Aave Decentralized Lending Platform Hits Crisis Point with 100% Utilization

Aave, a leading decentralized lending platform, has effectively come to a standstill after all its core markets reached maximum utilization, rendering users unable to withdraw billions of dollars in cryptocurrency. DeFi Warhold explained that this means there is no available liquidity to facilitate withdrawals, and liquidations cannot be processed. Approximately $5 billion in stablecoins, including USDT and USDC, are currently locked within the protocol, which lacks the necessary liquidity to payout these assets. The crisis began on April 18 following a $292 million exploit of the Kelp DAO rsETH bridge, where an attacker used forged cross-chain messages to mint unbacked rsETH, depositing it into Aave as collateral to borrow nearly $200 million in WETH. This led to a bank-run scenario, with $6.6 billion exiting the protocol in under 24 hours. Aave founder Stani Kulechov stated he had no useful comment on the situation. DeFi Warhol noted that 100% utilization across all markets is equivalent to a full stop, meaning no liquidity is available for withdrawals, and liquidations cannot be executed, resulting in $3 billion in USDT and $2 billion in USDC being stuck with no clear exit. Furthermore, if prices fluctuate, bad debt compounds without a mechanism to cover it, placing the protocol in a precarious situation where it cannot protect itself against further bad debt. Natalie Newson, a senior blockchain security researcher at CertiK, emphasized that Aave is in serious trouble, as 100% utilization not only signifies a lack of liquidity but also indicates that the protocol's self-defense systems are down. Liquidations require liquidity to function; without it, undercollateralized positions cannot be closed, and bad debt accumulates, leaving the protocol unable to recover without external assistance. Newson highlighted that Aave's situation is a concern for the entire DeFi system, as the interconnectivity that makes DeFi powerful can also turn a single point of failure into a large-scale disaster. Aave's risk framework had anticipated 100% utilization, with former Aave Risk Manager Alex Bertomeu-Gilles stating in 2020 that at this level, no liquidity is left, and the situation becomes problematic, as depositors are unable to withdraw their funds. Technical analyst Duo Nine was the first to point out that Aave had reached 100% utilization, noting that when the rsETH exploit occurred and AAVE incurred bad debt, large investors like Justin Sun and MEXC exchange immediately withdrew billions from AAVE, initially causing the ETH market to hit 100% utilization.
