The New Guard of Web3 Cybersecurity: Nex Labs and Olympix

External audits, while important, aren't a perfect solution for Web3 cybersecurity. Recent high-profile hacks on audited projects like Penpie, Ronin, and Euler demonstrate that relying solely on these audits leaves significant vulnerabilities unaddressed. The traditional model needs to evolve beyond just external reviews.
