$3.1B lost to Web3 exploits in H1 2025

We found the $223M Cetus hack
before it happened.

800+ attack patterns. 20 proprietary Sui/Move CLMM detectors. Tri-AI debate engine. Your code scanned in minutes, not weeks.

Proof of detection
Cetus Protocol — scanned before the hack

Pre-hack code (commit 4029e47). Himaya flagged the exact overflow that drained $223M.

How it works
8-phase security pipeline

Static analysis + AI threat modelling + adversarial debate. Every finding validated before it reaches your report.

01-02

Parse + 800-pattern static scan

Auto-detect language. Run 800 CVE patterns across all source files.

Includes 20 proprietary static detectors built specifically for Sui/Aptos CLMM architecture — reward sniping, tick boundary overflow, flash swap reentry, oracle manipulation, and 16 more.
No AI cost
03

AI protocol threat model

Expert AI ingests all code (1M token context). Builds invariants, attack surfaces, and value-at-risk map.

Gemini 2.5 Flash
3.5

Call graph + multi-step attack synthesis

Synthesizes exploit sequences across 6 modes: flash loans, sandwich, state ordering, privilege escalation, composability, callback exploitation.

DeepSeek V3
04

Per-file zero-day hunt

Hunter AI scans each file for novel vulnerabilities no pattern database covers. 3 hypotheses per file.

DeepSeek Reasoner
05

Tri-AI debate: Hunter → Critic → Judge

3-round adversarial debate. Only findings that survive all three AIs reach your report. False positives eliminated.

PoC generation + report + gas optimization

Runnable exploit test code, detailed PDF report with severity scores, attack steps, and fix guidance.

The tri-AI debate engine

No other scanner validates findings through adversarial AI debate. This is how we eliminate false positives.

H Hunter (DeepSeek Reasoner)

checked_shlw() uses bitmask 0xFFFFFFFFFFFFFFFF << 192 with > instead of >=. When high bits exactly equal the mask, the function returns the truncated value instead of aborting. An attacker can craft a liquidity value that overflows silently.

C Critic (DeepSeek R1)

Checking: (1) Can u256 values have high bits == mask exactly? Yes. (2) Any upstream guard? None found. (3) Can attacker control input? Yes, via crafted liquidity. CONFIRMED.

J Judge (Claude Sonnet 4.6)

Mathematical analysis and access path are both sound. The bitmask comparison is off-by-one. No upstream guard exists. CONFIRMED — CRITICAL. Confidence: 0.92.

Zero-leak guarantee

Your code is the most sensitive thing you own. Here's exactly how we handle it.

✓ We do not train models on your code. Ever.
✓ Enterprise-grade API endpoints with zero-data-retention policies (Anthropic, Google, DeepSeek).
✓ Your source code is wiped from our systems the second the report generates.
✓ NDA available on request before engagement.
✓ On-prem option available for enterprise (you run Himaya on your own infra).

Built by a security researcher, not a marketing team

I built Himaya because I saw audited protocols still getting hacked. The Cetus scan above isn't a demo — it's what I ran against real pre-hack code and found the real root cause. I'm offering concierge pre-audits because I want to prove the tool works on your code, not just mine.

"No tool can guarantee 100% secure code. Himaya is your first line of defense — catching known patterns, discovering novel attack paths, and validating with adversarial AI. We reduce your audit scope and cost. We complement, not replace, professional security review."
