AI Smart Contract Audit
Smart contract security audits used to take weeks and cost tens of thousands of dollars. AI has changed that. SmartContract.us combines Claude AI with industry-standard static analysis tools to produce a structured, professional-grade security report in under 60 seconds — for any verified contract on Ethereum, Polygon, Arbitrum, Base, or BNB Chain.
What an AI audit covers
Our AI audit pipeline runs two layers of analysis before Claude ever sees your contract:
- Vulnerability pattern scanner: 14 Solidity anti-pattern detectors check for reentrancy, access control flaws, integer overflow/underflow, unchecked return values, and more.
- Solhint linting: Code quality and best-practice violations surfaced automatically.
Claude then reads the full contract source and all scanner results, validates or refutes each finding, adds contextual analysis, and produces a structured v2 audit report including:
- A Trust Score (0–100) and risk level verdict.
- Deploy-readiness assessment with a specific recommendation.
- Findings with severity (Critical / High / Medium / Low / Informational), description, impact, and fix.
- Weighted sub-scores: Code Security, Access Control, Economic Risk, Operational Risk.
- Gas efficiency analysis and optimization suggestions.
- Investor summary including rug pull risk assessment.
- Developer notes with immediate action items and best practice violations.
How AI audits compare to manual audits
| Feature | AI Audit (SmartContract.us) | Professional Manual Audit |
|---|---|---|
| Speed | Under 60 seconds | 2–8 weeks |
| Cost | Free (1/day) or $59/month Pro | $20,000–$150,000+ |
| Known vulnerability patterns | Excellent | Excellent |
| Novel logic bugs | Good | Excellent |
| Protocol-level economic attacks | Good | Excellent |
| Repeat analysis during development | Practical (seconds) | Not practical (weeks) |
| Suitable for high-value mainnet launch | As a first pass | Yes |
When to use an AI audit
- During development: Run an AI audit after every significant code change to catch regressions early.
- Pre-audit preparation: Use AI audit findings to resolve low-hanging fruit before spending on a manual audit — this can significantly reduce manual audit scope and cost.
- Investor due diligence: Analyze any protocol's contracts before depositing funds.
- Lower-stakes contracts: For contracts holding under $100,000, an AI audit may be sufficient as the primary security review.
Multi-chain support
SmartContract.us supports contract analysis across five major chains: Ethereum, Polygon, Arbitrum, Base, and BNB Chain. Enter any verified contract address and select your chain — we fetch the source code automatically.
