How to Start Your Ethereum Development Career

If you want to be an Ethereum developer, but you don’t know where to start, what tutorials to follow or what courses to take, you will find in this article all the information and resources you need right now. From basic directions and useful links to paid courses with the best investment return and certifications available to you anywhere in the world!

What is an Ethereum Developer?

An Ethereum developer is a person who writes code in order to create decentralized applications (dApps) and smart contracts which run on the Ethereum blockchain.

Ethereum development is a hot market right now, and it’s common for Ethereum development jobs to pay anywhere from $50,000 to $100,000+ a year.

Many people become interested in being an Ethereum or other cryptocurrency developer in different ways. Some people start out as investors who then want to learn more about cryptocurrency. Some start out as IT professionals who are looking for something different. Whatever your background may be, there are development opportunities for you.

If you’re looking for an opinion from the perspective of a professional, here is an interview with advice on building a successful blockchain development career.

Understanding dApp development

DApps are decentralized applications that exist on the Ethereum network. The only difference between a dApp and a standard application is the Ethereum framework. With a dApp, the backend code is run on decentralized peer-to-peer networks as opposed to centralized servers. dApps can have user interfaces and front ends written in any computer language. However, to connect the dApp to the Ethereum blockchain, developers utilize smart contracts.

dApps = front end + smart contracts

All data is stored cryptographically on the blockchain. The decentralized nature of the blockchain prevents hackers from getting user information. The programming language that is used to create smart contracts is called Solidity. Solidity is strongly influenced by both Javascript and Python.

Core EVM Development

Writing programs in Solidity makes them compatible with the Ethereum virtual machine (EVM). The EVM is a runtime environment for Ethereum smart contracts. It is powered by every participant in the peer-to-peer network. The EVM organizes, handles, and processes smart contracts based on how they were programmed. Whether a dApp is written in Javascript, C, Go, or any other programming language, it can be connected to the Ethereum virtual machine, and thus the Ethereum blockchain through Solidity-based smart contracts.

Free Ways To Start Learning

Getting into Ethereum application development is difficult but highly rewarding. Unless you are already an expert full stack developer, learning the different development paths may even overwhelm you, but we’ve created a guide to help you get into learning dApp development for free.

Learning the basics

As mentioned, starting out in Ethereum development isn’t easy. Of course, to get into the field you’ll need to learn the basics. Here are some steps on how to get into Ethereum development for free:

A great starting reference to the following steps, including example code to test with is A Programmer’s Guide to Ethereum and Serpent.

Learn Solidity

Solidity is a higher-level coding language used for implementing smart contracts. It is the only officially supported language, and it is most similar to JavaScript. You would use Solidity to write applications that simulate financial situations such as a lottery or a loan, which are then used to test out the smart contracts you’ve programmed.

Solidity is an alternative to Serpent, which is better for Python users. Coders who are more familiar with C or Java would most likely prefer Solidity. This link provides a detailed breakdown on Solidity:

Understand the Concept of Ethereum

Ethereum was formed as an alternative to Bitcoin. Both are based on the same blockchain technology, though Bitcoin’s is more outdated compared to Ethereum. While Bitcoin focused purely on digital transactions, Ethereum wants to be a platform for which developers can create decentralized apps. A decentralized app exists on multiple nodes throughout the blockchain, rather than a physical server. These nodes ensure that the network can never go down, nor can it be interfered with by hackers. Any information shared with the dApp is entirely secure.

dApps are run by smart contracts which are programmable sections of the Ethereum network that you can assign a value. If a specified set of conditions are met, these sections unlock and provide value to the user.

Learn The Truffle Framework

Truffle is the most popular framework for developing on Ethereum. It provides Ethereum developers with a ton of quality-of-life enhancements, sort of like how WordPress makes life easier for web developers.

Here is a tutorial index that provides all of the different aspects of Truffle.

The official Truffle documentation can be found here.

Build a dApp

Knowing how to build an app is standard fare for Ethereum developers. If you’re looking to build a dApp, there are multiple resources available to you:

  • is a free way to learn about Solidity and the basics of writing your own smart contracts.
  • dApps for Beginners offers a very detailed breakdown on how to build your first contract for your dApp.
  • Here is a blog post teaching you to write an adoption tracking system with Truffle.
  • And finally, this blog post is a fantastic place to learn as well.

