Recap: DeFi Week of April 20 🦄

Hello Defiers, hope you’re having a good weekend!

Summing last week up: dYdX launched the first decentralized perpetual futures contracts, and Futureswap launched shortly after with similar assets, attracting so much attention it had to warn users its software hadn’t been audited. Speaking of untested software, Hegic is another exciting project that launched this week, releasing a decentralized options market, but its developers found a bug in the code with the potential of locking up users’ funds. Coinbase released price oracles for DeFi apps, Zerion built an SDK to connect DeFi protocols, and PoolTogether now allows users to link their lottery tickets and increase their chance of winning.

Analyst Andrew Kang wrote about the different Bitcoin-to-Ethereum efforts, Covalent’s Ganesh Swami crunched numbers to find how Ethereum tokens’ market caps have grown over time, and @DeFi_Dad’s tutorial this week explains how to get paid (or pay for) Zoom calls with ETH and 2Key Network. Aave engineer Emilio Frangella breaks down DeFi’s biggest hack yet, and MEW founder Kosala Hemachandra in this week’s exclusive interview and podcast says volume is surging amid the coronavirus pandemic.

Interview

"Volumes Have Almost Tripled; Crypto Was Made for This," MEW's Kosala Hemachandra Says

This week’s interview is with MyEtherWallet founder and CEO Kosala Hemachandra. As the head of one of the most popular Ethereum interfaces, Kosala has a unique perspective on how the global pandemic has impacted activity. He also talks about how crypto was built for crises, about the importance of building a decentralized product —if it’s custodial, it’s not worth it— and what he believes the future of digital wallets will look like. Lastly, he told me about MEW’s next big project: a DEX.

🎙Listen to the interview first hand on this week’s podcast.

Op-Eds

The Cross-Chain Pegging Dilemma

Builders are creating Bitcoin-backed Ethereum tokens and concocting “bridges” connecting the two chains in so many different projects that it’s hard to keep track. Andrew Kang, a venture investor and analyst deep in the crypto space, has compiled these efforts in a Bitcoin-to-DeFi primer. You’ll get the pros and cons of Bitcoin tokens and bridges including by Ren, Synthetix, Keep, pTokens, and TokenIon. And see where the fall in the decentralization and scalability scale.

Ethereum is a True Platform for Fintech Innovation

Ethereum’s market capitalization has been sliding sideways for the last couple of years at around 20 billion dollars. That’s a grim picture, but in reality, innovation on Ethereum is at all time high. Bill Gates once said, “A platform is when the economic value of everybody that uses it exceeds the value of the company that creates it.” Ethereum is starting to prove itself as a platform for fintech innovation as the market cap of tokens built on top of it grows, Covalent cofounder Ganesh Swami writes.
