According to monetsupply.eth, Spark’s Strategy Lead, in a post on X, Spark has long maintained a relatively high borrowing interest rate cap for its SparkLend ETH market. Although this policy caused many users to migrate to Aave—resulting in substantial loss of business and revenue—the current market liquidity crisis has validated the prudence of this strategy. Presently, Aave is experiencing severe liquidity shortages across multiple chains—including Ethereum Mainnet, Arbitrum, Polygon Plasma, Mantle, and Base—with ETH borrowing utilization reaching 100%. This has prevented depositors from withdrawing funds and hindered normal liquidation of ETH collateral. He warns that if the current liquidity crunch persists, a 15–20% drop in ETH’s price could expose Aave to widespread bad debt—compounded by the potential impact of the rsETH vulnerability incident.
Odaily News: A LayerZero cross-chain bridge related to Kelp DAO was hacked on Saturday, resulting in 116,500 rsETH worth $291 million flowing to a new wallet. The hacker used the illicitly obtained rsETH as collateral to borrow on Aave, causing the utilization rate of Aave's core lending pool to reach 100% and triggering a liquidity crunch. According to monitoring by 0xngmi, as of early Sunday, the net withdrawal amount from Aave had reached $6.2 billion. Kelp DAO has suspended the rsETH contracts on the Ethereum mainnet and several L2 networks. Affected by this, the price of the Aave token fell 16% to $90.13, and the price of Ethereum dropped 2% to $2,300. Currently, Justin Sun has posted on platform X attempting to negotiate with the hacker.
Odaily News, Spark's strategy lead monetsupply.eth posted on X, stating that as the stablecoin market begins to face a liquidity shortage, the situation is entering a more dangerous phase, in my opinion. Approximately 16.5% of the ETH market is backed by rsETH. If losses on rsETH-backed loans are shared across the mainnet and external chains, they could face a 10% to 15% cut in emode, with the remaining 2% to 3% cut left for ETH suppliers to flatten the umbrella structure. ETH suppliers naturally tend to exit as soon as possible to avoid this risk, so utilization is locked at 100%, and the borrowing rate is insufficient to incentivize the repayment of unrelated LST loops (wstETH, weETH) to release liquidity. Since ETH cannot be withdrawn, users who borrowed stablecoins like USDT using ETH as collateral cannot close their positions even when stablecoin borrowing rates rise, which cuts off the typical incentive mechanisms that maintain market health. Currently, there are two unhealthy incentives causing market utilization to be locked at 100%:1) ETH holders cannot close positions to maintain a healthy LTV, and liquidators cannot atomically withdraw or sell collateral. A drop in the ETHUSD price could lead to bad debt.2) Users supplying USDT, in order to exit their holdings, tend to maximize borrowing of other stablecoins. This position is currently generating positive yield (temporarily), so the exit cost is low; if conditions worsen, they can recover at least 75% of the position's value.The bottom line is that for these pooled/restaking lending markets to function properly, liquidity must be maintained at all costs. The recent weakening of the slope2 for Aave's maximum borrowing rate is having a negative impact and significantly increasing the risk of cascading market failure.
Monetsupply.eth, Strategy Lead of Spark Protocol, posted on X stating that in January this year, low-utilization assets such as rsETH were delisted, and the scope of acceptable collateral and protocol functionalities has been continuously tightened. At the time, this move triggered strong backlash from users employing “ETH circular leverage” strategies. Additionally, Spark has long imposed relatively high maximum interest rate caps on its ETH lending market. Over the past year, Spark has ceded part of its business and revenue to Aave—whose ETH borrowing rates at one point dropped to 10% or lower. However, amid the current market crisis, this strategy has proven more prudent: SparkLend still maintains ample ETH withdrawal liquidity, whereas Aave is experiencing liquidity strain—or even “locking”—across Ethereum mainnet and multiple Layer-2 chains including Arbitrum and Base. Monetsupply.eth further warned that, since ETH serves as the core collateral asset, when market utilization reaches 100%, liquidations of collateral will fail to execute normally. Liquidity exhaustion not only degrades depositors’ experience but may also pose systemic risk. Given Aave’s current liquidity shortage, a 15–20% drop in ETH’s price could trigger significant bad debt accumulation—exacerbated by potential fallout from the rsETH incident.
Odaily News: Sonic Labs co-founder and Flying Tulip founder Andre Cronje posted on platform X, stating that his team is continuing to investigate the L0/rsETH incident. Preliminary reports indicate that approximately $200 million worth of rsETH was stolen, possibly due to a private key leak or configuration error. The related assets were subsequently deposited into Aave as collateral to borrow ETH (due to insufficient rsETH liquidity).Andre Cronje pointed out that the affected positions are technically still overcollateralized. However, if bad debt occurs, Aave's token mechanism and Safety Module will serve as the first line of defense to absorb the risk. Nevertheless, Aave has no mechanism to subsidize user losses, as doing so could trigger a bank run. Currently, Aave holds approximately $7 billion in ETH with an outstanding borrowing amount of around $100 million, so the overall impact of this incident is limited. Furthermore, prioritizing user liquidity, Flying Tulip has withdrawn all its ETH from Aave to its fund management wrapper contract. This action was taken because Aave's available liquidity had fallen below its set minimum threshold.
According to Cointelegraph, Fireblocks, an enterprise-grade digital asset infrastructure platform, has launched a new feature called Earn, enabling institutional clients to allocate stablecoin balances into on-chain lending strategies supported by Aave and Morpho to improve the efficiency of idle capital utilization. The product’s initial integrations include the Morpho vaults curated by Sentora and the Aave stablecoin lending markets, and it is now available to Fireblocks customers via Early Access. Fireblocks notes that yields are generated by the underlying protocols and are variable—not guaranteed—and may be zero. Data shows that Aave and Morpho are currently the two largest decentralized lending protocols by total value locked (TVL).
Odaily News Aave posted on the X platform stating that it has taken note of the attack on the CowSwap frontend, but this incident has not affected the security of the Aave interface or the underlying protocol. As a precautionary measure, the CowSwap team has temporarily disabled the swap endpoints for integrators. Within the Aave interface, transactions have been switched to the ParaSwap routing where available to ensure continuity of user transactions.
