Solidity is a statically-typed, curly-braces programming language purpose-built for writing smart contracts that run on the Ethereum blockchain. As one of the most widely adopted languages in decentralized application (dApp) development, Solidity empowers developers to create secure, transparent, and self-executing contracts that power everything from DeFi protocols to NFT marketplaces.
With Ethereum continuing to evolve through upgrades like Pectra and innovations such as EOF (EVM Object Format), Solidity remains at the forefront of blockchain programming—constantly adapting to new standards, security requirements, and developer needs.
Solidity’s Rapid Evolution and Release Cycle
The Solidity team follows a structured and predictable release schedule to ensure steady progress without compromising stability. A new non-breaking version is released approximately every month, allowing developers to access incremental improvements, bug fixes, and minor feature additions.
In contrast, major breaking changes are rolled out about once per year. This approach balances innovation with reliability—giving teams enough time to adapt while ensuring the language keeps pace with Ethereum’s development roadmap.
You can track upcoming features and enhancements in real-time via the Solidity GitHub project board, where proposals, implementation status, and community feedback are openly shared. This transparency fosters trust and collaboration across the global developer ecosystem.

Ways to Contribute to the Solidity Project
Solidity thrives thanks to its vibrant open-source community. Whether you're a beginner or an experienced developer, there are multiple ways to get involved:
1. Report Issues and Vulnerabilities
If you encounter bugs or potential security flaws, use the GitHub Issues Tracker to report them. For sensitive vulnerabilities, follow the guidelines outlined in SECURITY.md, which ensures responsible disclosure.
2. Help Translate Documentation
Making Solidity accessible worldwide is a key goal. By translating documentation into different languages, contributors help non-English speakers learn the language more effectively and participate in the ecosystem.
3. Fix Bugs and Respond to Issues
Beginner-friendly tasks are often tagged as “good first issue” on GitHub. Tackling these helps new contributors gain experience while directly improving the codebase.
4. Shape the Future of Language Design
Experienced developers, auditors, and tooling engineers are encouraged to join the Solidity Forum—the central hub for discussing language improvements, reviewing proposals (EIPs), and influencing future versions of Solidity.
Stay Updated with the Latest Developments
To keep up with changes, enhancements, and community insights, follow the Solidity Blog. Recent highlights include:
🔹 Solidity 0.8.30 Release (May 7, 2025)
This maintenance release aligns with the Pectra Ethereum network upgrade, shifting the default EVM version from Cancun to Prague. Pectra introduces critical updates across both execution and consensus layers, enhancing scalability and developer experience.
Key EIPs implemented support new opcodes and optimizations that improve contract deployment efficiency and runtime performance.
🔹 Solidity Developer Survey 2024 Results
Published in April 2025, this comprehensive report analyzes feedback from thousands of developers worldwide. Insights cover preferred tooling, common pain points, adoption trends, and expectations for future features—guiding roadmap decisions and usability improvements.
🔹 The Case for EOF: Modernizing the EVM
EOF (EVM Object Format) represents a foundational upgrade aimed at modernizing the Ethereum Virtual Machine. It introduces structural improvements that simplify verification, enable better optimization, and pave the way for future innovations.
Solidity fully supports EOF due to its benefits in:
- Tooling: Clearer separation between code and data improves debugging and analysis.
- Security: Enhanced validation reduces risks of malformed contracts.
- Efficiency: More predictable gas costs and streamlined deployment processes.
Try Solidity in the Playground
Experiment with Solidity directly in your browser using the built-in compiler playground. While limited in scope, it's ideal for testing small snippets and learning syntax basics.
For full-featured development, switch to Remix IDE—a powerful, web-based environment offering debugging, testing, and deployment tools tailored for smart contract workflows.
Current compiler output shows:
- Bytecode size: 0 bytes (empty contract)
- Estimated deployment cost: gas variable depending on complexity
- Assembly-level inspection available for advanced users
Upcoming and Past Solidity Events
Community engagement plays a vital role in shaping Solidity’s direction. Notable past events include:
- Solidity Summit 2023 – Held in Istanbul, Turkey
- Underhanded Solidity Contest 2022 – Remote competition highlighting security pitfalls
- Solidity Summit 2022 & 2020 – In-person and virtual gatherings for core contributors
Future summits will continue to bring together developers, researchers, and ecosystem leaders to discuss advancements and challenges.
Frequently Asked Questions (FAQ)
Q: What is Solidity used for?
A: Solidity is primarily used to write smart contracts on Ethereum and other EVM-compatible blockchains. These contracts automate agreements without intermediaries and power applications in DeFi, NFTs, DAOs, and more.
Q: Is Solidity hard to learn?
A: Developers familiar with JavaScript or C++ will find Solidity’s syntax intuitive. However, unique concepts like gas optimization, reentrancy attacks, and immutable deployments require careful study.
Q: How often are breaking changes introduced?
A: Major breaking releases occur roughly once per year. Regular monthly updates include non-breaking improvements, ensuring backward compatibility for most projects.
Q: Can I use Solidity on blockchains other than Ethereum?
A: Yes! Solidity works on any EVM-compatible chain such as Binance Smart Chain, Polygon, Arbitrum, Optimism, and Avalanche.
Q: Where can I find learning resources for Solidity?
A: The official Solidity documentation is comprehensive. Additional resources include freeCodeCamp tutorials, CryptoZombies interactive course, and GitHub examples.
Q: Why is EOF important for Solidity’s future?
A: EOF improves contract structure by clearly separating code from data, enabling better tooling support, enhanced verification, and long-term extensibility of the EVM.
