This article was first published on The Bit Journal. A major exploit involving decentralized finance protocol Kelp DAO has sent shockwaves through the crypto lending ecosystem, with potential fallout threatening platforms like Aave.

During the weekend, hackers attacked Kelp DAO, draining an estimated 116,500 restaked Ether (rsETH), worth almost 293 million dollars, by breaching the infrastructure connected to LayerZero. The stolen funds were then used as collateral on Aave V3, enabling the hackers to borrow wrapped Ether (wETH), increasing the financial risk between the interconnected systems of DeFi.

Kelp DAO Losses Spread Across Networks

Risk modelling company LlamaRisk has since described two possible outcomes that may dictate the impact of the resultant bad debt of the Kelp DAO exploit on the ecosystem.

Update on rsETH incident:@LlamaRisk has published a report outlining the rsETH incident, the immediate actions taken, its impact on Aave, and potential paths forward.

All service providers have been working to assess the two potential bad debt scenarios on the Aave protocol.…

The Kelp DAO incident would spread losses to all rsETH holders on both Ethereum mainnet and layer-2 networks in the former scenario. This would reduce the exposure of Aave to an estimated bad debt of 123.7 million dollars, but may still result in a depegging of 15 percent of the rsETH against Ether. Analysts point out that wrapped Ether would absorb the majority of the losses in terms of dollar value, but the overall effect is likely to be cushioned by the fact that it has deep liquidity reserves.

The internal protection of Aave can also be applied. Its Umbrella security system might be used to mitigate some of the damage associated with the restaking protocol, especially since almost 43.7 million dollars worth of Aave-wrapped Ether (aWETH) is already in an unstaking cooldown period- which may allow money to be offered to stabilize the system.

Extreme Scenario Raises DeFi Systemic Risk

The second, more extreme case would focus the full financial loss of Kelp DAO on Ethereum layer-2 systems like Arbitrum and Mantle. In this instance, bad debt of Aave might soar to approximately 230.1 million, which would cause a great deal of systemic stress in those chains.

Although there is no certainty about Kelp DAO, Aave might possess some financial cushion. It is reported that the protocol has around 181 million in its treasury that can be used to cover up the losses in case of need.

Kelp DAO Assesses Impact After Exploit

In the meantime, Kelp DAO has said that it continues to assess the total financial impact and collaborates closely with partners such as Aave and LayerZero to figure out the least risky course of action before it can restart its operations following the protocol exploit.

Additional information shows that the exploit was based on a complex attack on the integration of Kelp DAO with the bridge infrastructure of LayerZero. Two of the validator nodes were compromised and a third one was disrupted through a distributed denial-of-service (DDoS) attack. This enabled the attacker to create an apparently valid transaction message, which led to the illegal minting of rsETH associated with Kelp DAO.

Kelp DAO Pauses Contracts After Exploit

Kelp DAO in turn responded by swiftly pausing all impacted smart contracts on Ethereum and its layer-2 networks. It also blacklisted wallets associated with the attacker, effectively preventing another theft of about 40,000 rsETH, which is worth an estimated 95 million.

The the protocol exploit highlights a long-standing weakness of decentralized finance the interconnectedness of protocols. A breach of only one component especially those that bridge cross chains can ripple out to cause liquidity stress, mass withdrawals, and systemic instability across the larger DeFi ecosystem.

Conclusion

The Kelp DAO exploit indicates the increasing systemic risks in decentralized finance, where interconnected platforms are susceptible to cascading failures. As Aave and other stakeholders calculate the damage, the event will increase the focus on cross-chain infrastructure and risk management practices throughout the DeFi ecosystem.

Summary

Hackers stole $293M from Kelp DAO via LayerZero breach, raising Aave bad debt concerns.
Aave exposure may range from $123.7M to $230.1M under different loss scenarios.
Kelp DAO paused contracts and investigates exploit with partners amid DeFi risk concerns.
