"Our audit with Guardian way exceeded expectations in terms of the number of vulnerabilities they were able to find and the level of service that they provided. Their two-team approach led to a high number of findings, much more than even our prior audit for the same contract."

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.”

All remediations are reviewed by both teams independently and fuzzed thoroughly to ensure issues are fully patched and no new issues arise.
