Our team includes PhD-level cryptographers who have spent years developing and cryptanalyzing complex cryptographic protocols (for example, see our published analysis and contributions to the EDHOC protocol). At the same time, we aren't solely academics. Half of our team comes from a traditional software and security background. We bring the best of both worlds; we know math, theory, software, and real-world systems.
Book a complimentary one-hour meeting with one of our engineers to dive into a challenging technical issue, explore
tooling options, and gain valuable insights directly from our experts. This session is purely technical—no sales
talk, just a focused discussion that showcases our depth, talent, and capabilities.
Cryptography is uniquely sensitive to design flaws, which can lead to severe vulnerabilities that are often subtle and hard to detect without specialized knowledge. Our team, skilled in theoretical and applied cryptography, assesses your design documents before you begin implementation, helping you avoid costly mistakes and rebuilds.

Scroll, a company extending Ethereum’s capabilities through zero-knowledge (ZK) technology and EVM compatibility faced the challenge of auditing its zkEVM circuits. Recognizing the need for advanced expertise and impactful recommendations, Scroll turned to Trail of Bits for several key reasons:
Learn how our comprehensive approach and expert insights empowered Scroll to strengthen their ZK circuit
security and development practices.
Our Cryptography team develops and maintains multiple open-source tools, such as Tlspuffin and Circomspect, which we use in our internal assessments. We have also created custom rules for CodeQL. View our custom CodeQL rules on GitHub.
We are committed to sharing our knowledge with the community. We share our research and expertise whenever possible through our blog and in research papers. One of our most recent publications is Weak Fiat-Shamir attacks against modern proof systems.
Our cryptography team has developed and continues to maintain ZKDocs, offering comprehensive, detailed, and interactive documentation focused on ZKP systems and related cryptographic primitives.
Unlike many firms that follow a predefined checklist that limits the scope and capabilities, our assessments don't look to check boxes but discover the root causes of security weaknesses identified. This approach allows us to provide nuanced, actionable insights that do more than fix the immediate problems—they also enhance the system's overall resilience and security for the future. By focusing on the root causes and broader implications of security vulnerabilities, we empower our clients to not just respond to bugs but to develop stronger, more resilient software design, development, and coding practices.
