Mythril Classic is an open-source security analysis tool for Ethereum smart contracts. It uses symbolic analysis, taint analysis and control flow checking to detect a variety of security vulnerabilities.

Note that Mythril Classic is designed for security auditors. If you are a smart contract developer, we recommend using MythX tools which are optimized for usability and cover a wider range of security issues:

• Sabre
• MythX Plugin for Truffle

Whether you want to contribute, need support, or want to learn what we have cooking for the future, our Discord server will serve your needs.

Get it with Docker:

$ docker pull mythril/myth

Install from Pypi:

$ pip3 install mythril

See the Wiki for more detailed instructions.

Instructions for using Mythril Classic are found on the Wiki.

Mythril Classic's documentation is contained in the docs folder and is published to Read the Docs. It is based on Sphinx and can be built using the Makefile contained in the subdirectory:

cd docs
make html

This will create a build output directory containing the HTML output. Alternatively, PDF documentation can be built with make latexpdf. The available output format options can be seen with make help.

Visit the Smart Contract Vulnerability Classification Registry to find detailed information and remediation guidance for the vulnerabilities reported.
