Coalition Unveils Plan to Mitigate $300 Million Token Exploit Impact on Aave Users

The aftermath of a $300 million exploit typically doesn't come with a straightforward solution. However, DeFi United, a coalition comprising multiple blockchain projects and crypto ecosystem individuals, is attempting to provide one. The group has outlined a step-by-step plan to restore the backing of rsETH following this month's Kelp DAO hack, which sent shockwaves through DeFi lending markets by releasing over 116,000 unaccounted-for tokens. The proposal, shared on Aave's official X account, resembles a coordinated recovery effort, relying heavily on Aave's infrastructure to rectify the damage and stabilize the markets. The incident originated on April 18, when an attacker exploited a vulnerability in rsETH's bridge, forging a message that appeared legitimate and tricking the Ethereum side of the system into releasing 116,500 rsETH. This created a large batch of rsETH without backing, which were then dispersed across multiple wallets and utilized as collateral on Aave and other lending platforms. As a result, protocols like Aave found themselves holding collateral that was temporarily unbacked, leading to a systemic problem. 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. DeFi United's proposal aims to address both the restoration of rsETH's backing and the unwinding of loans created using the extra tokens. The group claims to have secured sufficient ETH commitments to fully re-collateralize rsETH, planning to feed the ETH back into the system in stages and convert it to rsETH to restore the token's backing. Simultaneously, the plan focuses on the lending markets where the damage is most visible. Rather than allowing the situation to unfold chaotically, the proposal suggests a controlled unwinding of the mess. A key aspect of this involves dealing with the positions the attacker opened on Aave, which are essentially loans backed by rsETH that should not have existed. To mitigate further market disruption, the proposal recommends temporarily adjusting rsETH's valuation within the system, enabling the liquidation or closure of these bad positions in a more controlled manner. As these positions are unwound, the underlying assets, such as ETH, can be recovered, potentially freeing up around 13,000 ETH from Aave alone. Once the collateral is recovered, it will be converted into ETH and used to cover the shortfall created by the exploit, effectively filling the hole left behind. While 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, the plan represents a more coordinated response than DeFi has often managed previously. If executed as intended, the ultimate goal is clear: the backing of rsETH will be fully restored, and all affected markets will be stabilized.
