This highlights the systemic risk introduced when decentralized finance infrastructure relies on third-party operators — a compromise or instability in one node operator can ripple across partner protocols and their users. The incident underscores that 'non-custodial' does not mean 'risk-free,' as infrastructure-level vulnerabilities can still result in financial penalties such as missed rewards and slashing risk. Proactive exits, while protective, demonstrate the cost of reactive security postures versus preventive ones.
