Best Solidity Courses — Quick Picks (2026)
Best overall: Ethereum and Solidity: The Complete Developer’s Guide (Udemy, Stephen Grider)
Best for hands-on dApps: Solidity Smart Contracts: Build DApps in Ethereum (Udemy)
Best academic option: Smart Contracts (Coursera, University of Maryland)
Bottom line: Solidity is the language of Ethereum smart contracts. If you know any JavaScript, Grider’s course is the fastest path from zero to deploying real contracts; pair it with a credential like the Certified Solidity Developer if you want something for your resume.
Last updated: June 2026. Written and tested by the Online Courseing team — every course below was checked live before publishing. See our review methodology.
Solidity is the dominant programming language for writing smart contracts on Ethereum and EVM-compatible chains. If you want to build decentralized apps (dApps), DeFi protocols, or NFT contracts, Solidity is the skill that gets you hired — and because its syntax borrows heavily from JavaScript, it is approachable for most web developers.
We tested the leading Solidity courses across Udemy, Coursera, and Zero To Mastery and ranked them by how well they take you from syntax to shipping a real contract. Every option below is live and enrolling as of June 2026.

How We Picked
Solidity changes fast, so we favored courses that are actively maintained and teach current tooling (recent Solidity versions, Hardhat/Foundry-era workflows) rather than abandoned 2018 material. We weighted hands-on contract deployment over passive lectures, and we checked every course is still live and enrolling. We earn a commission if you enroll through our links, at no extra cost to you — it doesn’t change our rankings.
The Best Solidity Courses, Reviewed
1. Ethereum and Solidity: The Complete Developer’s Guide (Udemy)
Stephen Grider’s course is the one most developers recommend, and for good reason. It builds your understanding from Ethereum fundamentals up to writing, testing, and deploying real smart contracts with a proper development workflow. Grider is a famously clear instructor, and the projects are substantial enough to anchor a portfolio.
Best for: developers (especially JavaScript devs) who want one comprehensive course to go from zero to deploying contracts.
2. Master Ethereum & Solidity Programming From Scratch (Udemy)
A strong alternative that leans into building real-world applications. If you learn best by shipping projects rather than working through theory, this is a great pick — it keeps the focus on practical, deployable code.
3. Solidity Smart Contracts: Build DApps In Ethereum Blockchain (Udemy)
Exactly what the title says — a project-driven course centered on building decentralized apps. It pairs well with a fundamentals course if you want extra hands-on dApp repetitions before tackling production work.
4. Ethereum Blockchain Developer Bootcamp with Solidity (Udemy)
A broader bootcamp that covers Solidity within the wider Ethereum developer skill set. Choose this if you want context around the language — how contracts fit into the full dApp stack — not just Solidity in isolation. (It’s also our top pick on our best blockchain courses guide.)
5. Smart Contracts (Coursera — University of Maryland)
The most academic option, part of Maryland’s blockchain series. It is lighter on production tooling but stronger on the why — contract design, security considerations, and the conceptual model. Audit it free or subscribe for the certificate.
6. Learn Solidity & Become a Blockchain Developer (Zero To Mastery)
ZTM’s career-focused path puts Solidity inside a structured blockchain-developer track with a supportive community. A good fit if you want a guided roadmap rather than a single standalone course.
Solidity Certifications
If you want a credential, the Blockchain Council Certified Solidity Developer and Certified Smart Contract Developer are the best-known role-based certs — we assess whether they’re worth it in our Blockchain Council review. For a fuller comparison of developer credentials, see our blockchain developer certification guide.
Is Solidity Worth Learning in 2026?
Yes — Solidity remains the primary language for Ethereum and the broader EVM ecosystem (Polygon, Arbitrum, Base, and more), which still dominates DeFi and on-chain activity. Smart-contract developers are among the best-paid in software, and demand consistently outstrips supply of genuinely skilled engineers. The bar, though, is real production skill: security and gas-efficiency matter enormously, so prioritize courses that make you build and deploy.
What You Need Before Starting
You do not need prior blockchain experience, but basic programming helps a lot — ideally JavaScript, since Solidity’s syntax is similar and most tooling (Hardhat, ethers.js) is JavaScript-based. If you’re brand new to blockchain concepts entirely, skim a fundamentals course (see our best blockchain courses) first, then dive into Solidity.
Frequently Asked Questions
How long does it take to learn Solidity?
With prior programming experience, most people can write and deploy basic smart contracts within 4–6 weeks of consistent study. Reaching production-ready proficiency (security, gas optimization, testing) takes a few months of building.
Do I need to know JavaScript before learning Solidity?
It’s not required, but it helps significantly. Solidity’s syntax resembles JavaScript, and the standard tooling (Hardhat, ethers.js, web3.js) is JavaScript-based, so JS knowledge smooths the whole workflow.
Which is the best Solidity course for beginners?
Stephen Grider’s Ethereum and Solidity: The Complete Developer’s Guide is the most-recommended starting point — clear instruction and real, deployable projects.
Are free Solidity resources good enough?
Free resources like CryptoZombies and the Coursera audit track are great for fundamentals. For a portfolio and structured depth, a paid project-based course is the better investment.
Is Solidity certification worth it?
A certification helps signal skills to non-technical recruiters, but a strong portfolio of deployed contracts matters more to engineering teams. See our Blockchain Council review for whether their Solidity cert is worth it.
