Smart Contract Fuzzing simulates millions of randomized and targeted transactions probing your system for critical flaws.
In every engagement, Guardian fuzzing engineers construct a comprehensive stateful fuzzing suite for your Smart Contract system.
This is how Guardian sees around corners and uncovers vulnerabilities invisible to the naked eye.
Additionally, your fuzzing suite continues to provide continuous security coverage even after your Guardian engagement.
“During our audit of Limit, Guardian did 100s of millions of runs, which is insane when you think about that many unique combinations of inputs.”

“Guardian’s comprehensive fuzz testing suite has been a huge help in getting launch-ready, providing us robust test coverage we continue to build upon ourselves.”
