Foundations of Solidity and Smart Contract Development

Course Overview

Updated in May 2025. This course now features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. This course serves as a comprehensive introduction to Solidity and smart contract development on Ethereum. Starting with the basics, you’ll become familiar with the Remix Ethereum IDE, a critical tool for writing and testing smart contracts. Through step-by-step guidance, you’ll explore core concepts such as syntax, comments, and pragma Solidity. The course ensures you are comfortable with every aspect of the IDE, making your development journey smooth and engaging. Moving deeper into Solidity, you’ll learn how to write and deploy your first smart contract. Topics such as variables, data types, and functions are covered thoroughly, ensuring you grasp the foundational elements of smart contract coding. Exercises and solutions help reinforce your learning, making each section highly interactive. The course covers critical programming structures like if-else statements, loops, and operators, equipping you with the decision-making tools essential for smart contract logic. Finally, you will dive into more advanced topics such as scope, visibility, and memory management in Solidity. As you progress, you’ll tackle more complex coding tasks like arithmetic, logical operators, and string handling, preparing you to develop fully functional and efficient smart contracts. By the end, you’ll have not only theoretical knowledge but also practical coding skills to confidently create Ethereum-based applications. This course is ideal for beginners in blockchain development, software engineers interested in decentralized applications, or anyone with basic programming knowledge. No prior experience with Solidity is necessary, but familiarity with basic programming concepts is recommended.
