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

A recent bridge exploit involving Kelp DAO and LayerZero has put Aave at risk of losing up to $230 million, with the final impact dependent on how the situation is resolved. The exploit centered 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 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, leaving Aave exposed to potentially impaired collateral. In response, Aave Labs moved quickly to contain the risk by freezing rsETH markets and halting new borrowing against the asset. The outcome now depends largely on how Kelp handles the shortfall, with potential losses ranging from $124 million if spread across all rsETH holders to $230 million if isolated to Layer 2 networks. The incident has raised concerns about the security of interconnected DeFi infrastructure and the potential for undercollateralized loans.
