Crypto Coalition Unveils Plan to Mitigate Aave Token Exploit

The aftermath of a $300 million exploit typically doesn't come with a straightforward solution. However, the group leading the Kelp DAO recovery efforts is attempting to create one. DeFi United, a coalition of multiple blockchain projects and crypto ecosystem individuals, has devised a detailed, step-by-step plan to restore the backing of rsETH after this month's Kelp DAO hack, which released over 116,000 unaccounted-for tokens. The proposal, shared on Aave's official X account, resembles a coordinated damage control operation, relying heavily on Aave's infrastructure to rectify the situation and stabilize markets. The incident originated on April 18, when an attacker exploited a vulnerability in rsETH's bridge, forging a legitimate-looking message that tricked the Ethereum side of the system into releasing 116,500 rsETH, creating a large batch of tokens without backing. These tokens were dispersed across multiple wallets and utilized across DeFi, with a significant portion used as collateral on Aave and other lending platforms. As a result, protocols like Aave found themselves holding collateral that was temporarily unbacked. According to the proposal, most of the exploited funds remain active, with approximately 107,000 of the original 116,500 rsETH still tied up in positions across Aave and Compound. This presents two pressing issues: restoring rsETH's backing and unwinding the loans created using the extra tokens. DeFi United's proposal aims to address both problems simultaneously. To restore backing, the group claims to have secured sufficient ETH commitments to fully re-collateralize rsETH, which will be fed back into the system in stages. Meanwhile, attention shifts to the lending markets where the damage is most evident. Rather than allowing the situation to unfold chaotically, the plan involves carefully unwinding the mess. A key aspect of this process involves dealing with the positions the attacker opened on Aave, which are essentially loans backed by rsETH that should not have existed. By temporarily adjusting rsETH's valuation within the system, these bad positions can be liquidated or closed more smoothly, allowing the underlying assets to be recovered. The proposal estimates that this could free up around 13,000 ETH from Aave alone. Once this collateral is recovered, it will be converted into ETH and used to cover the shortfall created by the exploit. The process is not without risk, relying on governance approvals across multiple chains, the successful deployment of committed funds, and a smooth execution of the unwind. Nevertheless, the plan represents a more coordinated response than DeFi has often managed previously. If executed as intended, the ultimate goal is to fully restore rsETH's backing and stabilize all affected markets.
