A complete Solidity course: free, structured and job-focused
Decentralized applications run on smart contracts, which require precise, secure programming to prevent costly errors. This free Solidity course teaches you how to write that code from scratch. Across 6 modules and 24 video lessons, you'll start with Introduction to Solidity before moving into writing actual Smart Contracts. From there, the curriculum covers Functions in Solidity, Control Structures in Solidity, and Solidity Events and Modifiers. You'll finish by mastering Solidity Inheritance and Libraries. The entire program takes about 1 hours, giving you a fast but thorough foundation in blockchain development.
Theory alone won't make you a blockchain developer, so you will apply your skills through four hands-on projects. You'll practice Implementing a Decentralized Voting System for a Global Tech Giant and Developing a Supply Chain Management Smart Contract for a Leading E-commerce Startup. You will also get experience Creating a Tokenized Rewards Program for a Top Financial Services Company and Building a Decentralized Marketplace for a Revolutionary Blockchain Startup.
LearnTube makes mastering these skills highly effective. We take the best YouTube video lessons, starting with your first lesson on Solidity Basics, and organize them into a structured path. An AI tutor gives you a quick quiz after every single video to make sure you actually understand the concepts. Learning is completely free, and you can add a paid certificate at the end to show employers what you know. You'll join over 60,000 learners building their tech careers with us.

Why learners choose LearnTube
Real reviews from Google. You learn free, you get assessed free, and you pay only if you want the certificate.
Though I have 11 years of experience as an HRBP, the course helped me refresh my knowledge and gave me insights into new trends in the market. The modules were clear and easy to understand, and the quizzes were well designed. I have added the certificate to my LinkedIn profile.
I had a lot of doubts while learning, but the AI chatbot answered them in detail with simple summaries. The videos on the platform saved me a lot of time as I didn't have to search YouTube and watch random content.
Just earned my certificate in HR Management from LearnTube.ai! The platform is user-friendly and the assessment was a great way to validate my knowledge. Feeling proud of this accomplishment!
I enrolled in a LearnTube personalized course to get into a Data Analytics role. It helped me learn SQL in depth and gave me hands-on experience with Power BI. I attached the LearnTube certificate to my CV, it added credibility to my profile, and I'm currently in the interview process.
The interface is user-friendly and intuitive, making it easy to navigate the course. I encountered no errors during my time using the platform, which was a refreshing change from other online learning platforms.
Just cleared the Business Analyst assessment and got certified! Loved how the course simplifies big concepts like data-driven decision making into short, practical lessons. The automated quizzes kept me on track the whole time. Perfect boost for my resume!
The certificate gave me a real edge during my B.Tech. By the time I graduated, I had skills that set me apart from my peers, and the certification opened up more job opportunities. It gave me the confidence to stand out during interviews.
I manage many software projects as a General Manager and was looking for a good certification program to stay competitive. After researching many programs, I chose LearnTube and it was much better than I expected. The material is well-organized and practical, and what I liked most is the lifetime access.
Frequently asked questions
Everything learners ask before starting this Solidity course.
Is this Solidity course really free?
Yes, all 24 video lessons and the AI-driven quizzes are completely free to access. You can learn everything from basic syntax to advanced inheritance without paying anything. The only optional cost is if you want the verified certificate.
Do I get a certificate after completing the smart contract modules?
You can opt for a paid certificate once you finish all 6 modules and pass the AI quizzes. This certificate proves your new blockchain skills to our 900+ hiring partners and looks great on your resume.
How is this different from watching random YouTube tutorials?
We organize the best YouTube content into a logical path so you don't get lost. Our AI tutor also tests your knowledge after every video, ensuring you actually understand concepts like modifiers rather than just watching passively.
What software do I need installed to learn Solidity?
You do not need to install any heavy software to start learning. Most beginners use Remix, a free browser-based IDE, to write, compile, and deploy smart contracts directly from their web browser.
Will I build real projects during this program?
Yes, the curriculum includes four practical projects. You will build a decentralized voting system, a supply chain management contract, a tokenized rewards program, and a decentralized marketplace to build a strong portfolio.
Can a beginner learn smart contract programming?
Basic programming knowledge helps, but the course starts from the ground up with Solidity Basics. If you understand basic logic like loops and conditional statements, you will be able to follow the lessons and build functional contracts.
