What is it?

Solidity is a curly-brace, statically-typed language designed for smart contracts that run on the Ethereum Virtual Machine. Smart contracts are programs executed on a peer-to-peer network with no single party in control, which makes them suitable for tokens, ownership records, voting, and other logic that needs to run without a trusted intermediary.

This repository contains the Solidity compiler, which is the reference implementation of the language, written in C++. The project is maintained by a core team under the Argot Collective and is still in its 0.x version series, with breaking changes and new features introduced regularly, so the latest released version is recommended for deployments.

Developers typically write contracts in an editor or use the browser-based Remix IDE, and the documentation hosted on the Solidity Language Portal covers building the compiler from source and includes example contracts such as voting, blind auctions, and micropayment channels.

Key features

  • 01Statically-typed, contract-oriented syntax with a curly-brace style
  • 02Compiles to bytecode for the Ethereum Virtual Machine
  • 03Reference compiler implemented in C++
  • 04Official documentation and example contracts are available

Use cases

  • Writing token contracts or ownership registries on Ethereum
  • Building on-chain voting or auction applications
  • Learning how smart contract languages are designed and compiled

Quick start

  1. 1

    Read the build instructions in the Solidity documentation

  2. 2

    Try the language in the browser using Remix IDE

Things to know

  • Licensed under GPL-3.0, a copyleft license that requires derivative works to be open source under the same terms.
  • The README gives no direct install command, so you must build the compiler from source following external docs.
  • The project is version 0.x and introduces breaking changes regularly, so use the latest release.
