Aave Faces Potential Losses of Up to $230 Million Due to 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, with the final impact hinging on how the situation is resolved. According to a report by Aave Labs and LlamaRisk, the incident centers on rsETH, a liquid restaking token issued by KelpDAO, which relies on a bridge mechanism to move tokens between blockchains. An attacker manipulated this setup by forging a valid-looking 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, but the outcome now depends on how Kelp handles the shortfall. If losses are spread across all rsETH holders, Aave may face around $124 million in bad debt, while isolating losses to Layer 2 networks could lead to $230 million in bad debt. The exploit has raised concerns about the safety of interconnected DeFi infrastructure and has led to a significant withdrawal of funds from Aave, with around $6 billion in total value locked being withdrawn. Discussions are underway to address potential losses, with Kelp's DAO treasury holding approximately $181 million in assets.
