Aave's Lending Protocols Reach Maximum Capacity, Sparking Concerns

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' worth of cryptocurrency. According to DeFi Warhold, this means that approximately $5 billion in stablecoins, including USDT and USDC, are now locked, with the protocol lacking the necessary liquidity to facilitate payouts. The crisis unfolded on April 18, following a $292 million exploit of the Kelp DAO rsETH bridge, which led to a 'bad debt' of nearly $200 million in WETH. As news of the exploit spread, a bank-run scenario ensued, 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 explained that 100% utilization across all markets signifies a complete lack of liquidity, preventing liquidations from being processed and leaving $3 billion in USDT and $2 billion in USDC 'stuck with no clean exit.' Furthermore, the analyst warned that if market prices fluctuate, the bad debt will compound, with no mechanism in place to mitigate it. This, according to Warhold, is the worst possible scenario for a lending protocol, as it leaves the platform vulnerable to further bad debt with no means of self-protection. Natalie Newson, a senior blockchain security researcher at CertiK, concurred that Aave is in serious trouble, emphasizing that 100% utilization not only indicates a lack of liquidity but also means that the protocol's defense mechanisms are incapacitated. Newson noted that liquidations require liquidity to function, and without it, undercollateralized positions cannot be closed, leading to a perpetual accumulation of bad debt. This, she warned, will render the protocol unable to recover without external assistance. Aave's risk framework had, in fact, anticipated the possibility of 100% utilization, with former Risk Manager Alex Bertomeu-Gilles having stated in 2020 that at this level, 'no liquidity is left,' and the situation becomes 'problematic' for depositors seeking to withdraw their funds. Technical analyst Duo Nine was the first to highlight that Aave had reached 100% utilization, pointing out that the crisis began when the rsETH exploit occurred, resulting in bad debt and prompting whales like Justin Sun and MEXC exchange to withdraw billions from Aave.
