Aave Faces Potential Losses of Up to $230 Million Following Kelp DAO Bridge Exploit

A recent exploit of the Kelp DAO and LayerZero bridge has put lending protocol Aave at risk of losing up to $230 million, depending on the outcome of the situation. The incident revolves around rsETH, a liquid restaking token issued by KelpDAO, which relies on a bridge mechanism to transfer tokens between blockchains. An attacker manipulated this setup by creating a forged transfer message, resulting in the creation of new tokens without backing. The attacker then deposited these tokens into Aave as collateral and borrowed approximately $190 million in ETH and related assets. Aave has taken steps to contain the risk, including freezing rsETH markets and halting new borrowing. The outcome now depends on how Kelp DAO allocates the shortfall, with possible losses ranging from $124 million to $230 million. The exploit exposed weaknesses in Kelp's verification process using LayerZero, allowing the attacker to extract value from the system. In response to the incident, users have withdrawn around $6 billion in total value locked from Aave, highlighting concerns about the safety of interconnected DeFi infrastructure.
