Mythril is a security analysis tool for EVM bytecode. It detects security vulnerabilities in smart contracts built for Ethereum, Hedera, Quorum, Vechain, Roostock, Tron and other EVM-compatible blockchains. It uses symbolic execution, SMT solving and taint analysis to detect a variety of security vulnerabilities. It's also used (in combination with other tools and techniques) in the [MythX](https://mythx.io) security analysis platform.
If you are a smart contract developer, we recommend using [MythX tools](https://github.com/b-mueller/awesome-mythx-smart-contract-security-tools) which are optimized for usability and cover a wider range of security issues.
Whether you want to contribute, need support, or want to learn what we have cooking for the future, our [Discord server](https://discord.gg/E3YrVtG) will serve your needs.
## Installation and setup
Get it with [Docker](https://www.docker.com):
```bash
$ docker pull mythril/myth
```
Install from Pypi:
```bash
$ pip3 install mythril
```
See the [docs](https://mythril-classic.readthedocs.io/en/master/installation.html) for more detailed instructions.
## Usage
Run:
```
$ myth analyze
```
Or:
```
$ myth analyze -a
```
Specify the maximum number of transaction to explore with `-t `. You can also set a timeout with `--execution-timeout `. Example ([source code](https://gist.github.com/b-mueller/2b251297ce88aa7628680f50f177a81a#file-killbilly-sol)):
```
> myth a killbilly.sol -t 3
==== Unprotected Selfdestruct ====
SWC ID: 106
Severity: High
Contract: KillBilly
Function name: commencekilling()
PC address: 354
Estimated Gas Usage: 574 - 999
The contract can be killed by anyone.
Anyone can kill this contract and withdraw its balance to an arbitrary address.

Instructions for using Mythril are found on the [docs](https://mythril-classic.readthedocs.io/en/master/).
For support or general discussions please join the Mythril community on [Discord](https://discord.gg/E3YrVtG).
## Building the Documentation
Mythril's documentation is contained in the `docs` folder and is published to [Read the Docs](https://mythril-classic.readthedocs.io/en/develop/). 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`.
## Vulnerability Remediation
Visit the [Smart Contract Vulnerability Classification Registry](https://swcregistry.io/) to find detailed information and remediation guidance for the vulnerabilities reported.
