Bug Bounty-Grade Analysis for Circom

Skip the expensive audit waitlist. Get instant, expert-level vulnerability detection powered by 15+ specialized AI agents built on real bugs we've found in production circuits.

Pre-Audit or Post-Audit. Your Call.

Use zkao to catch low-hanging fruit before paying $100k+ for human auditors, or complement your existing audit with continuous scanning. Either way, you ship more secure circuits.

1

Connect Your Repo

Point zkao at your GitHub repository. We'll automatically detect your Circom circuits and set up the analysis pipeline.

2

15+ Agents Go to Work

Each agent specializes in a different vulnerability class — under-constrained signals, unsafe assignments, range check gaps, and more.

3

Get Actionable Findings

Receive detailed reports with exact line numbers, severity ratings, and fix recommendations. No fluff, no false positive spam.

Beyond Static Analysis

Our agents understand circuit semantics, trace data flow across templates, and catch logic bugs that static analysis tools miss.

CRITICAL

Under-Constrained Signals

Signals that can take unintended values, breaking soundness

HIGH

Unsafe <-- vs <==

Assignment without constraint, allowing witness manipulation

HIGH

Range Check Gaps

Missing bounds checks that enable overflow attacks

MEDIUM

Non-Deterministic Witness

Witness generation that varies across runs

Gets Smarter Every Month

This isn't a static tool. As LLMs improve, zkao improves. We're constantly refining our agents based on the latest vulnerability patterns we discover in real audits.

  • Continuously improved with findings from real audits
  • Automatic improvements from LLM updates
  • Your scans get better without lifting a finger

Let's Be Honest About Bug Bounties

Bug bounty platforms in 2025: AI agents submitting findings to AI agents triaging findings, with humans occasionally approving payments. You're paying middlemen for what you could run yourself.

“Skip the theater. Get bug-bounty-grade findings directly — no spam, no duplicates, no 'AI-generated but we promise a human reviewed it' disclaimers.”

WHO WE ARE

Built by zkSecurity

We're the team protocols trust for their most critical ZK audits. Solana, Ethereum, Cardano, Sui — we've seen the bugs that break production systems. Now we're packaging that expertise into automated agents.

zkao isn't a generic AI tool. It's built by auditors who've spent years in the trenches, informed by the exact vulnerability patterns we find in real engagements.
