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.\n\n* [Features](#features)\n* [Usage](#usage)\n* [How to install](#how-to-install)\n  * [Using Pip](#using-pip)\n  * [Using Git](#using-git)\n  * [Using Docker](#using-docker)\n  * [Integration](#integration)\n* [Detectors](#detectors)\n* [Printers](#printers)\n  * [Quick Review Printers](#quick-review-printers)\n  * [In-Depth Review Printers](#in-depth-review-printers)\n* [Tools](#tools)\n* [API Documentation](#api-documentation)\n* [Getting Help](#getting-help)\n* [FAQ](#faq)\n* [License](#license)\n* [Publications](#publications)\n  * [Trail of Bits publication](#trail-of-bits-publication)\n  * [External publications](#external-publications)\n\n## Features\n\n* Detects vulnerable Solidity code with low false positives (see the list of [trophies](./trophies.md))\n* Identifies where the error condition occurs in the source code\n* Easily integrates into continuous integration and Hardhat/Foundry builds\n* Built-in 'printers' quickly report crucial contract information\n* Detector API to write custom analyses in Python\n* Ability to analyze contracts written with Solidity \u003e= 0.4\n* Intermediate representation ([SlithIR](https://github.com/crytic/slither/wiki/SlithIR)) enables simple, high-precision analyses\n* Correctly parses 99.9% of all public Solidity code\n* Average execution time of less than 1 second per contract\n* Integrates with Github's code scanning in [CI](https://github.com/marketplace/actions/slither-action)\n* Support for Vyper smart contracts\n\n## Usage\n\nRun Slither on a Hardhat/Foundry/Dapp/Brownie application:\n\n```console\nslither .\n```\n\nThis is the preferred option if your project has dependencies as Slither relies on the underlying compilation framework to compile source code.\n\nHowever, you can run Slither on a single file that does not import dependencies:\n\n```console\nslither tests/uninitialized.sol\n```\n\n## How to install\n\n\u003e **Note** \u003cbr /\u003e\n\u003e Slither requires Python 3.8+.\nIf 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.\n\n### Using Pip\n\n```console\npython3 -m pip install slither-analyzer\n```\n\n#### How to upgrade\n\n```console\npython3 -m pip install --upgrade slither-analyzer\n```\n\n### Using Brew\n\n```console\nbrew install slither-analyzer\n```\n\n### Using Git\n\n```bash\ngit clone https://github.com/crytic/slither.git \u0026\u0026 cd slither\npython3 -m pip install .\n```\n\nWe recommend using a Python virtual environment, as detailed in the [Developer Installation Instructions](https://github.com/crytic/slither/wiki/Developer-installation), if you prefer to install Slither via git.\n\n### Using Docker\n\nUse the [`eth-security-toolbox`](https://github.com/crytic/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.\n\n```bash\ndocker pull trailofbits/eth-security-toolbox\n```\n\nTo share a directory in the container:\n\n```bash\ndocker run -it -v /home/share:/share trailofbits/eth-security-toolbox\n```\n\n### Integration\n\n* For GitHub action integration, use [slither-action](https://github.com/marketplace/actions/slither-action).\n* For pre-commit integration, use (replace `$GIT_TAG` with real tag)\n  ```YAML\n  - repo: https://github.com/crytic/slither\n    rev: $GIT_TAG\n    hooks:\n      - id: slither\n  ```\n* To generate a Markdown report, use `slither [target] --checklist`.\n* 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`)\n\n## Detectors\n\nNum | Detector | What it

To verify that this issue is related to slither,\nrun the compilation command for the framework you are using e.g `npx hardhat compile`. That must work successfully;\notherwise, slither's compilation engine, crytic-compile, cannot generate the AST.\n\n## License\n\nSlither is licensed and distributed under the AGPLv3 license.
