The decentralized finance sector is facing one of its biggest stress tests of 2026 after a major exploit involving KelpDAO’s rsETH token sent shockwaves through Aave and the wider crypto lending market. In response, Aave and several leading DeFi protocols have moved quickly to coordinate a recovery effort now known as “DeFi United,” with commitments surpassing 43,500 ETH, worth more than $101 million at current market prices.
The rescue campaign follows an April 18 exploit tied to KelpDAO’s LayerZero-powered rsETH bridge. According to Aave’s own incident disclosures, the issue did not originate from Aave’s smart contracts. Instead, the problem was connected to rsETH, a liquid restaking token that was used as collateral across Aave markets.
Aave Freezes Affected rsETH Markets
Aave said its pools remained operational and that the incident was scoped to the affected asset rather than a vulnerability in the Aave protocol itself.
The impact was immediate. Aave’s Guardian froze rsETH and wrsETH markets across multiple deployments, including Ethereum, Arbitrum, Base, Mantle, Linea and other supported networks. Freezing the markets blocked new deposits and new borrowing against the affected collateral, while existing positions remained subject to normal repayment and liquidation rules.
How the KelpDAO Exploit Affected Aave Liquidity
The core problem was that unbacked or underbacked rsETH entered the DeFi lending system and was used to borrow wrapped Ether, or WETH. Aave’s April 20 incident report showed large exposures across affected markets, with total borrowed amounts continuing to change as interest accrued.
The report also stressed that the final shortfall depended on unresolved factors, including recovery, recapitalization, redemption pricing and how KelpDAO would allocate losses.
As fear spread, WETH liquidity on Aave tightened sharply. Users rushed to exit, and utilization in some ETH lending markets rose to 100%, meaning lenders could not withdraw normally because nearly all supplied ETH had been borrowed.
DeFi United Recovery Effort Gains Momentum
The DeFi United initiative is an attempt to prevent that liquidity crunch from turning into a deeper confidence crisis. Reported commitments include Mantle proposing up to 30,000 ETH, the EtherFi Foundation proposing 5,000 ETH, and the Golem Foundation together with Golem Factory offering 1,000 ETH.
Lido DAO has also proposed a capped contribution of up to 2,500 stETH to a dedicated relief vehicle, while other ecosystem participants have signaled support.
Aave founder Stani Kulechov has also personally pledged 5,000 ETH, according to reports on the recovery effort. The goal is not simply to patch one protocol’s balance sheet. The broader aim is to restore confidence in rsETH backing, reduce potential Aave bad debt, and show that decentralized finance can organize quickly when a shared risk threatens multiple platforms.
Emergency Redemption Tools Help Aave Users Exit
The response has also included market-level workarounds for users stuck in frozen liquidity. Fluid, working with Lido, Ether.fi, 1inch, 0x and Kyber, launched an aWETH Redemption Protocol to help Aave ETH lenders and loopers exit or rebalance positions.
The system processed 58,510 aWETH, worth about $136 million, in its first 48 hours, according to reporting based on Fluid’s public dashboard.
That mechanism matters because it gives users an alternative path when direct withdrawals are unavailable. Instead of waiting for WETH liquidity to normalize, lenders can swap aWETH into assets such as wstETH or weETH, accepting a smaller haircut than the steep discounts seen in panic-driven secondary markets.
Liquid Restaking Tokens Face New Scrutiny
Still, the crisis has exposed a hard truth about decentralized finance. Liquid restaking tokens, cross-chain bridges and lending protocols are deeply interconnected. When one asset loses reliable backing, the damage can move through collateral markets, borrowing pools and liquidity venues within hours.
Aave’s report made clear that there was no single final outcome yet, because recovery decisions and loss allocation remained outside Aave’s direct control.
For Aave users, the most important point is that the protocol’s core smart contracts were not reported as compromised. Aave’s risk controls reacted by freezing affected assets, adjusting interest rates and limiting further exposure.
What the Aave Recovery Means for DeFi
For the wider Ethereum DeFi ecosystem, the recovery effort could become a defining moment. If DeFi United succeeds, it may strengthen the case that decentralized protocols can coordinate without centralized bailouts. If it falls short, the market may demand stricter collateral standards, tougher bridge security requirements and more conservative risk parameters for liquid restaking tokens.
The coming days will be crucial. Governance proposals still need approvals, pledged ETH must be converted into effective relief, and users will be watching whether Aave liquidity improves without creating new risks elsewhere.
What is already clear is that the KelpDAO rsETH exploit has become more than a single hack. It is now a major test of DeFi risk management, Ethereum lending resilience and the ability of decentralized communities to act together under pressure.
