# Slither, the Solidity source analyzer Logo [![Build Status](https://img.shields.io/github/actions/workflow/status/crytic/slither/ci.yml?branch=master)](https://github.com/crytic/slither/actions?query=workflow%3ACI) [![Slack Status](https://empireslacking.herokuapp.com/badge.svg)](https://empireslacking.herokuapp.com) [![PyPI version](https://badge.fury.io/py/slither-analyzer.svg)](https://badge.fury.io/py/slither-analyzer) Slither is a Solidity static analysis framework written in Python3. It runs a suite of vulnerability detectors, prints visual information about contract details, and provides an API to easily write custom analyses. Slither enables developers to find vulnerabilities, enhance their code comprehension, and quickly prototype custom analyses. - [Features](#features) - [Usage](#usage) - [How to Install](#how-to-install) - [Detectors](#detectors) - [Printers](#printers) - [Tools](#tools) - [API Documentation](#api-documentation) - [Getting Help](#getting-help) - [FAQ](#faq) - [Publications](#publications) ## Features - Detects vulnerable Solidity code with low false positives (see the list of [trophies](./trophies.md)) - Identifies where the error condition occurs in the source code - Easily integrates into continuous integration and Hardhat/Foundry builds - Built-in 'printers' quickly report crucial contract information - Detector API to write custom analyses in Python - Ability to analyze contracts written with Solidity >= 0.4 - Intermediate representation ([SlithIR](https://github.com/trailofbits/slither/wiki/SlithIR)) enables simple, high-precision analyses - Correctly parses 99.9% of all public Solidity code - Average execution time of less than 1 second per contract - Integrates with Github's code scanning in [CI](https://github.com/marketplace/actions/slither-action) ## Usage Run Slither on a Hardhat/Foundry/Dapp/Brownie application: ```bash slither . ``` This is the preferred option if your project has dependencies as Slither relies on the underlying compilation framework to compile source code. However, you can run Slither on a single file that does not import dependencies: ```bash slither tests/uninitialized.sol ``` ## How to install Slither requires Python 3.8+. If you're **not** going to use one of the [supported compilation frameworks](https://github.com/crytic/crytic-compile), you need [solc](https://github.com/ethereum/solidity/), the Solidity compiler; we recommend using [solc-select](https://github.com/crytic/solc-select) to conveniently switch between solc versions. ### Using Pip ```bash pip3 install slither-analyzer ``` ### Using Git ```bash git clone https://github.com/crytic/slither.git && cd slither python3 setup.py install ``` We recommend using a Python virtual environment, as detailed in the [Developer Installation Instructions](https://github.com/trailofbits/slither/wiki/Developer-installation), if you prefer to install Slither via git. ### Using Docker Use the [`eth-security-toolbox`](https://github.com/trailofbits/eth-security-toolbox/) docker image. It includes all of our security tools and every major version of Solidity in a single image. `/home/share` will be mounted to `/share` in the container. ```bash docker pull trailofbits/eth-security-toolbox ``` To share a directory in the container: ```bash docker run -it -v /home/share:/share trailofbits/eth-security-toolbox ``` ### Integration - For GitHub action integration, use [slither-action](https://github.com/marketplace/actions/slither-action). - To generate a Markdown report, use `slither [target] --checklist`. - To generate a Markdown with GitHub source code highlighting, use `slither [target] --checklist --markdown-root https://github.com/ORG/REPO/blob/COMMIT/` (replace `ORG`, `REPO`, `COMMIT`) ## Detectors Num | Detector | What it Detects |

[Contact us](https://www.trailofbits.com/contact/) to get help on building custom tools. ## API Documentation Documentation on Slither's internals is available [here](https://crytic.github.io/slither/slither.html). ## Getting Help Feel free to stop by our [Slack channel](https://empireslacking.herokuapp.com) (#ethereum) for help using or extending Slither. - The [Printer documentation](https://github.com/trailofbits/slither/wiki/Printer-documentation) describes the information Slither is capable of visualizing for each contract. - The [Detector documentation](https://github.com/trailofbits/slither/wiki/Adding-a-new-detector) describes how to write a new vulnerability analyses. - The [API documentation](https://github.com/crytic/slither/wiki/Python-API) describes the methods and objects available for custom analyses. - The [SlithIR documentation](https://github.com/trailofbits/slither/wiki/SlithIR) describes the SlithIR intermediate representation. ## FAQ How do I exclude mocks or tests? - View our documentation on [path filtering](https://github.com/crytic/slither/wiki/Usage#path-filtering). How do I fix "unknown file" or compilation issues? - Because slither requires the solc AST, it must have all dependencies available. If a contract has dependencies, `slither contract.sol` will fail. Instead, use `slither .` in the parent directory of `contracts/` (you should see `contracts/` when you run `ls`). If you have a `node_modules/` folder, it must be in the same directory as `contracts/`. To verify that this issue is related to slither, run the compilation command for the framework you are using e.g `npx hardhat compile`. That must work successfully; otherwise, slither's compilation engine, crytic-compile, cannot generate the AST. ## License Slither is licensed and distributed under the AGPLv3 license.
