Decentralized lending platform Aave has effectively come to a standstill after all its core markets reached 100% utilization, rendering users unable to withdraw billions of dollars in cryptocurrency. According to DeFi Warhold, this situation means that approximately $5 billion in stablecoins, including USDT and USDC, are now inaccessible due to a lack of liquidity. The crisis unfolded on April 18, following a $292 million exploit of the Kelp DAO rsETH bridge, which led to a 'bad debt' of nearly $200 million in WETH. As the news spread, a massive withdrawal of $6.6 billion from the protocol occurred within 24 hours, triggering a bank-run-like scenario.
Aave founder Stani Kulechov stated that he had no useful comments on the matter. DeFi Warhold explained that 100% utilization signifies a complete lack of liquidity, preventing liquidations from being processed and leaving $3 billion in USDT and $2 billion in USDC 'stuck with no clean exit.' Furthermore, analyst DeFi Warhol warned that if prices fluctuate, the bad debt will compound, with no mechanism in place to cover it, putting the protocol in an extremely vulnerable position. Natalie Newson, a senior blockchain security researcher at CertiK, concurred that Aave is in a critical situation, emphasizing that 100% utilization not only indicates a lack of liquidity but also means the protocol's self-defense systems are down.
Newson cautioned that the interconnectivity of DeFi, while powerful, can also turn a single point of failure into a large-scale disaster. Aave's risk framework had anticipated this scenario, with former Risk Manager Alex Bertomeu-Gilles noting in 2020 that at 100% utilization, 'no liquidity is left' and the situation becomes 'problematic' for depositors. Technical analyst Duo Nine highlighted that Aave had reached 100% utilization, triggering a chain reaction that spread to USDT and USDC pools, resulting in over $6 billion in assets being withdrawn from the protocol within hours.
