Aave outlines steps to rebuild rsETH collateral.

Returned tokens are sent to the DeFi United multisig wallet, redeemed for ETH and used to cover shortages in affected markets.

Ave announced a recovery plan following the April 18 exploit that affected liquid markets and collateral space at several chains.

The update explains how DeFi United, a group of ecosystem participants, intends to restore support for rsETH and bring the affected markets back to normal.

The issue began when an attacker exploited a vulnerability in the rsETH bridge from Unichain to Ethereum, allowing fake transactions to take place on Ethereum. So, 116,500 rETH was released to several addresses, some used as collateral on Aave 3 and some bridged to Arbitrum. Preliminary damage control measures include the Arbitrum Security Council freezing 30,766 ETH linked to the exploit. However, this still left a large balance and had a significant impact on the markets.

Currently, about 107,000 rETH of the stolen amount is locked in active slots on Aave and Compound. To fix this, the protocol developed a coordinated industry response at the initiative of Diffie United, later sharing the detailed procedure on social media, corresponding to the expected value of 1.017 ETH to stimulate the support of the token.

According to Ave, the plan is to gradually convert that ETH to rETH and put it in the bridge lockbox, which will allow the system to safely continue its normal operation. At the same time, LayerZero and KelpDAO have added additional security measures to reduce the risk of similar issues occurring again.

According to the article posted on X, Aave works on cleaning up the affected areas through management proposals on Ethereum and Arbitrum. The process also temporarily adjusts the price of rsETH to achieve easy liquidity.

The protocol sends the returned tokens to a multi-sig wallet held by DeFi United, which can be redeemed for ETH through the Kelp standard process and used to cover the shortfall in the affected markets.

The firm estimates that these efforts will help it recover about 13,000 ETH on Aave, while Compound will return about 16,776 ETH. He also explained that all WETH and rsETH reserves on Ethereum Core, Arbitrum, Base, Mantle and Linea will remain frozen for the duration.

Ave warned that while the process aims to restore rETH without distributing losses to users, it comes with some performance risks. For one, the outcome depends on whether the protocol receives the required regulatory approvals. Another challenge is the possibility of the attacker interfering with the recovery process. In addition, the new security measures should be effective after they are fully implemented.

The project team has followed this plan to fully restore rETH and ensure that it will fix the markets.

“The successful coordinated execution of these measures as planned will ensure that rETH support is fully restored and all affected markets are stabilized.”
