Excellent Free Tutorials to Learn Solidity

Solidity is an object-oriented, high-level language for implementing smart contracts. Solidity lets you program on Ethereum, a blockchain-based virtual machine that allows the creation and execution of smart contracts, without requiring centralized or trusted parties.

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.

Solidity was influenced by C++, Python and JavaScript. Like objects in OOP, each contract contains state variables, functions, and common data types. Contract-specific features include modifier (guard) clauses, event notifiers for listeners, and custom global variables.

Here’s our recommended free tutorials to learn Solidity.


1. Learn Solidity in Y minutes by Nemil Dalal and contributors

This document primarily discusses syntax, and so excludes many popular design patterns.

3. Solidity tutorials

This tutorial is part of a Solidity tutorial series:

Part 1: The Five Types Model
Part 2: Action-Driven Architecture
Part 3: Solidity Language Features

4. Style Guide by Solidity

This guide is intended to provide coding conventions for writing solidity code. This guide should be thought of as an evolving document that will change over time as useful conventions are found and old conventions are rendered obsolete.
