Frequently Asked Questions
How long does a manual audit take?
Most audits complete in 1–3 weeks depending on codebase complexity. We provide a timeline estimate during the initial scoping call within 24–48 hours of submission.
What chains do you support?
We support EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base, etc.), Solana, and multi-chain protocols. If your chain isn’t listed, reach out — we likely support it.
Do I still need a manual audit if I use your automated tool?
Automated scanning catches common vulnerabilities fast, but manual audits uncover complex logic bugs, economic exploits, and protocol-level risks that automated tools miss. We recommend both for maximum coverage.
What happens if new vulnerabilities are found after launch?
Your audit includes 1 month of continuous automated scanning post-launch. If new issues surface, we alert you immediately with actionable remediation steps.
How does your price compare to Hacken or Trail of Bits?
Traditional firms charge $50k–$150k for equivalent coverage. Our combination of advanced tooling and expert researchers lets us start at $5,000, up to 70% more affordable without compromising depth.
What's the difference between manual and continuous scanning?
A manual audit is a deep, point-in-time review by human experts. Continuous scanning monitors your contracts automatically after deployment, catching regressions and new attack vectors as they emerge.
