Solo Audits - For Web3 Teams
The right solo auditor cuts costs while helping you secure your protocol.
- Cost-efficient – pay for expertise, not corporate overhead.
- Niche Expertise – I’ve audited projects across different web3 domains and only take work where I can add real value.
- Transparent – one auditor, clear accountability, publicly verifiable credibility.
A solo security review, especially early on, before further audits can help maximize ROI and save you $$$$$.
Let's talk. Reach out to me anytime and see whether a Solo Audit is the right fit for your project.
