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 impact hinging on the resolution of the situation. According to a report published by Aave Labs and LlamaRisk on the Aave governance forum, 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 took advantage of this setup by creating a forged transfer message that appeared legitimate, resulting in the creation of new tokens without backing. The attacker then deposited a significant portion of these tokens into Aave as collateral and borrowed approximately $190 million in ETH and related assets. Aave has taken swift action to mitigate the risk, freezing rsETH markets and halting new borrowing against the asset. The outcome is now largely dependent on how Kelp handles the shortfall, with potential losses ranging from $124 million to $230 million. The exploit has raised concerns about the security of interconnected DeFi infrastructure and has led to a significant withdrawal of funds from Aave, totaling around $6 billion in total value locked.
