TLDR
A group of leading DeFi protocols has formed a DeFi United recovery fund that has already raised more than 100,000 ETH to repair the rsETH/KelpDAO exploit fallout.
- Aave (AAVE) and partners have raised over 100,000 ETH for DeFi United, with a separate bid to unlock 30,765 frozen ETH from Arbitrums DAO for the same effort.
- The fund targets a major rsETH collateral shortfall after a KelpDAO bridge bug enabled a roughly $292 million exploit and left Aave with around $196 million in bad debt.
- Recovery hinges on DAO governance timelines and on how losses are allocated among DAOs, treasuries and token holders rather than ordinary users.
Deep Dive
1. Who Is In The DeFi Coalition
Aave founder Stani Kulechov launched the DeFi United initiative and opened the defiunited.eth address to crowdsource a recovery pool for rsETH. Aave says the fundraiser has collected more than 100,000 ETH (over $230 million) from over 85,000 addresses, with support from major protocols such as Lido, EtherFi, Mantle and others, according to a broad market recap that highlights DeFi United raising over 100,000 ETH.
Separately, Aave Labs, KelpDAO, LayerZero, EtherFi and Compound have filed a Constitutional AIP on Arbitrum asking its DAO to release 30,765.67 ETH that the Arbitrum Security Council froze after tracing it to the exploiter, with the funds earmarked for DeFi United via a 2-of-3 Gnosis Safe controlled by Aave, KelpDAO and Certora under that proposal.
2. How Big The Hole Is
The crisis started when a KelpDAO rsETH Unichain to Ethereum bridge bug released 116,500 rsETH on Ethereum without burning the corresponding tokens on the source chain, breaking the bridges backing invariant and creating a large deficit for rsETH holders and lenders on Aave. Estimates put the exploit at about $292 million, with roughly $196 million in bad debt sitting on Aave after the attacker used the unbacked rsETH as collateral to borrow real assets, as summarized in a market note on the KelpDAO hack and DeFi United raising 43,500 ETH.
Aaves own breakdown shows the rsETH deficit was initially around 163,183 ETH and has been reduced to about 75,081 ETH through layered loss absorption and ecosystem pledges, including an Umbrella module that takes first losses, ecosystem contributions of roughly 14,570 ETH, an Aave DAO proposal for 25,000 ETH, and a 30,000 ETH facility from Mantle, according to an Aave-focused analysis.
3. User Impact And What To Watch
For Aave and rsETH users, the goal of DeFi United and the related DAO proposals is to restore rsETH backing to 100 percent so that ordinary depositors and borrowers are made whole and the bad debt is absorbed at the protocol and ecosystem level.
However, the Arbitrum AIP runs through a constitutional process that can take around 49 days from forum discussion through onchain execution, and Aaves own 25,000 ETH allocation must also clear governance, meaning recovery speed is constrained by DAO timelines rather than just technical readiness, as outlined in the detailed Arbitrum proposal process for freeing the frozen ETH.
If the coalition secures the Arbitrum funds and executes its multi layer plan, most losses are likely to be socialized across DAOs and treasuries, but delays or failed votes could extend uncertainty for rsETH and Aave users.
Conclusion
The 100k plus ETH DeFi United fund shows that large DeFi protocols can coordinate rapid, cross ecosystem responses when a restaking exploit threatens core lending markets. The ultimate impact will depend on whether Arbitrum and Aave governance approve the proposed allocations in time to fully recapitalize rsETH, which will determine how much risk remains for everyday users versus protocol treasuries and token holders.
