Solidity

soliditylang.org

Contract-oriented language for writing smart contracts on Ethereum and EVM chains.

Overview

Solidity is a statically-typed, curly-braces programming language designed specifically for writing smart contracts that run on the Ethereum Virtual Machine. It enables developers to define the rules and behavior of decentralized applications (DApps), including tokens, ownership systems, voting mechanisms, and other blockchain-based logic.

The language is open-source and community-driven, governed by a core team now part of the Argot Collective. Solidity follows a regular release cycle with non-breaking releases approximately monthly and breaking releases roughly annually. The project actively welcomes contributions from developers, auditors, security experts, and tooling developers worldwide.

Use this if
You are building smart contracts on Ethereum, developing decentralized applications, or need a language specifically designed for blockchain logic and token implementation.
Skip this if
You need a general-purpose programming language, are targeting non-Ethereum blockchains, or prefer languages with simpler learning curves for beginners.
