Solidity is evolving rapidly

We aim for a regular (non-breaking) release every month, with approximately one breaking release per year. You can follow the implementation status of new features in the Solidity GitHub project.

Get started

Contribute to Solidity

Solidity continues to improve with help from our global community. Check out these ways to get involved and contribute to the Solidity project.

Reporting issues and vulnerabilities


To report an issue, please use the GitHub issues tracker. To report a vulnerability, please check out the instructions in the SECURITY.md.

Translating the documentation


Translations help developers from all corners of the world to be able to read the documentation and learn Solidity.

Fixing and responding to issues


Fixing and responding to issues, especially those tagged as “good first issue”, is a great way to get started for external contributors.

Contributing to language design


We welcome Solidity power users, auditors, security experts and tooling developers to get involved in the Solidity language design process. Join the Solidity forum, where existing properties of the language and proposals for new language features can be discussed.
