Solhint

Solhint is an open-source JavaScript command-line tool that lints Solidity code and applies documented style-guide and security-related validations. It supports project configuration through `.solhint.json`, multiple configuration levels, plugins, ignored paths, caching, automatic fixes for selected rules and several report formats.

Understand the project

Practical overview

When it fits

Use Solhint when a Solidity project needs a repeatable command-line check for source-level style and security-related rules, including before deployment as one part of a broader development workflow.

Who it is for

  • Solidity developers
  • Ethereum smart-contract teams
  • Projects adding source-level code-quality checks to a developer toolchain

Documented uses

  • Lint one Solidity file or a group of files matched by a glob.
  • Initialize and maintain Solidity linting configuration.
  • Check selected style and security-related rules before later development or deployment steps.
  • Save or format lint reports for downstream tooling.
Before you choose

Requirements & limits

The project is publicly accessible on GitHub and is described as open source under the MIT license. The documented installation uses npm and the command-line interface.

  • Solhint runs as a CLI and requires an npm-based installation path.
  • Rules can be initialized from the recommended configuration and adjusted through .solhint.json.
  • Multiple configuration files can apply across project directories, with the closest applicable rules taking precedence.
  • Plugins are supported, including configured plugin paths for environments such as editor integrations.
  • Automatic fixing is limited to the rules listed in the project documentation.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up Solhint for a Solidity project

Install Solhint, create its initial configuration and lint Solidity files.

Before you start

  • npm
  • A Solidity project or Solidity source files

Steps

  1. Install Solhint with npm using the documented global installation command.

  2. Run the version option to verify the command is available.

  3. Run solhint --init to create a .solhint.json configuration with recommended rules.

  4. Run Solhint against one Solidity file or a glob covering the project files.

Expected outcome

The project has an initialized Solhint configuration and a lint report for the selected Solidity source.

Guide limitations

  • The documented setup does not establish deployment checks or broader contract assurance.
  • Automatic fixes apply only to the listed supported rules.
