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) * [Using Pip](#using-pip) * [Using Git](#using-git) * [Using Docker](#using-docker) * [Integration](#integration) * [Detectors](#detectors) * [Printers](#printers) * [Quick Review Printers](#quick-review-printers) * [In-Depth Review Printers](#in-depth-review-printers) * [Tools](#tools) * [API Documentation](#api-documentation) * [Getting Help](#getting-help) * [FAQ](#faq) * [License](#license) * [Publications](#publications) * [Trail of Bits publication](#trail-of-bits-publication) * [External publications](#external-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) * Support for Vyper smart contracts ## Usage Run Slither on a Hardhat/Foundry/Dapp/Brownie application: ```console 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: ```console slither tests/uninitialized.sol ``` ## How to install > **Note**
> 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 ```console python3 -m pip install slither-analyzer ``` ### Using Git ```bash git clone https://github.com/crytic/slither.git && cd slither python3 -m pip 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). * For pre-commit integratio, use (replace `$GIT_TAG` with real tag) ``` - repo: https://github.com/crytic/slither rev: $GIT_TAG hooks: - slither ``` * 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 | Impact | Confidence --- |

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.
