonds, and even ownership of the markets themselves — are transferable at all times.” Any time I see the words asset and tradeable, I think relayer.

Q&A with Joey Krug of Augur

R: What’s exciting you the most in the Augur ecosystem?

J: The most exciting thing is just seeing people building on top of it to be honest! Seeing markets on celebrities’ success is pretty crazy and something I hadn’t seen before. An interesting vertical I haven’t seen targeted much would be markets on private companies, although the regulatory challenges for a company doing that would be hard.

R: What was your favorite project at ETHSF?

J: Augur Pro which was an iOS UI on top of Augur.

R: Augur was founded back in 2014, while 0x wasn’t founded until the end of 2016. There has been a lot of talk about prediction market relayers recently — did you envision some type of relayer-like vehicle for tradeable Augur assets when Augur was founded?

J: I thought people would build things on top similar to relayers, but of course didn’t know the term, and also hadn’t thought to do trading partially off-chain as a relayer way back then.

R: How would you compare and contrast Augur to more pure derivative projects (dYdX for example)?

J: dYdX is for derivatives on assets that exist on-chain as well as a protocol for margin. Augur is for everything, but probably best for assets that don’t exist on-chain. Since I believe blockchains will be a parallel financial system as opposed to the old one migrating over, I think there’ll be much more value in purely synthetic cash-settled contracts.

R: You had a great post about fees in Augur and how they’ll go down over time. Of the fees you mention in the article (fiat onramp, gas, volatility, market creator), which ones do you think will be the easiest to fix? Hardest?

J: On-ramp + volatility + creator fees will be the easiest, all fixable within the year. Gas costs and slowness of blockchains in general will take the longest.

R: What are you looking forward to in Augur V2?

J: Dai support mainly! As well as better UX that involves not needing to sync an app for hours haha.

Governance, Governance, Governance

Will and Peter presented “Building Self-Sustaining Ecosystems Through Governance” at DevCon. Our first governance experiment will be an elected committee of ZRX stakeholders who can decide where to allocate community funds. It’s important to note two things:

  1. This is an experiment (on a highly experimental technology that is built on top of another piece of highly experimental technology)

  2. The end goal is to decentralize power in the network and give ZRX stakeholders influence over how the protocol upgrades over time

Reading through this deck I was reminded of a picture from Chris Dixon’s article “Why Decentralization Matters”:

This S-curve has been the standard mode of operation for tech companies, but the 0x vision is to invert this, giving more and more power to stakeholders over time.


LedgerDex (Matt):

  • We have started supporting the EIP712 standard for typed message signing. Now when users use MetaMask to sign a new order, they will see the order details showing up on MetaMask

  • To prepare for MetaMask’s upcoming security upgrade (which will stop automatic injecting of Web3), we have updated our web app so that users can still use MetaMask smoothly after the change happens

  • We broke our record in daily trading volume: traded token value equivalent to USD $59,000 in a single day

DDEX (Diane):

  • Wallet connect feature in development: connecting desktop DDEX to mobile Wallets using end-to-end encryption by scanning a QR code

  • DDEX Wallet (iOSAndroid) selective test for recovery words feature in development

  • DDEX assists in the launch of WBTC (Wrapped Bitcoin Tokens) for bringing Bitcoin to Ethereum

Radar Relay (Beatrice):

  • sETH has arrived Radar Relay, read more about it on our educational site http://shorttokens.io

  • DNN token is now on Radar Relay

  • The market order handler has been updated and is now denominated in the quote token rather than the base token, take a look before you place your next order

STAR BIT (James):

  • STAR BIT EX 3.0 version and new homepage released with UI/UX renovated: STAR BIT EX

  • Support EIP-712 and we could check order detail before signature

  • STAR BIT EX 3.0 is able to set the trading pair based on different token or coin, such as SBT, DAI, TUSD

Bamboo Relay (Josh):

Instex (Tim):

  • Completing implementation of the SRA v2

  • Testing relayer before beta launch

Paradex (Katie):

  • Our team is busy at Devcon4 this week in Prague!

Veil (Paul):

OpenRelay (Greg):

The Ocean (Monica):

  • We’re hard at work revamping all things The Ocean! If you’d like to help provide feedback or contribute to our developer portal, reach out to us at hello@theocean.trade

  • Our CEO, John, joined the Wyre team for their Wyre Talks podcast. Give it a listen to learn more about the infrastructural risk inherent in traditional finance and how cryptocurrency can be the solution


Product Marketing AssociateTechnical Support Associate @ Radar Relay


Gluon Plasma: A Plasma Variant for Non-custodial Exchanges (Bharath Rao):

A company called Leverj, dubbed the decentralized leverage exchange, released their white paper recently, with the idea of using plasma sidechains for a high speed, low latency decentralized exchange.

Dex Research (Gnosis):

This Gnosis spec goes over a new kind of DEX design that involves batch transactions and STARKS.

WBTC: A Community Effort to Bring Bitcoin to Ethereum (Loi Luu):

Introducing Wrapped BTC, a collaborative effort by Kyber, BitGo, and Republic (with DDEX and Radar Relay as launch partners, among others.) All WBTC is fully collateralized by BTC, with atomic swapping between WBTC and BTC. While still very early, great to see more experiments on the cross-chain side of things.

Cute Cats Power Serious $15 Million Funding for CryptoKitties Creators(CoinDesk):

Dapper Labs (creators of CryptoKitties) raised another $15 million in funding, bringing its total to nearly $30 million. These are some phat cats. dYdX also raised a $10 million Series A with some of the best investors in the space.

How I Learned to Start Analyzing and Stop Building Inscrutability (Philip Daian):

Philip from IC3 tears apart security in decentralized exchanges (among other things), pointing out problems in front running, cancellations, and gas costs.

Fun Stuff

I read a really interesting interview with early free software pioneer Richard Stallman.

If you know anything about you me, you know I love watching documentaries on YouTube. Check out Nosebleed about the world of high stakes poker, and The Smash Brothers about the competitive gaming scene of Super Smash Bros Melee.

A tale of car companies and short sellers getting squeezed — Elon would love this.
