"Guardian is one of the best auditors we have worked with so far. Paying per vulnerability helps ensure that goals are aligned and we wish this format was more widely adopted. Contract code was thoroughly vetted with high quality reports including detailed recommendations and working proof of concept tests to demonstrate issues."

"As a security audit company, Guardian's approach to security and overall effectiveness is truly exceptional. Working with them has been a revelation – their auditors are among the best we've ever collaborated with. Their swift and clear communication is a testament to their commitment, and their unparalleled domain expertise in DeFi, especially derivatives, sets them apart."

"The Guardian team’s attention to detail is top-notch. Sometimes when you get an audit done, you wonder how closely the team looked at your code and considered all surface area for attacks. We sleep soundly at night knowing that Guardian went through every detail of our codebase rigorously."
