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.

Stay Updated

Stay always up-to-date by following the Solidity blog.

You can see the upcoming changes for the next breaking release by switching from the default branch (develop) to the breaking branch. You can actively shape Solidity by providing your input and participating in the language design in the Solidity forumand participating in the yearly Solidity developer surveys.

Solidity 0.8.21 Release Announcement

Posted by Solidity Team on July 19, 2023

We are excited to announce the latest release of the Solidity Compiler, Solidity v0.8.21. Notable New Features Stack-to-memory mover always enabled via-IR The release addresses the issue of unoptimized code produced by the IR-based code generation pipeline being overly prone to "Stack Too Deep" errors. This is meant to help tools such as debuggers, which lose much of their effectiveness when working with optimized code. The legacy pipeline can often avoid running out of reachable stack slots even in unoptimized mode, but this comes at...

Bug in Legacy Code Generation When Accessing the .selector Member on Expressions with Side Effects

Posted by Solidity Team on July 19, 2023

On June 26, 2023, a bug in the legacy code generation pipeline of the Solidity compiler was found during investigation of a security report related to the use of abi.decode with a ternary expression that has side effects, as the type argument. The legacy code generator was not evaluating complex expressions, like assignments, function calls, or conditionals, whose .selector was being accessed. This led to the side-effects of such expressions not being executed, and therefore potentially incorrect behavior of contracts compiled using the legacy pipeline. The...

Solidity Events

The Solidity Summit is a free interactive forum for people involved and interested in the Solidity language and the ecosystem around it.

Its goal is to enable useful (language-design related) discussions which result in improvement proposals and actual implementations, foster communication between teams working on similar topics and to identify needs for the smart contract ecosystem for Ethereum.
