Let's talk about onchain security risks. Smart contract vulnerabilities? They've been bleeding the industry dry for a decade now. Remember where it all kicked off? 2016 - The DAO exploit. That single incident set the tone for what became a costly pattern. Since then, hackers have siphoned billions from poorly audited protocols and flawed contract logic. We're talking about cumulative losses that would make traditional finance blush. The attack surface keeps expanding as more value flows onchain, yet many projects still rush deployment without rigorous security reviews. History repeats itself when lessons aren't learned.
