Decentralized lending platform Aave has effectively halted operations after all its primary lending protocols exhausted their available funds, resulting in users being unable to withdraw billions of dollars' worth of cryptocurrency. According to DeFi Warhold, this 100% utilization signifies a critical lack of liquidity, rendering the protocol incapable of processing withdrawals or liquidations. Approximately $5 billion in stablecoins, including USDT and USDC, are currently locked, with the protocol lacking the necessary liquidity to facilitate their payout. The crisis unfolded on April 18, following a $292 million exploit of the Kelp DAO rsETH bridge, which led to a 'bad debt' situation.
As news spread, a bank-run scenario emerged, culminating in $6.6 billion exiting the protocol within 24 hours. Aave founder Stani Kulechov declined to comment, stating he had 'nothing useful to say.' DeFi Warhold emphasized that 100% utilization across all markets simultaneously is equivalent to a complete halt, with no available liquidity for withdrawals, and liquidations unable to be processed. This leaves $3 billion in USDT and $2 billion in USDC 'stuck with no clean exit.' The situation is further exacerbated by the potential for bad debt to compound if prices fluctuate, with no mechanism in place to mitigate it.
Natalie Newson, a senior blockchain security researcher at CertiK, warned that Aave is in severe trouble, as 100% utilization not only indicates a lack of liquidity but also signifies that the protocol's self-defense systems are compromised. Newson highlighted that liquidations require liquidity to function, and without it, undercollateralized positions cannot be closed, leading to an accumulation of bad debt that the protocol may not be able to recover from without external assistance. The KelpDAO exploit has put the entire DeFi system to the test, demonstrating the interconnectedness that makes DeFi powerful but also vulnerable to large-scale disasters. Aave's risk framework had anticipated the possibility of 100% utilization, with former Aave Risk Manager Alex Bertomeu-Gilles previously stating that at this level, 'no liquidity is left' and the situation becomes 'problematic' for depositors.
Technical analyst Duo Nine was the first to point out that Aave had reached 100% utilization, noting that the rsETH exploit and subsequent bad debt led to whales withdrawing billions from AAVE, causing the ETH market to hit 100% utilization and spreading to USDT and USDC pools.
