Frequently asked questions
- Udemy and Eduonix are best for practical, low cost and high quality Solidity courses.
- Coursera, Udacity and EdX are the best providers for a Solidity certificate, as many come from top Ivy League Universities.
- YouTube is best for free Solidity crash courses.
- PluralSight, SkillShare and LinkedIn are the best monthly subscription platforms if you want to take multiple Solidity courses.
- Independent Providers for Solidity courses & certificates are generally hit or miss.
Functional: Solidity language is used for smart contracts. This mostly takes care of money-related needs (such as auctions, crowdfunding, or wallets with a multi-signature feature). However, you can create other decentralized applications too (say, for voting).

Yes and No. Certified Solidity developers on average make more money. Having a Solidity certificate greatly increases the chance of landing an interview and can open otherwise closed doors. Coursera, Udacity and EdX offer excellent certificate options for impressing your future employers. Eduonix, Udemy and several other providers offer certificates, but they aren't as reputable. If you have a Computer Science Degree, certificates are not as important. Still, many employers won't care about certificates, but rather your interview skills, experience and/or skills assessment.

Ethereum and Solidity: Build Dapp with VueJS (2018)
4.1
Build Decentralized Application using VueJS and Smart Contracts written in Solidity
What You'll Learn
- Learn how to create simple smart contracts
- Learn how to develop Decentralized Applications
2
Learn Solidity: Programming Language for Smart Contracts (2017)
3.8
Have you heard of Ethereum & Smart Contracts?
Have you ever thought of writing smart contracts or your own cryptocurrencies?
Do you know smart contracts are written in Solidity Programming Language?
Solidity is a programming language for writing smart contracts which run on Ethereum Virtual Machine on Blockchain.
It is a contract-oriented, high-level language whose syntax is similar to that of JavaScript and it is designed to target the Ethereum Virtual Machine.
In this course I will teach you everything related to Solidity to build Smart Contracts based Blockchain application on Ethereum. We will learn what:
What is Ethereum, Smart Contracts & Blockchain?
What is Solidity & Ethereum Virtual Machine?
How to install & Setup Solidity Development Environment?
How to write first basic smart contracts?
Data types, control structure, functions, inheritance, mathematical operations, etc.
How to deploy & test smart contracts in Solidity?
Building 2 ApplicationsVoting Ballot on BlockchainFundRaiser Application
This course will enable you to build any kind of Blockchain application on Ethereum using Solidity which is most common language for writing Ethereum Blockchain.
Who this course is for:
Anyone interested in being Ethereum DeveloperAnyone interested in building decentralized application (DApps)Anyone interested in Learning Solidity Language for Smart ContractsAnyone interested in learning how to build their own cryptocurrency

Ethereum and Solidity: The Complete Developer's Guide (2025)
4.3
Solidity taught through a Kickstarter-style crowdfunding app and a long React front-end, with concepts reviewers still praise but tooling they say has aged.
Best for: JavaScript developers who want to understand how Ethereum contracts work and are fine fixing outdated package versions themselves.
Pros
Cons
-
- Reviewers call Grider's teaching clear and thorough, especially on problems before solutions
- Builds from simple contracts up to a Kickstarter-style app with a front-end
- Covers contract and front-end integration through several full projects
- Concepts hold up, and one reviewer updated the old libraries on their own
-
- Reviewers report version errors, so code often fails with current packages
- Last updated April 2025, and reviewers call the NextJS material outdated
- No quizzes or coding exercises, and one 2018 review found Q&A answers thin
