From smart contracts to complex financial infrastructure, Cantina delivers tailored security audits led by expert researchers and enhanced by AI security tools - accelerating threat discovery without compromising the expertise required to uncover critical vulnerabilities.
Choose from solo reviewers, modular teams, or competitive formats to match your workflow and risk profile.
Whether you’re building decentralized protocols, financial applications, or ecosystem infrastructure, Cantina offers scalable review formats. We match you with the right experts and ensure transparent, collaborative reviews to uncover vulnerabilities before they matter.
Our platform combines elite researchers with intelligent tooling - machine learning accelerates coverage while human judgment validates every finding.
Cantina Security Reviews are deep-dive, expert-led assessments of your codebase. We identify vulnerabilities across smart contracts, protocols, or infrastructure systems by matching you with solo reviewers, modular teams, or competitive reviewers based on your risk and workflow needs.
We specialize in smart contracts, DeFi applications, infrastructure protocols, financial systems, and Web3 tooling—but our expertise doesn't stop there. Cantina also supports Web2 security reviews, including backend systems, APIs, and integrations that interact with blockchain components. Whether your system is fully decentralized, hybrid, or includes traditional architecture, we provide a tailored review model to match your stack and threat profile.
All reviews are conducted by vetted experts with proven experience. Researchers like 0xRajeev, Haxatron, shotes, and Christoph Michel are just a few of the high-performing auditors on our platform—each with a public profile and a track record of high-severity discoveries. Many of them are also part of the Cantina Fellowship Program, which recognizes and rewards top contributors in our community.
We offer flexible formats, top-tier researcher access, real-time collaboration interfaces, and transparent issue tracking. Plus, all findings are delivered with rich metadata - severity levels, status, comments, and reviewer context - for clear remediation paths.
We start with a scoping call, assign the ideal researchers, then conduct the review using our secure and collaborative platform. Findings are tracked and triaged, and your team can engage directly with researchers throughout the process.
Yes! Many clients start with a security review, then launch a competition or bug bounty to widen coverage and catch edge cases. Combining layers strengthens your security posture and often qualifies you for added protection benefits.
Absolutely. We offer optional fix reviews, continuous review plans for large codebases, and bundled solutions for deeper engagement.
We've secured major Web3 organizations like Optimism, Morpho, Sushi, and Coinbase. Whether you're launching a new protocol or scaling an established platform, Cantina is built to support critical systems at every stage.

Spearbit provides high-end security reviews with teams hand-selected from a network of top Web3 security talent. Spearbit reviews must include a minimum of two Lead Security Researchers. These reviews are designed for depth and specialization, assessing some of the most complex decentralized systems in the ecosystem.
Cantina Reviews allow for more flexibility, providing you with a team of expert security researchers without Spearbit’s two Lead Security Researcher minimum. This model allows for faster onboarding and/or budget-flexibility while leveraging the same pool of expert security talent.
