Relayer Report is moving to a monthly format! I say that with a heavy heart, but I am scaling back my thought leadership to focus on fewer but higher quality issues.

0x Recap

Ethfinex Moving to V2

Ethfinex, a first of its kind, hybrid relayer is moving to 0x V2! Ethfinex’s model is pretty interesting in that it gives users access to the liquidity of its sister centralized exchange Bitfinex, while keeping the secure, wallet-to-wallet trading functionality of a 0x relayer. Ethfinex had a few reasons for the switch:

  • ERC721 compatibility, meaning greater scope and flexibility with tokens getting added to the exchange

  • Increased reliability and speed with new, streamlined order-data formatting

  • The inclusion of a new signature type, bringing with it two main end-user improvements: more human readable data shown in Metamask when signing a message and more order creation flexibility for contracts

  • Easier integrations with the wider 0x ecosystem as a whole

Ethfinex also recently celebrated its first birthday, now a group of 25 located largely in London but having remote members in Copenhagen, Switzerland, Prague, and elsewhere. On the liquidity side, Ethfinex’s top token pair is ETH/USDT, with other Dai pairs gaining popularity as well. Stablecoins are a huge interest for traders at the moment due to various arbitrage opportunities.

Finally, easier wallet integration remains a focus for the team moving forward, with Ethfinex CEO Will presenting at ETHCC and highlighting the high friction of the current wallet landscape. Ethfinex has enabled a range of popular wallets on their platform, including Ledger, Trezor, MetaMask and Portis.

Tokenary Interview

I sat down with Tokenary, the winner of the 0x + CoinList Hackathon for a few questions about their team and project. Tokenary built a way to trade NFTs over Bluetooth and WiFi.

Q: What is your team’s background? How did you end up interested in cryptocurrency, 0x, and NFTs?

Our five-person team is purely technical. When we first started using the Ethereum network in 2016, we faced many usability problems common to new technologies. In an attempt to address them, during the Qtum hackathon in Moscow in the summer of 2017, our team developed a prototype of a simple wallet application. After that, we started experimenting with different product features to make interactions with Ethereum as simple as possible but without compromising on trust and security. We started exploring NFTs with the release of Crypto Kitties and developed a native interface for tokenized collectibles back in early 2018. We also experimented with different trading features and that’s one of the reasons why we come up with a P2P idea.

Q: What are a few of Tokenary’s use cases? Do you have plans to continue the project?

Tokenary is a user-friendly way to interact with DApps across different devices. We provide three options for that:

- A brand new Safari Web3 extension

- Tokenary DApp browser for iOS. We have a super simple interface that allows you to switch between multiple Ethereum accounts

- WalletConnect, which allows for using a DApp in a browser and sign the related transactions in the Tokenary iOS app

Q: What are a few things that excite you in the NFT space right now?

We are incredibly excited about new use-cases like gaming, fantasy sports, digital arts, charity, coupons that NFTs could support and bring to global scale. We hope that many new secondary markets will emerge and drive crypto adoption among the younger generation. It would also be great to buy NFTs through in-app or card purchases.

Fun Stuff

A really good explanation of this abstract idea of “state” from Denis Nazarov of A16Z crypto.

The London Whale, who lost $6.2 billion for JPMorgan Chase & Co.

Charles Howard, the Porta Potty King of NYC.

Wealthy, Successful, and Miserable: why people aren’t happy at work.

A 45 minute documentary on The Black Lotus, the rarest card in Magic: The Gathering. Really interesting deep dive into the world of collectibles, and the quest of how to determine authenticity for said collectibles.

I read this extremely prescient piece from Bill Gates in 1995 when it was compared to Zuckerberg’s new privacy memo by Fred Wilson of USV. Bill Gates is explaining how Microsoft will pivot as a result of the potential of the Internet, and Bill Gates totally nails it. The thing is, this made me think if crypto takes off, how many thought leaders are going to come out and point to their former tweets and blog posts and tell everyone how they called it. They will have been right in this scenario, but, seriously think about that for a second, if crypto takes off there will be literally thousands of tweets and articles about how people called it. Like there are so many tweets.

Much love,

Rahul
