The Solidity Contract-Oriented Programming Language

Join the chat at https://gitter.im/ethereum/solidity

Solidity is a statically typed, contract-oriented, high-level language for implementing smart contracts on the Ethereum platform.

Table of Contents

Background

Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on the Ethereum Virtual Machine. Smart contracts are programs that are executed inside a peer-to-peer network where nobody has special authority over the execution, and thus they allow to implement tokens of value, ownership, voting and other kinds of logics.

When deploying contracts, you should use the latest released version of Solidity. This is because breaking changes as well as new features and bug fixes are introduced regularly. We currently use a 0.x version number to indicate this fast pace of change.

Build and Install

Instructions about how to build and install the Solidity compiler can be found in the Solidity documentation.

Example

A "Hello World" program in Solidity is of even less use than in other languages, but still:

pragma solidity ^0.5.0;

contract HelloWorld {
  function helloWorld() external pure returns (string memory) {
    return "Hello, World!";
  }
}

To get started with Solidity, you can use Remix, which is an browser-based IDE. Here are some example contracts:

  1. Voting
  2. Blind Auction
  3. Safe remote purchase
  4. Micropayment Channel

Documentation

Development

Solidity is still under development. Contributions are always welcome! Please follow the Developers Guide if you want to help.
