Aikido Security Analysis Platform — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Aikido Security Analysis Platform (Agent Skill) and scored it 45/100 (orange). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 20 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

Security analysis platform for [Aiken](https://aiken-lang.org/) smart contracts on Cardano.
Aikido goes beyond static analysis. It combines a 75-detector suite with SMT verification, transaction simulation, compliance analysis, protocol pattern detection, and grammar-aware fuzzing to find vulnerabilities in Aiken smart contracts before they reach mainnet. Multi-lane analysis cross-correlates evidence across techniques, producing findings with source context, severity ratings, CWE/CWC classifications, and actionable remediation guidance.
Built in Rust. Fast. Zero configuration required.
Cardano smart contracts are immutable once deployed. A vulnerability in production means lost funds with no recourse. Manual audits are expensive, slow, and bottlenecked. Aikido catches the classes of bugs that auditors find most often - double satisfaction, missing signature checks, unbounded iteration, unsafe datum handling - automatically, in seconds.

AIKIDO v0.3.1 Static Analysis Report
Project: test/simple-treasury v0.1.0
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
[CRITICAL] (definite) double-satisfaction - Handler treasury.spend iterates
outputs without own OutputReference - validators/treasury.ak:23
Spend handler accesses tx.outputs but never uses __own_ref to identify
its own input. An attacker can satisfy multiple script inputs with a
single output, draining funds.

|---|---|
| Detector Suite | Cross-module interprocedural analysis, taint tracking, symbolic execution, delegation-aware suppression, transitive signal merging, datum continuity tracking |
| Compliance | Securify2-style dual-pattern system: every security property has compliance (safe) and violation (unsafe) patterns. 10 security property variants |
| SMT Verification | Solver-independent interface with Cardano domain axioms (value conservation, signature semantics, minting policy). Constraint solving for reachability |
| Tx Simulation | ScriptContext builder generates concrete exploit scenarios. Tests 6 detector categories against simulated transactions |
| Protocol Detection | Automatic DeFi protocol classification (DEX, Lending, Staking, DAO, NFT, Options, Escrow). Token flow and authority analysis |
| Fuzz Lane | Grammar-aware Cardano transaction generation, Echidna-style stateful protocol fuzzing, deterministic PRNG |
Supporting modules: CWC Registry (30 entries mapping all 75 detectors), Scorecard (Experimental -> Beta -> Stable promotion with quality gates), SSA IR (phi nodes, dominators, use-def chains).
