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, with the final outcome dependent on how the situation is resolved. The incident centers on 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 forging a valid transfer message, resulting in the creation of new tokens without backing. The attacker then deposited the tokens into Aave as collateral and borrowed approximately $190 million in ETH and related assets. Aave Labs has taken steps to contain the risk, including freezing rsETH markets and halting new borrowing. The outcome now depends on how Kelp handles the shortfall, with two possible scenarios: a 15% depegging of the token if losses are spread across all rsETH holders, resulting in around $124 million in bad debt for Aave, or a more severe impact if losses are isolated to Layer 2 networks, resulting in roughly $230 million in bad debt. The exploit has raised concerns about the security of interconnected DeFi infrastructure and has led to a significant withdrawal of funds from Aave, with around $6 billion in total value locked withdrawn following the incident.
