Kelp DAO Hack Triggers DeFi United Response: Aave and Partners Rally to Restore rsETH Stability

In a swift and coordinated move, Aave (AAVE) and several major decentralized finance (DeFi) partners have launched ‘DeFi United’ to address the aftermath of the Kelp DAO hack. This joint initiative aims to restore stability to rsETH, a liquid restaking token severely impacted by the exploit. The attack, which involved an attacker minting uncollateralized rsETH and borrowing approximately $190 million, triggered a mass withdrawal event and sent shockwaves through the DeFi ecosystem.

Aave and DeFi Partners Unite After Kelp DAO Hack

The Kelp DAO hack, reported on June 24, 2025, exploited a vulnerability in the protocol’s smart contracts. The attacker minted uncollateralized rsETH and used it as collateral on Aave to borrow significant assets. This action caused a rapid depegging of rsETH and prompted a cascade of withdrawals. In response, Aave founder Stani Kulechov proposed a coordinated relief effort, quickly gaining support from Lido Finance and Ether.fi.

According to a report from CoinDesk, the ‘DeFi United’ initiative focuses on stabilizing the system rather than recovering the stolen funds. Lido Finance has proposed allocating up to 2,500 stETH, valued at approximately $5.7 million, to a dedicated relief fund. Additionally, Ether.fi and Stani Kulechov have each proposed contributing 5,000 ETH to the fund. These contributions aim to provide liquidity and restore confidence in rsETH.

Understanding the Kelp DAO Hack and Its Impact

The hack exploited a flaw in Kelp DAO’s minting mechanism, allowing the attacker to create rsETH without proper collateral. The attacker then deposited this rsETH on Aave, borrowing nearly $190 million in various cryptocurrencies. This event triggered a mass withdrawal from rsETH pools, causing its price to plummet and creating a liquidity crisis.

The impact of the hack was immediate and severe. The total value locked (TVL) in Kelp DAO dropped sharply, and rsETH traded at a significant discount to its underlying assets. This event highlighted the risks associated with liquid restaking tokens and the interconnected nature of DeFi protocols.

Lido Finance Proposes stETH Relief Fund

Lido Finance, the largest liquid staking protocol, stepped in to support the recovery effort. The proposal to allocate up to 2,500 stETH to the relief fund is a significant commitment. StETH, a liquid staking token for Ethereum, is widely used as collateral across DeFi. By contributing stETH, Lido aims to provide a stable asset that can be used to backstop the rsETH market.

The Lido relief fund is designed to be deployed strategically. It will provide liquidity to rsETH trading pairs and help restore the token’s peg. This move demonstrates the collaborative spirit within the DeFi community and the importance of protocol-level support during crises.

Ether.fi and Aave Founder Contribute 5,000 ETH Each

Ether.fi, a liquid restaking protocol, and Aave founder Stani Kulechov have each committed 5,000 ETH to the relief fund. This brings the total proposed contributions to approximately 12,500 ETH, worth over $28 million at current prices. These funds will be used to buy back rsETH and provide liquidity on decentralized exchanges.

The contributions from Ether.fi and Kulechov underscore the personal and professional stakes involved. Kulechov, as the founder of Aave, has a direct interest in maintaining the stability of the protocol. Ether.fi, as a competitor in the liquid restaking space, also benefits from a stable ecosystem.

How DeFi United Aims to Stabilize rsETH

The ‘DeFi United’ initiative has outlined a multi-pronged strategy to stabilize rsETH. First, the relief fund will be used to provide liquidity on decentralized exchanges, allowing users to trade rsETH at fair prices. Second, the fund will support buybacks of rsETH to reduce the circulating supply and push the price back toward its peg. Third, the initiative will work with Aave to adjust risk parameters for rsETH, reducing the likelihood of future exploits.

This coordinated approach is essential for restoring trust in the DeFi ecosystem. The hack exposed vulnerabilities in the liquid restaking model, but the rapid response from major protocols shows the resilience of the space.

Timeline of Events: From Hack to Response

• June 24, 2025: Kelp DAO hack occurs. Attacker mints uncollateralized rsETH and borrows $190 million on Aave.
• June 24, 2025: rsETH price depegs. Mass withdrawals begin.
• June 25, 2025: Aave founder Stani Kulechov proposes ‘DeFi United’ initiative.
• June 26, 2025: Lido Finance proposes allocating 2,500 stETH to relief fund.
• June 27, 2025: Ether.fi and Kulechov each propose contributing 5,000 ETH.
• June 28, 2025: Relief fund begins operations. rsETH price starts to recover.

Broader Implications for DeFi Security

The Kelp DAO hack is a stark reminder of the risks in DeFi. Liquid restaking tokens, while innovative, introduce new attack vectors. The exploit targeted a vulnerability in the minting process, which is a common weak point in DeFi protocols. This event will likely lead to increased scrutiny of smart contract audits and risk management practices.

Industry experts have noted that the rapid response from Aave, Lido, and Ether.fi is a positive sign for the ecosystem. However, the hack also highlights the need for better insurance mechanisms and emergency response plans. DeFi protocols must work together to create a more resilient infrastructure.

Expert Analysis: The Importance of Coordinated Response

According to blockchain security analysts, the ‘DeFi United’ initiative is a model for future crisis management. By pooling resources and acting quickly, the protocols have minimized the damage from the hack. The focus on stabilizing rsETH, rather than recovering the stolen funds, is a pragmatic approach that prioritizes the health of the ecosystem.

However, experts also caution that the hack could have long-term effects on the liquid restaking sector. Investors may become more cautious about using rsETH and similar tokens as collateral. This could slow the growth of the restaking market, which has been a major trend in 2025.

Conclusion

The Kelp DAO hack has triggered a significant response from the DeFi community, with Aave, Lido, and Ether.fi launching the ‘DeFi United’ initiative to restore rsETH stability. The coordinated relief fund, totaling over $28 million, aims to provide liquidity and restore confidence in the token. While the hack exposed vulnerabilities in the liquid restaking model, the rapid and collaborative response demonstrates the resilience of the DeFi ecosystem. Moving forward, protocols will need to strengthen security measures and develop better crisis management plans to protect users and maintain trust.
