Meet Spearbit’s Security Researchers

Spearbit’s Lead Security Researchers (LSRs) are among the most trusted experts in Web3 security. With deep backgrounds across cryptography, protocol design, and offensive security, these individuals have been battle-tested across high-stakes audits, bounty programs, and competitive reviews. Now, they’re also available on Cantina, where their expertise is made accessible to teams at every stage of development.

Whether you’re preparing for a critical deployment, looking for a second set of eyes, or seeking specialist input, this researcher network represents the highest level of technical assurance available in the ecosystem.

What Makes a Spearbit Researcher Exceptional

Spearbit LSRs are selected through a rigorous onboarding process and peer-reviewed evaluations. Each researcher brings a unique combination of hands-on expertise and high-context thinking. You’re not just hiring a smart contract auditor - you’re gaining a strategic partner in security.

Researchers are selected based on:

  • A verified track record of impactful findings

  • Mastery of high-risk domains like ZK, DeFi, MEV, or cross-chain systems

  • Public contributions to open-source tooling or ecosystem security

  • High communication standards and collaborative experience across reviews

This expertise is continuously proven in real-world reviews and competitions across both Spearbit and Cantina.

FAQ

Can I request a specific researcher?

Yes. If you already know who you want to work with, you can request them directly during the contact flow.

Are Spearbit and Cantina researchers the same?

Yes. All Spearbit LSRs are available on Cantina, but not all Cantina contributors are LSRs. Spearbit researchers are the highest-performing, most trusted members of the wider network.

How often are researcher profiles updated?

Researcher profiles are continuously maintained as their reputation scores evolve, new findings are confirmed, and status changes. This ensures clients always see the most up-to-date view of performance and fit.

Can multiple researchers collaborate on the same engagement?

Yes. For complex reviews, we often assign teams of complementary researchers based on expertise areas. This ensures both depth and coverage across different components of your protocol or system.

What if my project requires a specific domain expertise (e.g., zk, formal verification)?

You can filter researchers by specialization and reputation, or work with our team to match you with individuals who have the exact background needed. Many of our LSRs are domain leaders in ZK, DeFi, MEV, and system design.
