TLDR
DeFi United is a multi?protocol rescue fund created around Aave to plug a huge rsETH-related hole of up to roughly 100,000 ETH from the KelpDAO exploit.
- The fund was launched after a KelpDAO rsETH bridge hack left Aave with up to $230 million in bad debt and an rsETH shortfall modeled at 68,900 to over 100,000 ETH.
- Confirmed commitments sit around $160 million (roughly 69,000 ETH), with large pledges from Mantle, Aave DAO, Ether.fi, Lido, Golem and Aave founder Stani Kulechov, while some reports count over 100,000 ETH in total support.
- The effort shows DeFi can organize its own bailouts, but it also raises moral hazard questions and will likely drive stricter risk rules for bridges, restaking tokens and collateral.
Deep Dive
1. Why DeFi United Exists
On 18 April 2026, attackers exploited KelpDAOs LayerZero-based rsETH bridge, minting 116,500 unbacked rsETH and using it as collateral on Aave V3 to borrow about $191 million in assets, leaving large bad debt on Aave markets. Detailed incident reports estimate Aaves loss range at $123.7 million to $230.1 million, depending on how the deficit is socialized across rsETH holders and networks.
In response, Aave service providers and partner protocols launched DeFi United, a relief vehicle focused on restoring rsETH collateralization and clearing the bad debt, rather than trying to claw back already-laundered funds. Coverage targets the modeled shortfall of roughly 68,900 to more than 100,000 ETH, according to a comprehensive recap of the DeFi United fund.
2. How Much Has Been Raised And By Whom
By late April, DeFi United had secured around $160 million in firm commitments, including 55,000 ETH from Mantle and Aave DAO combined, plus major contributions from Ether.fi, Lido DAO, Golem Foundation and others, as reported in the same funding update. Aave founder Stani Kulechov pledged 5,000 ETH of personal funds, and multiple teams contributed additional thousands of ETH or stETH.
Earlier coverage from The Defiant noted that the rsETH deficit itself exceeds 100,000 ETH and warned EarnETH vault users could face up to 9,000 ETH in losses without full coverage, framing the scale of the rsETH shortfall. A broader regulatory wrap-up at Tokenpost describes DeFi United as having raised over 100,000 ETH when counting the total relief stack, including frozen attacker funds on Arbitrum and pending governance contributions that are still being formalized.
Confidence: moderate because firm pledged ETH is well documented, while the over 100,000 ETH label depends on how you count frozen and still?voting support.
3. Why This Matters For DeFi Users
The KelpDAO exploit and DeFi United response erased more than $10 billion in DeFi TVL and highlighted the systemic risk of accepting bridge-minted restaking tokens as high-grade collateral, as summarized in a coordinated recovery overview.
This fund is one of the clearest examples of a protocol-led backstop, where DAOs and major protocols voluntarily recapitalize a troubled market to prevent wider contagion. That can restore confidence, but it may also encourage riskier behavior if participants assume future bailouts.
Watch whether rsETH is fully re?backed, how Aave adjusts collateral and LTV rules for bridged and restaked assets, and whether similar cross?protocol safety nets become a norm after major exploits.
Conclusion
DeFi United shows that leading DeFi protocols can mobilize large, coordinated capital pools to contain a systemic shock on Aave and rsETH, with pledged and managed resources approaching the 100,000 ETH scale of the modeled shortfall. The longer?term story is whether this episode pushes the ecosystem toward stricter bridge and collateral standards, or instead normalizes informal bailouts as a recurring part of DeFis risk cycle.