Free Courses

Princeton offers a free blockchain course here. This Medium blog also has a list of free courses to take.

When you feel ready to take the next step up from free learning tools, paid courses are the way to go. Of course, with paid courses the goal is to get a good return on investment.

Paid courses have some distinct advantages over free courses. They often go more in-depth and are presented more professionally. With paid courses, a curator can help answer any of your questions. Also, there are often opportunities to make connections and find job opportunities from within the course. Here are some great paid courses to choose from: offers three courses: Ethereum 101, Ethereum Developer Course, and Blockchain for Technical Executives and Analysts. Both the Ethereum Developer Course and the Blockchain for Technical Executives courses run for about three months and have about a 40-hour workload. If you score an 80% or higher at the final exam for the course, you will receive an Ethereum blockchain certificate. These certificates are verified through the Ethereum blockchain and can be displayed on places like LinkedIn.

Prices: The Ethereum 101 course is free, the Ethereum Developer Course costs €1,450, and the Blockchain for Technical Executives and Analysts course costs €2,350.

There is no credited author for the B9lab courses, rather they are a culmination of multiple experts’ knowledge and experiences.

Having a certification that proves that you have mastered blockchain coding and other blockchain concepts can be extremely helpful for landing an Ethereum developer job. It demonstrates the fact that you have taken the time to build the development skills necessary, and that an authority has validated your knowledge in this field.

In addition to the certificates from the courses listed above, offers certifications for Bitcoin development. However, it will soon offer a certification for Ethereum developers called “Certified Ethereum Developer (CED.)” According to Cryptoconsortium, “A Certified Ethereum Developer is knowledgeable about the Ethereum blockchain, Ethereum transactions, the Solidity programming language and how to use it to write smart contracts on the Ethereum network.” To earn this certificate, students have to pass an exam that covers various aspects of Ethereum development.

Ethereum is still extremely new and so is blockchain in general. So, companies who are getting into dApp and smart contract development for the Ethereum blockchain would want to see that job candidates have some sort of credentials to prove their knowledge. Having a B9labs certificate is an excellent way to demonstrate that. provides a blockchain training course. If you complete it, you will receive the certification of “Blockchain Expert” from Edureka. This certification is proof that you have mastered the essential concepts involved in blockchain development. It is very similar to the other certificates on this list. However, to receive this certification, you will need to complete multiple classes, each requiring about 20 hours worth of work. After the classes, you should know how to set up your own blockchain, deploy smart contracts on the Ethereum blockchain, and much more. offers the “Certified Blockchain Professional” certification. This certificate proves that you have not only completed the course offered by the Blockchain Institute of Technology, but that you are also capable of providing blockchain development for companies on a professional level. This is a good certification to have if you are trying to land a blockchain development job. offers a “DCC Certification.” This certification is given to people who take the DCC course, and successfully pass the DCC exam. The Digital Currency Council claims that their certification proves that you are a “leader and respected authority in the Bitcoin ecosystem.” So, this certificate is better for people who would like to go into Bitcoin development as opposed to Ethereum development. If this is for you, or if you would like to prove your expertise in both Bitcoin and Ethereum, a DCC certificate would be a nice supplement to any Ethereum certificates that you earn.

Ethereum and blockchain certificates are especially beneficial right now considering the fact that most colleges and universities do not offer traditional a bachelor’s or master’s degree in things like Ethereum development. In the near future, however, there is a good chance that they will. But for the time being, most do not, even if they do offer a course or two here and there about blockchain technology. Having an official certification from Cryptoconsortium, B9labs, or the other places listed in this article can really help you stand out against other developers for Ethereum development positions.


Becoming an Ethereum developer could be an excellent career choice for you. Ethereum is one of the blockchains that has the most potential to grow rapidly in the near future. Unlike many other blockchains, Ethereum is designed to be a platform for helping dApps to run. This makes it function as a sort of hub of computing activity. There are potentially vast opportunities in this field.
