Aave Sees $300 Million Surge in Borrowing Amid Liquidity Crisis Following KelpDAO Exploit

The repercussions of the KelpDAO hack have started to manifest in stablecoin markets, resulting in unforeseen consequences. In the 24 hours following the attack, Aave users borrowed around $300 million against their USDT deposits, according to data from Chaos Labs. This borrowing surge is not driven by demand, but rather by users' inability to withdraw their funds due to maxed-out stablecoin pools. As a result, depositors are taking out loans against their own assets at a loss, simply to access liquidity. This phenomenon can be likened to a bank refusing to process fiat deposit withdrawals, prompting customers to take out loans on these deposits out of desperation. The head of strategy at Spark, a rival DeFi lending platform, noted that the illiquidity in Aave's stablecoin markets has led to a $300 million increase in borrowing with USDT collateral in just one day. To comprehend how the KelpDAO exploit resulted in the simultaneous locking of all stablecoin exits on Aave, it is essential to understand the underlying mechanics of the system and where it failed. Aave is a decentralized finance protocol that enables users to lend and borrow cryptocurrencies without intermediaries. It operates on the assumption that there is always sufficient liquidity for lenders to withdraw their deposits and for borrowers to unwind their positions. However, when this assumption breaks down, the entire system is affected. The KelpDAO exploit involved the manipulation of the protocol's bridge infrastructure, resulting in the release of 116,500 rsETH tokens, worth approximately $292 million. These fake tokens were deposited into lending protocols, primarily Aave, to borrow real assets such as ETH and wETH. The borrowed assets are now gone, and the rsETH tokens holding their place in the vaults are essentially worthless. Aave froze rsETH markets, which stopped the immediate damage but triggered a chain reaction that led to the $300 million borrowing surge. The exploit news prompted whales and large funds to withdraw billions of dollars' worth of cryptocurrencies from Aave's liquidity pools, draining the liquidity and causing utilization rates to reach 100%. This meant that users could no longer withdraw their assets, including USDT and USDC. Trapped depositors, unable to withdraw their money, resorted to borrowing against their locked deposits, accepting significant losses to extract any liquidity from the system. This desperate act of borrowing against their own assets at a loss has reduced liquidity in other markets, with USDC and USDe markets now also at 100% utilization. The incident highlights that decentralized finance does not equate to a risk-free environment.
