# Solidity Solidity is a coding language used to program "smart contracts." Smart contracts are like digital agreements that are executed and enforced automatically by code. Solidity is used on the Ethereum blockchain which is the most popular blockchain for smart contracts. Solidity is similar to other coding languages, but it is unique in its syntax and specifically designed for smart contract development. {% hint style="warning" %} It's important to use the latest released version of Solidity when deploying contracts because new features and security fixes are introduced regularly. {% endhint %} While most programming languages are "dynamically typed", Solidity is "statically typed." This means that every variable in a Solidity program must have a specific type (such as "int," "string," or "bool"), which must be declared when the variable is created. Solidity also supports inheritance (meaning that one contract can be based on another contract), libraries, and complex user-defined types. {% hint style="info" %} You can use Solidity to create contracts for a variety of purposes, such as voting, crowdfunding, and multi-signature wallets. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://dagora.gitbook.io/guides/intermediate/tutorials-and-guides/ethereum/solidity.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
