Smart Contract Auditor Active

Kalvex predicts
how your smart contract|
will get hacked —
before you deploy.

150+ detectors — 69 regex patterns, Slither AST analysis, and Claude AI — run in parallel against your Solidity source, cross-referencing 30 historical DeFi exploits to deliver a verdict in under 40 seconds.

How It Works
From paste to verdict in 40 seconds.
01
Paste your Solidity contract
Drop your source code into the scanner. No wallet, no deployment, no account required.
02
69 regex + Slither AST + AI analyze it in parallel
Three engines run simultaneously: 69 regex pattern detectors, Slither AST analysis, and Claude AI for contextual threat modeling.
03
Get a DO NOT DEPLOY verdict with real exploit context
Every finding cites the real-world hack it matches — The DAO, Euler Finance, Poly Network. You know exactly what to fix and why it costs millions.
⬡
Detection Engine
150+ Vulnerability Detectors

Every scan runs all 150+ detectors simultaneously — 69 regex patterns + Slither AST + AI. Critical classes modeled from real exploits: Euler Finance ($197M), Cream Finance ($130M), The DAO ($60M).

⬡
Knowledge Base
30 Real Exploits. All Modeled.

Every detector traces its lineage to a real attack. When Kalvex flags reentrancy, it cites Euler Finance. When it flags oracle manipulation, it references Mango Markets.
