Aave Lending Protocol Reaches Critical State with 100% Utilization Across All Markets

Decentralized lending giant Aave has effectively come to a standstill after all its primary lending markets reached 100% utilization, rendering users unable to withdraw billions of dollars' worth of cryptocurrency. According to DeFi Warhold, this means that approximately $5 billion in stablecoins, including USDT and USDC, are now locked within the protocol, with no available liquidity to facilitate payouts. The crisis unfolded on April 18, following a $292 million exploit of the Kelp DAO rsETH bridge, which led to a bank-run scenario, resulting in a total of $6.6 billion exiting the protocol within a 24-hour period. Aave founder Stani Kulechov declined to comment on the situation, stating he had nothing useful to say. DeFi Warhold emphasized that 100% utilization signifies a complete lack of liquidity, making it impossible to process liquidations and leaving $3 billion in USDT and $2 billion in USDC stuck with no clear exit strategy. Furthermore, the analyst warned that if market prices fluctuate, the bad debt will compound, with no mechanism in place to mitigate it. Natalie Newson, a senior blockchain security researcher at CertiK, concurred that Aave is in a precarious situation, highlighting that 100% utilization not only indicates a lack of liquidity but also means the protocol's self-defense systems are compromised. Newson noted that Aave's woes are a direct result of the KelpDAO exploit, which put the entire DeFi ecosystem to the test, demonstrating the interconnectedness and potential vulnerability of the system. The risk of 100% utilization was anticipated in Aave's risk framework, with former Risk Manager Alex Bertomeu-Gilles having stated in 2020 that at this level, 'no liquidity is left' and the situation becomes 'problematic' for depositors. Technical analyst Duo Nine was the first to identify that Aave had reached 100% utilization, pointing out that the crisis began when the rsETH exploit occurred and AAVE incurred bad debt, prompting large-scale withdrawals from whales such as Justin Sun and MEXC exchange.
