We are interested in exploring various security, privacy, and usability aspects of current blockchain ecosystem. Our current efforts include, but not limited to, developing static and dynamic analysis tools for smart contract auditing and verification, providing security solutions for better trading exchanges protection and enhanced wallet experiences, as well as performing large-scale data analysis and investigation of blockchain-wide events (or anomalies). We are closely collaborating with our clientele and partners while being committed to responsibly reporting our discoveries to public or affected vendors for timely fixes.
