Decentralized lending giant 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 means that roughly $5 billion in stablecoins, including USDT and USDC, are now locked, with the protocol lacking the necessary liquidity to facilitate payouts.
The crisis began on April 18, following a $292 million exploit of the Kelp DAO rsETH bridge, which led to a classic bank-run scenario, resulting in $6.6 billion exiting the protocol within 24 hours. Aave founder Stani Kulechov declined to comment on the situation, stating he had nothing useful to say. Analysts warn that the platform's 100% utilization across all markets is equivalent to a complete halt, with no liquidity available for withdrawals and liquidations unable to be processed.
This has left $3 billion in USDT and $2 billion in USDC stuck with no clear exit strategy. The situation is further complicated by the fact that if prices fluctuate, bad debt will compound, with no mechanism in place to mitigate it.
Natalie Newson, a senior blockchain security researcher at CertiK, emphasized that Aave is in serious trouble, with the protocol's self-defense systems down due to the lack of liquidity. Newson noted that liquidations require liquidity to function, and without it, undercollateralized positions cannot be closed, leading to a buildup of bad debt that the protocol may not be able to recover from without external assistance.
The incident highlights the interconnected nature of DeFi, where a single point of failure can have far-reaching consequences. Aave's risk framework had anticipated the possibility of 100% utilization, but the current situation has still caught the platform off guard. Technical analyst Duo Nine was the first to highlight Aave's 100% utilization, noting that the crisis began when the rsETH exploit led to bad debt, prompting large-scale withdrawals from the platform.
