Recap: DeFi Week of Feb. 17 š¦
| Feb 23, 2020 | 3 |
Hello Defiers, hope youāre enjoying your weekend!
Summing last week up: It was a shorter week for The Defiant because of the U.S. holiday, but an incredibly intense one. Two exploits leveraged flash loans and five different DeFi platforms, including bZX and dYdX, to manipulate the market and make a profit. The schemes, which yielded about $900,000 (depending on the ETH price), had the whole ecosystem scrambling to find which other protocols were vulnerable. It turned out there was a potential exploit on MakerDAO, which triggered an emergency governance vote yesterday. The silver lining is that we got to see decentralized insurance in action as Nexus Mutual paid out bZx lendersā claims. On less stressful news, Decentraland launched, causing digital land sales to spike, and Synthetix is adding ether as collateral.

So This is What a Bank Run on DeFi Looks Like: Three days after bZxās second attack, the protocol is still paused and users are waiting to close out trades and take out their money.
MakerDAO Scrambles to Fix Potential Flash Loan Exploit: All of DeFi is in high alert after the bZx exploits made it clear that hackers can use flash loans to manipulate the system. With MakerDAO holding more than half of all the ETH in decentralized finance, itās a big target, and token movements spurred speculation hackers are preparing an exploit.
Tuesday
Exploits Yield $900k and Raise Questions of āDeā in DeFi: In the last four days, the bZx DeFi trading protocol was exploited twice; the first attack was executed over Valentineās Day and yielded ~1,271 ETH, while the second one was just last night and made ~2,378 ETH. Thatās about $320,000 and $600,000, respectively, with ETH at $250. Questions on whether DeFi is sufficiently decentralized, and on the potential points of failure posed by price oracles, were raised as a result.
