Description

Solidity is a powerful and popular programming language that forms the backbone of the decentralised revolution. As the primary language for writing smart contracts on blockchain platforms like Ethereum, Solidity empowers developers to create secure, transparent, and self-executing contracts.

With Solidity, developers can build a wide range of decentralised applications (dApps) that are reshaping industries and disrupting traditional systems. Whether it's decentralised finance (DeFi) protocols, non-fungible tokens (NFTs), decentralised exchanges (DEXs), or decentralised autonomous organisations (DAOs), Solidity provides the foundation for trustless and tamper-proof interactions.

In this lab, you will learn how variables are declared in the Solidity programming language and how to use them.

Learning objectives

Upon completion of this beginner-level lab, you will be able to:

  • Declare a storage variable. 
  • Change access modified of the variable. 
  • Declare a local variable. 

Intended audience

  • Individuals studying software engineering.
  • Individuals who have an interest in crypto technologies.
