Don't miss anything.

The SWC Registry is a community catalog of known smart contract vulnerabilities with detailed descriptions, code samples and remediations. MythX uses the SWC Registry as its database when scanning code for security issues.

  • We'll handle it.

    MythX uses its own servers to process your analysis quickly while maximizing security.

      • Scalability

      • Easily access scalable, powerful, parallel security analysis with just a lightweight plugin.

      • Relevance

      • Your code is always analyzed against the latest version of the SWC Registry, which we continually update.

      • Speed

      • MythX always returns analysis results faster than your local machine: as little as 90 seconds in Quick Mode.
