Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum.

Solidity is an object-oriented, high-level language for implementing smart contracts. Smart contracts are programs that govern the behavior of accounts within the Ethereum state.

You are reading a community translation of the Solidity documentation. The Solidity team can give no guarantees on the quality and accuracy of the translations provided.

Use npm for a convenient and portable way to install solcjs, a Solidity compiler. The solcjs program has fewer features than the ways to access the compiler described further down this page.

A contract in the sense of Solidity is a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain. The line uint storedData; declares a state variable …

Solidity is similar to Python in that it uses C3 Linearization to force a specific order in the directed acyclic graph (DAG) of base classes. This results in the desirable property of monotonicity but disallows …

Solidity provides a built-in function ecrecover that accepts a message along with the r, s and v parameters and returns the address that was used to sign the message.

With Solidity, you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets and much more! Below we list some of the most popular use cases.

Dec 18, 2025 · We are thrilled to share the Solidity Developer Survey 2024 results with you! In this blog post, we will be going over key insights and a detailed analysis of the various sections of the survey.

Solidity 是一种静态类型语言，这意味着每个变量（状态变量和局部变量）都需要被指定类型。 Solidity 提供了几种基本类型，可以用来组合出复杂类型。 除此之外，各个类型之间可以在包含运算符号的表 …
