Aave DAO Weighs 25,000 ETH Injection to Plug rsETH Exploit Backing Gap
Aave service providers have submitted a governance proposal asking the Aave DAO to commit 25,000 ETH to the DeFi United recovery initiative, aiming to help cover a remaining collateral shortfall tied to the rsETH exploit on April 18, 2026.
The attack stemmed from a compromised LayerZero bridge, which enabled the minting of unbacked rsETH. The attacker subsequently borrowed assets on Aave, leaving the protocol with bad debt. Aave said the exploit released 152,577 rsETH from the LayerZero lockbox, translating at prevailing ratios into an initial backing deficit of about 163,183 ETH.
Mitigation efforts have already reduced the gap. KelpDAO froze 40,373 rsETH, equivalent to about 43,168 ETH, and the Arbitrum Security Council froze 30,766 ETH linked to the attacker. Additional recoveries may come via liquidations: Aave positions could return up to 12,323 WETH, and Compound positions another 1,845 WETH. Together, these sources account for roughly 54% of the original shortfall.
As recovery funding builds, ecosystem participants have lined up support. Ether.fi and Lido DAO have floated contributions of up to 5,000 ETH and 2,500 ETH. Aave executives also pledged funds, with Emilio Frangella committing 500 ETH and founder Stani Kulechov 5,000 ETH. Mantle proposed a credit facility of up to 30,000 ETH. With additional support from Golem, BGD Labs and users, total contributions were estimated at about 69,534 ETH. X user DCF GOD said combined contributions and frozen funds, including roughly 30,700 ETH frozen on Arbitrum, could fully cover the deficit if approved.
Under the proposal, Aave's contribution is fixed at 25,000 ETH. Additional donations would be used to repay Mantle's credit line rather than reduce the DAO's commitment, a structure intended to limit longer-term exposure to external borrowing. Execution remains contingent on external steps, including Kelp reopening withdrawals and LayerZero restoring the bridge, and timelines could extend for weeks as funds become liquid.
Separately, JPMorgan analysts said recurring exploits continue to weigh on institutional sentiment, adding that users have increasingly rotated into stablecoins after such incidents.
