Decentralized lending giant Aave has effectively halted operations after its primary lending protocols depleted their available funds, rendering users unable to withdraw billions of dollars in cryptocurrency. According to DeFi Warhold, the 100% utilization of Aave's markets signifies a critical lack of liquidity, preventing the protocol from processing withdrawals or liquidations. Approximately $5 billion in stablecoins, including USDT and USDC, are currently locked due to the liquidity crisis.
The situation began to unfold on April 18, following a $292 million exploit of the Kelp DAO rsETH bridge, which led to a massive exodus of $6.6 billion from the protocol within a 24-hour period. Aave founder Stani Kulechov declined to comment on the crisis, stating he had nothing useful to say. DeFi Warhold emphasized that the 100% utilization across all markets is equivalent to a complete halt, with no available liquidity for withdrawals, and liquidations unable to be processed, resulting in $3 billion in USDT and $2 billion in USDC being stuck without a clear exit strategy.
The situation is further complicated 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 the 100% utilization not only indicates a lack of liquidity but also signifies that the protocol's self-defense systems are down. Newson explained that liquidations require liquidity to function, and without it, undercollateralized positions cannot be closed, leading to a perpetual accumulation of bad debt, which could ultimately render the protocol irrecoverable without external assistance. The researcher noted that Aave's issues stem from the fallout of the KelpDAO exploit, which has put the entire DeFi system to the test.
Aave's risk framework had previously anticipated the possibility of 100% utilization, with former risk manager Alex Bertomeu-Gilles warning in 2020 that at this level, no liquidity would be left, and the situation would become problematic for depositors seeking to withdraw their funds. Technical analyst Duo Nine was the first to highlight Aave's 100% utilization, pointing out that the situation began with the rsETH exploit, which led to bad debt and prompted major players like Justin Sun and MEXC exchange to withdraw billions from the protocol, ultimately causing the USDT and USDC pools to also reach 100% utilization and become stuck with locked funds.
