Traditional learning models are all about getting a degree - but we’re about getting that dream job. Find out about the industry partnerships we’re growing every day to help our graduates fast forward their careers.


In our course, you’ll learn blockchain, smart contracts, NFTs, and more so you finish with the qualifications to land a Web3 job—and the portfolio to prove it. 

We worked with industry experts to build our new Web3 Development course, based on the skills and tech stack most commonly needed for Web3 developers and related positions. With our course, you’ll learn Web3 through on-demand instruction, live events with experts, and hands-on projects on your schedule. You will have access to this flexible course for one year, and it is designed so you can upskill while working full-time, in as few as 10 weeks.

“This course was developed by people from a wide range of professional experience and, as a result, has everything for people who are just starting with Web3 and those who know a little bit but want to learn more.”

Manraj Jawanda
Web3 expert and Web3 Development sprint developer

Graduates of the new BloomTech Web3 Development course will gain the skills and tooling experience necessary to build production decentralized apps (dapps). The program explores current trends in Web3 development including NFTs, DeFi, and cryptography.

In the course, you will learn Web3 best practices for writing and testing smart contracts in Solidity, an extremely popular contract programming language. You will learn how to test and protect your smart contracts. This is an exceptionally in-demand skill, considering vulnerabilities have caused companies to lose millions of dollars in attacks.

The Web3 course will cover deployment to both Polygon and Ethereum mainnet. Please note: Several coding practice exercises and projects require using test coins to complete transactions. We will never ask you to use real coins in this course.

Flexible Schedule

The BloomTech Web3 course is designed to be flexible so you can learn Web3 Development on your own schedule, while you work. Our Web3 Development course is broken into 10 sprints, each of which includes on-demand recorded instruction and a hands-on project. Completing a sprint "unlocks" the next sprint.

Each sprint requires approximately 15 hours of work. This time commitment includes:

  • 2 hours of learning via recorded, expert-led videos and tutorials
  • 2 hours reviewing study materials and completing quizzes
  • 11 hours completing the sprint project
  • Optional: Live office hours, Q&As, and industry expert events

If you dedicate approximately 15 hours of work per week, you can complete the course in as few as 10 weeks. The course adapts to you and your schedule, so you can accelerate or slow down your pace.

The course is open to International learners. Please be aware that most live sessions, which are optional, take place weekdays between 1-9pm PT, with office hours on weekends, too.

“I work a full-time job and being able to go through the course at my own pace has [...] allowed me to work on it in a way that best fits into my schedule.”

Frequently asked questions

What is Web3?
Down arrow
Web3, often referred to as the next phase of the internet, is based on the concept of decentralized peer-to-peer networks. Applications and code are encrypted and distributed across all the computers participating in the network. As a result, there is no single point of failure or central authority, making it private, tamper-resistant, and easily verifiable. For more information, read our intro to Web3 here.
What is the format for your Web3 Development course?
Down arrow
Our Web3 Development course is an online, on-demand program you can work through at your own pace. You’ll learn Web3 skills through recorded lessons taught by industry experts, study materials and resources, and independent projects that apply the skills you learn. You can also attend optional live events, get support during office hours, and connect with other professionals in our BloomTech online community. 
Who is the Web3 Development course for?
Down arrow
This program is designed for software engineers or developers who want to specialize or keep their skills up-to-date. The course is not for beginners or those looking for their first job in tech.
