DeFi Suffers $13 Billion Loss in Two Days Following KelpDAO Breach

A significant outflow of capital is being witnessed in the decentralized finance ecosystem, triggered by the recent exploit of the KelpDAO protocol over the weekend. A leading DeFi lending platform, Aave, has seen a substantial loss of $8.45 billion in deposits within the past 48 hours, contributing to a broader decline of $13.21 billion in total value locked across DeFi. The total value locked, which represents the combined dollar value of crypto assets deposited across DeFi protocols, is a key metric for measuring liquidity and overall market activity. It has dropped from $99.497 billion to $86.286 billion. Meanwhile, Aave's TVL has decreased by $8.45 billion to $17.947 billion over the same period, according to data from DefiLlama. A closer look at protocol-level data reveals double-digit percentage drops across several platforms, including Euler, Sentora, and Aave, with the losses primarily concentrated in lending, restaking, and yield strategies tied to the affected collateral. The root cause of this decline stems from a $292 million exploit of Kelp's bridge, which allowed attackers to utilize stolen rsETH, a widely used liquid re-staking token in DeFi, as collateral to borrow funds on lending platforms. Since these stolen tokens lacked legitimate collateral backing, borrowing against them created potential shortfalls for lenders, similar to deceiving a traditional bank by depositing fake fiat and taking out loans against it, ultimately leaving the lender with bad debt. In response, protocols have frozen affected markets, while panicked users have withdrawn funds, leading to a broad decline in total value locked. However, token prices have not moved as sharply as deposits, with the AAVE token experiencing a decline of about 2.5% over 24 hours, and UNI and LINK down less than 1% over the same period, according to CoinDesk market data. Peter Chung, head of research at Presto Research, noted that the incident highlights the risks associated with cross-chain infrastructure, particularly in the verification systems used by bridges. Early analysis suggests that the issue may have originated in the verification layer rather than in the smart contracts themselves. Chung also added that the episode demonstrates how interconnected DeFi protocols can transmit shocks beyond the initial point of failure, with withdrawal activity and market freezes extending to platforms without direct exposure to the exploit.
