The challenge

Why offchain code keeps you up at night

Endless, Complex Codebase

Offchain codebases are often complex and massive, making it difficult and expensive to ensure reliability and security.

Fixing in Production

While offchain components can be easily fixed after vulnerabilities are discovered, malicious actors can spot flaws before you do.

Frequent Code Updates

If you are releasing frequent updates or changes to infrastructure code, you need to be sure you haven’t introduced vulnerabilities.

Our Approach

OpenZeppelin’s tailored and targeted infrastructure security

Elite Expertise First

Every review is led by veteran researchers who live and breathe blockchain infrastructure.

We Know Where to Look

Building on our expertise, we identify and focus on specific components and modules where exploits are most likely to occur.

Risk-Weighted Scoping

Each component is graded for criticality and complexity, so time and budget go toward business-critical logic, not low-impact boilerplate.

Our Infrastructure Security Researchers have deep expertise in various languages and technologies.

The Solutions

Security
Assessments & Audits

We only do what is needed to make your infrastructure safe, ensuring clients' projects remain secure without breaking their budgets.

Step 1
Security Assessment

Identify high-level flaws, architectural problems, and the most critical areas a subsequent audit should focus on. Ideal for projects in late-development stages or with very large codebases. Though an assessment is not an audit engagement, it can be critical to identify and strengthen key areas before moving on to an audit.

Step 2
Security Audit

A deep, comprehensive code review to uncover security issues and provide recommendations for safe deployment. Usually performed in different phases on multiple subscopes, previously identified during the Security Assessment.
