|
|
Solidity is an object-oriented, high-level language for implementing smart
|
|
contracts. Smart contracts are programs which govern the behaviour of accounts
|
|
within the Ethereum state.
|
|
|
|
Solidity was influenced by C++, Python and JavaScript and is designed to target
|
|
the Ethereum Virtual Machine (EVM).
|
|
|
|
Solidity is statically typed, supports inheritance, libraries and complex
|
|
user-defined types among other features.
|
|
|
|
With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions,
|
|
and multi-signature wallets.

Language Documentation
|
|
----------------------
|
|
|
|
If you are new to the concept of smart contracts we recommend you start with
|
|
:ref:`an example smart contract <simple-smart-contract>` written
|
|
in Solidity. When you are ready for more detail, we recommend you read the
|
|
:doc:`"Solidity by Example" <solidity-by-example>` and :doc:`"Solidity in Depth" <solidity-in-depth>` sections to learn the core concepts of the language.
|
|
|
|
For further reading, try :ref:`the basics of blockchains <blockchain-basics>`
|
|
and details of the :ref:`Ethereum Virtual Machine <the-ethereum-virtual-machine>`.
|
|
|
|
.. hint::
|
|
You can always try out code examples in your browser with the
|
|
`Remix IDE <https://remix.ethereum.org>`_. Remix is a web browser based IDE
|
|
that allows you to write Solidity smart contracts, then deploy and run the
|
|
smart contracts. It can take a while to load, so please be patient.
|
|
|
|
.. warning::
|
|
As humans write software, it can have bugs. You should follow established
|
|
software development best-practices when writing your smart contracts, this
|
|
includes code review, testing, audits, and correctness proofs. Smart contract
|
|
users are sometimes more confident with code than their authors, and
|
|
blockchains and smart contracts have their own unique issues to
|
|
watch out for, so before working on production code, make sure you read the
|
|
:ref:`security_considerations` section.
|
|
|
|
If you have any questions, you can try searching for answers or asking on the
|
|
`Ethereum Stackexchange <https://ethereum.stackexchange.com/>`_, or our `gitter channel <https://gitter.im/ethereum/solidity/>`_.
