Our Security Solutions

A secure system begins with a solid foundation. Our Architecture Assessment service evaluates your smart contract system's overall design and structure before it's finalized or deployed.

Our team thoroughly reviews your architecture, comparing it against proven design patterns observed in the market and documented in academic research. We assess critical components such as upgradeability, modularity, authorization flows, dependency management, and trust assumptions, ensuring they align with industry best practices in software engineering and security.

This process helps identify architectural weaknesses early, reduce technical debt, and set a clear path for secure and maintainable development. Whether you're designing from scratch or refactoring an existing system, this assessment provides deep insights to elevate your protocol's security posture.

Security is not a final step — it's a continuous process. Our Security Assistance During Development service provides ongoing support to your team throughout the development lifecycle, helping you build securely from day one.

In this engagement model, our experts are available for a set number of hours per day or week to review newly developed code, validate design decisions, and offer real-time guidance on security-critical aspects of the system. This close collaboration reduces the risk of introducing vulnerabilities early on and accelerates the feedback loop between developers and security professionals.

This service is ideal for fast-moving teams who want to embed security into their development workflow without slowing down. It fosters better engineering habits, ensures your codebase stays audit-ready, and often leads to shorter, more efficient final audits.

Zero-knowledge (ZK) systems require a specialized security approach. Our Zero-Knowledge Audits focus on reviewing the correctness, soundness, and safety of ZK circuits, cryptographic assumptions, and protocol-level logic.

We apply deep expertise in applied cryptography, formal verification, and protocol design to identify flaws that are often invisible to traditional auditors. Our team evaluates the structure of your proving system, checks the correctness of your constraint systems, and ensures your circuits meet the desired security guarantees. We also analyze interactions between the ZK component and the rest of your system.

This service is tailored for projects using SNARKs, STARKs, zkVMs, privacy-preserving mechanisms, and scaling solutions like zkRollups. Whether designing custom circuits or integrating a proving system into a broader architecture, our audit ensures your ZK stack is secure, efficient, and ready for production.

Smart contract security doesn't live in isolation. Our Web2 Audits service focuses on securing the traditional components of your application stack, including APIs, backend services, frontends, databases, authentication flows, and cloud configurations.

We take a comprehensive, attacker-minded approach to identify issues such as broken access control, insecure integrations with blockchain components, improper key management, and exposure of sensitive user data. Our methodology blends manual review with automated tooling and draws from years of experience in both Web2 and Web3 ecosystems.

As AI-driven systems become integral to modern applications, the security of these algorithms and data pipelines is paramount. Our AI Security Audits meticulously assess every layer of your AI infrastructure — from model integrity and data handling to algorithmic fairness and decision transparency.

Leveraging cutting-edge techniques and industry best practices, our experts evaluate potential risks in training data, model configurations, and deployment environments. We scrutinize the resilience of your systems against adversarial attacks, data poisoning, and bias exploitation, ensuring that every component is robustly safeguarded.

This service is tailored for enterprises deploying machine learning models, natural language processing systems, and computer vision technologies where the stakes are high and the threat landscape is constantly evolving.

Formal Verification provides the highest level of assurance. This service uses mathematical methods to prove that your smart contracts behave exactly as intended.

Our team works closely with you to define precise specifications of your system's intended properties. We then use industry-leading formal methods tools to produce machine-checkable proofs that these properties hold for all inputs and state transitions.

Formal Verification is particularly valuable for protocols that handle large amounts of value, require complex invariants, or serve as critical infrastructure, such as L1s, bridges, rollups, and financial primitives.

Quality assurance (QA) is a critical part of audits as it helps ensure the process and the resulting audit report are accurate. At Chain+, the QA processes are rigorous and designed to ensure that the audit work meets the highest standards, ensuring consistency in the process and the resulting comprehensive audit report.

QA processes also help identify areas for improvement in the audit process, increasing efficiency and effectiveness and leading to higher-quality audit reports. Stakeholders often rely on audit reports to decide whether to invest in a project, so meeting their expectations is essential to maintaining trust and confidence.
