Smart contract audits used to cost weeks of expert time and serious money, and the new generation of AI tools just turned that into a one-hour scan that costs almost nothing.
That is the good news. The bad news is most crypto thefts never started with the code.
Manual smart contract audits have been a bottleneck for years, with projects paying six figures and waiting weeks to get a report - and most early-stage protocols skipped them entirely because they could not afford the bill.
AI changed the math. Alexander Urbelis, chief information security officer at ENS Labs, said the new tools are pushing "the price of a basic audit toward zero."
Coinbase has already built an autonomous workflow that pumps out formatted audit reports in 1 to 2 hours, using two Trail of Bits security skills in the first and third stages of the scan - making basic security checks accessible to projects that previously had none.

Most of crypto's biggest losses do not come from code bugs, and Urbelis pointed to the recent Drift compromise as proof.
The smart contract did exactly what it was told, but the attack was a months-long social engineering campaign that targeted trusted contributors and slowly walked them into giving up the keys.
The catch: AI cannot audit a phone call, catch a compromised laptop, or notice when a trusted developer has been pressured into pushing a malicious change.
Many of crypto's biggest losses come from the human layer - and AI auditing tools, no matter how fast or cheap, leave that part of the attack surface untouched.
The new normal is AI first, humans second. Machines handle the breadth, scanning thousands of contracts in hours, while humans handle the depth - reviewing the edge cases the model flags and making the calls about which findings actually matter.
Think of it like the metal detector at an airport. The machine catches the obvious stuff fast, but a human still has to look at the bag that beeps.
The bigger shift is not that audits got cheaper, but that "we couldn't afford an audit" no longer counts as a reason to skip one.
Anthropic, OpenAI, and the major exchanges are racing to lock down which builders get early access to the most capable models, with Coinbase and Binance reportedly negotiating for access to Anthropic's Mythos preview and Uniswap's founder Hayden Adams publicly asking for it.
The next 12 months will decide whether AI ends up as the crypto industry's best new defense or its fastest new weapon.
