Continuous Smart Contract Security for Enterprise Teams

Kairo CLI

Scan any Foundry, Hardhat, or Anchor project from the command line. The scanner runs entirely on your machine — no code is uploaded, no network calls during analysis.

GitHub Action

Automatically scan every pull request with deep AI analysis. Block merges when critical vulnerabilities are found. Post rich PR comments with attack graphs, exploitability matrix, and inline code annotations. Upgrade to full penetration testing by adding a PR label.

Penetration Testing & Fuzzing

Go beyond static analysis with automated penetration testing and fuzz testing. Our pentest engine generates attack scenarios, attempts real exploits against your contracts, and reports verified vulnerabilities with proof-of-concept code. Property-based fuzzing discovers edge cases that manual testing misses.

Security Dashboard

Centralized view of all findings across projects, scans, and team members. Track security posture over time. Export reports for compliance.

On-Chain Monitoring

Real-time monitoring of deployed contracts across all supported chains. Get instant alerts when suspicious transactions, abnormal token movements, or potential exploits are detected. Monitor contract interactions, track governance changes, and verify upgrade safety — all from a single dashboard.

Code Stays Local

Most security platforms require uploading source code to their cloud for analysis. This is a non-starter for banks, federal institutions, and any team with compliance requirements. Kairo's CLI and GitHub Action run analysis entirely within your infrastructure. Only findings metadata — never source code — is optionally synced to the dashboard.

Continuous, Not One-Time

Point-in-time audits expire the moment code changes. Kairo scans on every commit, every PR, and every deployment. Security is a continuous process, not a checkbox. Your team gets 24/7 coverage without scheduling audits or waiting in backlogs.

Project-Aware Analysis

Generic static analyzers treat every file the same. Kairo understands your project structure — Foundry remappings, Hardhat configs, Anchor workspace layouts, Cargo.toml dependencies, source directories, test exclusions, and library dependencies. This context-aware approach works across EVM and Solana ecosystems, dramatically reducing false positives and surfacing findings that matter.

Multi-Engine Scanning

Instead of relying on a single analysis method, Kairo layers pattern matching, Slither integration, and AI-powered analysis together. Each engine catches different vulnerability classes. Combined, they provide coverage that no single tool achieves alone.

Developer Workflow, Not Security Theater

Kairo integrates where developers already work: the terminal and GitHub. No separate portals to check, no context-switching to a security dashboard for day-to-day work. Findings appear as PR annotations, CLI output, and SARIF reports that feed directly into GitHub Code Scanning.

Deployment Gates

Other tools report findings but leave enforcement to the developer. Kairo provides configurable deployment gates — ALLOW, WARN, or BLOCK — that prevent vulnerable code from reaching production. Set your threshold and let the pipeline enforce it.

Pass 1: Static Pattern Analysis

Context-aware pattern matching against vulnerability signatures — not simple regex. The engine analyzes surrounding code within configurable context windows (200-500 characters) to detect protective patterns like reentrancy guards, nonce tracking, and gas limits. If a function already has a nonReentrant modifier, the confidence score for a reentrancy finding drops by 70%. If EIP-712 signatures include chain ID and nonce validation, replay attack confidence drops by 60%.

Pass 2: Dynamic & Symbolic Execution

Integration with Slither and Mythril for deep analysis that goes beyond pattern matching. Slither performs control flow analysis, data dependency tracking, and taint propagation across function boundaries. Symbolic execution explores all reachable paths through your contracts, catching edge cases that static analysis cannot — integer overflows on specific input ranges, state-dependent access control bypasses, and cross-function reentrancy through unexpected callback chains.

Pass 3: ML Semantic Analysis & Triage

Code is chunked at function boundaries using brace-depth tracking to preserve semantic coherence, then embedded into a vector space. These embeddings are compared against a database of known vulnerability patterns using pgvector similarity search. Findings from all three passes are then triaged by a weighted confidence model — severity, source agreement, and contextual signals determine what surfaces to the developer and what gets suppressed as noise.

EVM / Solidity Analysis

Full support for Solidity smart contracts across all EVM-compatible chains. Integrates with Foundry, Hardhat, and Truffle project structures. Slither and Mythril provide deep static and symbolic analysis. Pattern matching covers 150+ EVM-specific vulnerability signatures including reentrancy, flash loan attacks, oracle manipulation, and MEV exposure.

Solana / Rust / Anchor Analysis

Purpose-built analysis for Solana programs written in Rust and Anchor. Kairo detects Solana-specific vulnerability classes that EVM tools completely miss: missing signer checks, account validation flaws, PDA seed collisions, integer overflow in token arithmetic, unchecked cross-program invocations, and missing owner/authority verification. The scanner understands Anchor's account constraints, program-derived addresses, and instruction-level access control.
