Understanding the Risk of CRV Exposure in the DeFi Ecosystem

Welcome to Finance Redefined, a newsletter designed to provide you with the latest insights and updates on decentralized finance (DeFi). In this edition, we will explore the recent $47 million exploit on Curve Finance and its impact on the DeFi ecosystem.

The exploit on July 30 not only affected Curve Finance but also had a ripple effect throughout the DeFi market. One of the contributing factors was the $100 million loan taken out by the Curve founder, using the platform’s native Curve DAO (CRV) token as collateral. This event led to several lending protocols proposing new governance measures to mitigate the risks associated with CRV exposure. Additionally, the native stablecoin of the ecosystem, crvUSD, experienced depegging due to market conditions on August 3.

Curve Finance Exploit: A Closer Look

The exploit on Curve Finance targeted several stable pools that were using vulnerable versions of the Vyper programming language. The losses incurred from this exploit amounted to over $47 million. The affected contracts were primarily versions 0.2.15, 0.2.16, and 0.3.0 of Vyper. Security firm Ancilia identified 136 contracts using Vyper 0.2.15 with reentrant protection, 98 contracts using Vyper 0.2.16, and 226 contracts using Vyper 0.3.0.

To address the issue, Vyper urged projects relying on these versions to contact them for further assistance.

CEX Price Feed: Preventing a Collapse

As a result of the exploit, the price of CRV collapsed in the DeFi market due to the significant draining of several pools. However, the decentralized exchange price feed saved the token from collapsing to zero. While CRV traded at $0.086 on decentralized exchanges, it maintained a price of $0.60 on centralized exchanges (CEXs).

Curve Finance relies on Chainlink’s oracle system, which incorporates various price feeds, including those from centralized exchanges. The ironic nature of this incident caught the attention of Binance CEO Changpeng Zhao, who acknowledged that it was the CEX price feed that ultimately saved the DeFi protocol.

Founder’s Debt: A Potential Trigger for DeFi Implosion

In addition to the exploit, another concern has arisen regarding loans taken out by the Curve Finance founder, Michael Egorov. These loans are backed by 47% of the circulating supply of CRV, totaling around $100 million. In a report published by crypto research firm Delphi Digital, it was revealed that Egorov holds loans across multiple lending protocols, all backed by 427.5 million CRV. This revelation has sparked speculation about the potential for a massive dump of CRV tokens.

crvUSD Dep pegs Amidst Market Turmoil

The recent exploit had a direct impact on Curve Finance’s native stablecoin, crvUSD. On August 3, it briefly depegged from its value against the United States dollar, experiencing a 0.35% drop before regaining its peg. This reaction was influenced by the uncertain market conditions following the exploit.

To maintain its peg, crvUSD uses a mechanism called PegKeeper, which manages the interest rate and liquidation ratio based on supply and demand dynamics. This ensures that crvUSD retains its value through proper collateralization while balancing the forces of supply and demand.

An Overview of the DeFi Market

Last week, DeFi experienced a bearish trend, with most of the top 100 tokens by market capitalization trading in the red. The total value locked into DeFi protocols remained below $50 billion.

Despite these challenges, the DeFi ecosystem continues to evolve. Stay tuned for future updates, as we bring you the latest stories, insights, and educational content.
