Michael Egorov, founder of Curve, expressed on the X platform that DeFi will remain the future of the global financial system, but recent avoidable security incidents—largely stemming from centralized single points of failure—are severely damaging the industry's development. Citing the Aave and rsETH incidents as examples, he pointed out that while multiple parties claimed 'the system is operating normally,' users were unable to withdraw their funds, exposing issues of infrastructure dependency and dispersed responsibility. The crypto industry should work to reduce single point of failure risks beforehand and, when unavoidable, distribute trust while sharing best practice configurations and security experiences. He called for the establishment of unified DeFi security standards and suggested that ecological institutions, including the Ethereum Foundation and Solana Foundation, take the lead in developing and validating principles and norms for safety.

On April 21, Kelp DAO officially reported on X regarding the theft incident, stating that the cause of the theft was the breach of two RPC nodes hosted by LayerZero, while a third RPC node suffered a DDoS attack. This was an attack targeting LayerZero's infrastructure, and Kelp's own system was not involved in the construction or operation of that infrastructure. The 1/1 DVN configuration is the scheme documented in LayerZero's documentation and is the default setting for all new OFT deployments. Kelp has been operating on LayerZero's infrastructure since January 2024 and has maintained open communication with the LayerZero team. During Kelp's expansion to Layer2, the DVN configuration issue was discussed, and the default configuration was explicitly confirmed to be appropriate at that time. Kelp's current top priority is to safeguard user interests and prevent risks from spreading within the DeFi ecosystem. The team is collaborating with various parties within the ecosystem to analyze the impact, seek support, and explore all possible mitigation solutions.
