Aave Lending Protocol Hits 100% Utilization, Sparking Widespread Concern

Decentralized lending giant Aave has effectively come to a standstill after its core markets simultaneously 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 within the protocol, which lacks the necessary liquidity to facilitate payouts. The crisis unfolded on April 18, following a $292 million exploit of the Kelp DAO rsETH bridge, where an attacker utilized fake cross-chain messages to mint unbacked rsETH, subsequently using it as collateral to borrow nearly $200 million in WETH on Aave. As news of the 'bad debt' spread, a bank-run scenario emerged, resulting in a total of $6.6 billion exiting the protocol within a 24-hour period. When approached for comment, Aave founder Stani Kulechov stated that he had 'nothing useful to say.' DeFi Warhold emphasized that 100% utilization across all markets signifies a complete lack of liquidity for withdrawals and an inability to process liquidations, leaving $3 billion in USDT and $2 billion in USDC 'stuck with no clean exit.' Furthermore, the analyst warned that if prices fluctuate, the bad debt will compound without any mechanism to cover it, placing the protocol in the worst possible situation. Natalie Newson, a senior blockchain security researcher at CertiK, concurred that Aave is in serious trouble, highlighting that 100% utilization not only indicates a lack of liquidity but also means the protocol's self-defense systems are down. Newson noted that liquidations require liquidity to function and that without it, undercollateralized positions cannot be closed, leading to a situation where bad debt accumulates, and the protocol is unable to recover without external assistance. Aave's risk framework had previously anticipated the possibility of 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, citing the immediate withdrawal of billions by major players like Justin Sun and MEXC exchange following the rsETH exploit. As a result, the ETH market initially hit 100% utilization, soon followed by USDT and USDC pools, leaving these markets 'stuck with money locked.'
