Crypto audits give investors false sense of security as Q3 hacks cost $1.18 billion, Hacken says

Smart-contract audits became standard practice after the 2016 DAO hack and the wave of 2021 DeFi exploits, with firms like Hacken, CertiK and Trail of Bits certifying code before launch. The model assumes a one-time review catches flaws before deployment. Hacken's own data shows the opposite pattern now: smart-contract exploits took a larger share of Q3 losses than in Q2, even as projects kept citing completed audits as proof of safety.

Teams that rely on a single audit certificate now face pressure to adopt continuous monitoring, since Hacken found 77% of Q3 losses traced to compromised suppliers, delayed patches, or systems that sat outside the last review. Investors who treat an audit badge as a green light lose that shortcut; they must instead track whether a protocol's dependencies and post-launch changes stayed in scope. Security vendors offering ongoing monitoring, rather than one-off reports, stand to gain business from this shift.

An audit that only inspects code at one moment cannot vouch for a supply chain that changes afterward, and Hacken's own framing, that audits give a false sense of security, is a pointed admission from inside the industry it sells to. The deeper trade-off is between the comfort of a certificate and the cost of continuous verification, which smaller projects may not afford. Treating a single report as permanent clearance looks increasingly indefensible given where the losses actually originated. (per ambcrypto.com)

The figure to track is whether smart-contract exploits keep gaining share of total losses when Hacken publishes its Q4 2026 data, which would confirm this quarter's shift is a trend rather than a blip. A reversal would suggest the industry closed the gap between audits and live systems; a repeat of the 77% supply-chain and delayed-fix pattern would strengthen the case that periodic audits are no longer sufficient on their own.
