Overview

# Krait

**AI-assisted security verification for Solidity smart contracts.** Not a scanner — a structured methodology with 101 heuristics, 26 analysis modules, and 8 kill gates, tested blind against 50 Code4rena contests at **100% precision**. Runs inside [Claude Code](https://docs.anthropic.com/en/docs/claude-code). Free.

### At a Glance

| | | |---|---| | **Current version** | v8.2 (kill-gate parity, Impact Premise, rescan + per-contract recall phases) | | **Measured baseline** | **v8** — 50 contests. v8.1/v8.2 are not yet re-measured ([why](METHODOLOGY.md#-unvalidated-since-the-v8-baseline)) | | **Detection angles** | 16 per function (4 lenses × 4 mindsets) | | **Heuristics** | 43 original + 58 extended (from open-source community) | | **Analysis modules** | 15 deep-dive module files + 26 inline modules (A-X) | | **Audit-trail rules** | R8 / R10 / R11 / R12 / R15 / R16 — exercised per finding (v8.1) | | **Domain primers** | 7 (DEX, Lending, Staking, GameFi, Bridges, Proxies, Wallets) | | **Kill gates** | 8 automatic + Impact Premise + 10 FP patterns (identical on both surfaces, parity-tested) | | **Shadow audits** | 50 contests, 100% precision, 0 FPs/contest (v8 baseline) | | **Full methodology** | [`METHODOLOGY.md`](METHODOLOGY.md) — every technique, publicly documented |

### Two Local Surfaces, One Web Platform

This repo ships **two** Claude Code surfaces. They answer different questions, and you can run either or both.

| | **Audit pipeline** (`/krait`) | **Checklist plugin** (`/krait:scan`) | |---|---|---| | Question it answers | "What bugs are in this code?" | "Am I ready for an audit?" | | Method | Multi-phase adversarial reasoning from first principles | 845 curated checks across 39 DeFi verticals | | Output | Exploit traces with file:line, severity, suggested fix | Per-check verdicts, importable assessment JSON | | Bar | Zero false positives — 8 kill gates try to disprove every finding | Coverage — every applicable check gets a verdict | | Lives in | `
