On November 10, 2024, a bug in the Solidity code generator was found by @Audittens. The bug was initially reported to affect deletion and partial assignment operations on fixed-length storage arrays that cross the 2**256-slot boundary. Two instances were reported: one in the IR pipeline and one in the evmasm pipeline. During our further investigation, we discovered a third instance affecting copying from arrays placed at the storage boundary. The effect of the bug is that such storage cleanup or copy operations may not...

The 2025 edition of the Solidity Summit took place in Buenos Aires during Devconnect, gathering around 350 participants from across the ecosystem. The event brought together language designers and compiler engineers - but also tooling authors, security experts, educators, and long-time Solidity power users. Attendees had the chance to get up to speed with the latest language proposals and new features, hear updates from the ecosystem, and learn from teams building on Solidity at scale. A central message from the Solidity...

Solidity is the most widely used smart contract language. It is robust, trustworthy, and today secures hundreds of billions of dollars of value. We are proud of this success, and its track record of secure code generation. Users of Solidity will however be keenly aware of some of its limitations. The type system often lacks the expressiveness to produce reusable library code or enforce core safety properties. The language has very limited support for compile time evaluation. Many features are implemented in an inconsistent manner,...

The Road to Core Solidity Solidity has just reached its 10-year mark. This is a perfect opportunity for us to present "The Road to Core Solidity", a series of blog posts through which we share where we are headed with the language. In this series we want to show the community how we see the project's roadmap in the long run. While we are quite confident about its general direction, many details are not set in stone. It is as much a presentation of what...

We are thrilled to share the Solidity Developer Survey 2024 results with you! In this blog post, we will be going over key insights and a detailed analysis of the various sections of the survey. Before diving in, we would like to thank everyone who submitted a response to the survey and helped us reach the right audience for it. Your inputs are invaluable to us and are pivotal in driving important language design decisions and improving Solidity as an open-source...

The EVM Object Format is a long awaited upgrade that modernizes the EVM and removes obstacles that have wide-ranging effects on the entire language, tooling and application ecosystem on Ethereum. Solidity is in full support of the proposal and in this post we would like to explain why. We will address the benefits it brings and the reasons why alternatives proposed so far fall short of achieving its goals. Benefits of EOF Tooling Development tooling is the area where the benefits of EOF are the most evident. The biggest...

We are excited to announce the release of the Solidity Compiler v0.8.29. This latest version of the compiler brings experimental support for EVM Object Format, support for custom storage layouts, initial supoort for ethdebug, and more! Notable Features Experimental Support for EVM Object Format 0.8.29 brings us experimental support for EVM Object Format (EOF). Please note that the feature can only be enabled when compiling for the Osaka EVM version, which has not yet been deployed to mainnet or testnets. The experimental backend is still incomplete...
