Solidity is a statically typed, contract-oriented, high-level language for implementing smart contracts on the Ethereum platform.
|
||
|
||
For a good overview and starting point, please check out the official [Solidity Language Portal](https://soliditylang.org).

## 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 anyone to implement tokens of value,
|
||
ownership, voting, and other kinds of logic.
|
||
|
||
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](https://semver.org/#spec-item-4).
|
||
|
||
## Build and Install
|
||
|
||
Instructions about how to build and install the Solidity compiler can be
|
||
found in the [Solidity documentation](https://docs.soliditylang.org/en/latest/installing-solidity.html#building-from-source).
|
||
|
||
|
||
## Example
|
||
|
||
A "Hello World" program in Solidity is of even less use than in other languages, but still:
|
||
|
||
```solidity
|
||
// SPDX-License-Identifier: MIT
|
||
pragma solidity >=0.6.0 <0.9.0;
|
||
|
||
contract HelloWorld {
|
||
function helloWorld() external pure returns (string memory) {
|
||
return "Hello, World!";
|
||
}
|
||
}
|
||
```
|
||
|
||
To get started with Solidity, you can use [Remix](https://remix.ethereum.org/), which is a
|
||
browser-based IDE. Here are some example contracts:
|
||
|
||
1. [Voting](https://docs.soliditylang.org/en/latest/solidity-by-example.html#voting)
|
||
2. [Blind Auction](https://docs.soliditylang.org/en/latest/solidity-by-example.html#blind-auction)
|
||
3. [Safe remote purchase](https://docs.soliditylang.org/en/latest/solidity-by-example.html#safe-remote-purchase)
|
||
4. [Micropayment Channel](https://docs.soliditylang.org/en/latest/solidity-by-example.html#micropayment-channel)
|
||
|
||
## Documentation
|
||
|
||
The Solidity documentation is hosted at [Read the docs](https://docs.soliditylang.org).
|
||
|
||
## Development
|
||
|
||
Solidity is still under development. Contributions are always welcome!
|
||
Please follow the
|
||
[Developers Guide](https://docs.soliditylang.org/en/latest/contributing.html)
|
||
if you want to help.
|
||
|
||
You can find our current feature and bug priorities for forthcoming
|
||
releases in the [projects section](https://github.com/ethereum/solidity/projects).
