Solidity v0.8.17 is here! 🎉

Solidity 0.8.17 fixes an important bug, makes overflow checks on multiplication more efficient and adds an LSP feature to always analyze all files in a project.

For all details please refer to the release announcement. For details on the bugs, see the security alert post on Storage Write Removal Bug On Conditional Early Termination.

Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum.

Solidity is evolving rapidly.

As a relatively young language, Solidity is advancing at a rapid speed. We aim for a regular (non-breaking) release every 2-3 weeks, with approximately two breaking releases per year. You can follow the implementation status of new features in the Solidity Github project. 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.

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

New to Solidity? Getting started is easy.

As a beginner, you find great tutorials, resources and tools that help you get started building with Solidity on the ethereum.org developer portal.

Alternatively, you can start by learning the basics about blockchain, smart contracts and the Ethereum Virtual Machine (EVM) in the Solidity docs.

Contribute towards enhancing Solidity by sharing your opinion in the language design discussions!


We welcome Solidity power users, auditors, security experts and tooling developers to get involved and actively contribute to the Solidity language design process.

  • Join the Solidity forum, where existing properties of the language and proposals for new language features can be discussed.

  • Give input by completing (feature) feedback surveys which are regularly distributed via Twitter and the forum.

  • Join the dedicated language design discussion calls, in which selected topics, issues or feature implementations are debated in detail.

  • Or share your thoughts and take part in design discussions directly via relevant Github issues.

For ad-hoc inquiries and questions you can reach out to the core team using the solidity-dev Matrix channel (currently also still available on Gitter), a dedicated chatroom for conversations around the Solidity compiler and language development.

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

After a first virtual Solidity Summit in 2020, we met in person for the second Solidity Summit in 2022 in Amsterdam.

Solidity Summits usually feature talks & discussions on Solidity, Yul, language design and tooling. The event series aims to...

  • Enable useful (language-design related) discussions which result in improvement proposals and actual implementations.

  • Foster communication between teams working on similar topics.

  • Identify needs for the smart contract ecosystem for Ethereum.
