**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.
* 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
```console
slither .
```

However, you can run Slither on a single file that does not import dependencies:
```bash
```console
slither tests/uninitialized.sol
```
## How to install
Slither requires Python 3.8+.

> 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

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.
* 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,
