How we audit

Review the documentation

Reviewing your organization's cloud infrastructure, including servers, networks, and storage, as well as the architecture of the systems and how they are configured

Understand the consensus

Understand the consensus mechanism used by the blockchain protocol. This will help to identify any potential weaknesses in the mechanism that could be exploited

Perform code review

Perform a thorough code review of the blockchain protocol, looking for potential vulnerabilities, such as buffer overflow, SQL injection, and other common software vulnerabilities

Test the code

Use automated testing tools to test the code for potential vulnerabilities. This includes unit testing, integration testing, and regression testing

Perform penetration testing

Perform penetration testing to simulate a real-world attack on the blockchain protocol. This includes trying to exploit vulnerabilities identified during the code review and testing

Evaluate compliance

Evaluate the blockchain protocol for compliance with relevant regulations and industry standards

Interoperability testing

Evaluate the blockchain protocol's compatibility with other blockchain networks and systems, ensuring that the protocol can interact with other systems in the ecosystem

Performance testing

Evaluate the blockchain protocol's performance, including its scalability, gas consumption, and usability


Create a detailed report of the audit findings, including any vulnerabilities or issues identified, and recommendations for addressing them

Provide remediation support

Provide assistance with addressing any issues or vulnerabilities identified during the audit, including guidance on how to remediate the issues
