Final quotes factor in codebase complexity, language / ecosystem, documentation quality, turnaround urgency, and several other engagement-specific variables. The numbers above are baselines — submit your repo for an exact quote.

Built by security researchers, for Web3 founders.

Traditional audit firms bill for reviewer-weeks. Cevanex uses LLMs to compress the low-value passes — parsing, triage, cross-contract trace — so human reviewers spend their hours on the findings that actually matter. Same rigour, a fraction of the cost.

WHAT WE BUILT

A layered audit pipeline

Multi-stage static analysis, call-graph reasoning, false-positive filtering, and LLM-assisted logic review — wired together so reviewers only see findings that survived multiple checks.

WHY IT'S CHEAPER

LLMs do the mechanical parts

Parsing, cross-referencing, boilerplate triage — the parts that cost reviewer-hours without finding bugs — run automatically. The human reviewer lands on an already-narrowed surface.

HOW WE'RE HONEST

Skin in the game

Low base + bounty per verified finding. If our pipeline doesn't catch real bugs, you pay the floor. If it does, we share in the value delivered — same incentives as a bounty hunter.
