Why learn the Interchain Stack?

The interchain consists of independent, interconnected, application-specific blockchains, built using developer-friendly, modular components from the Cosmos SDK, and connected with the ground-breaking Inter-Blockchain Communication Protocol (IBC).

Using the Interchain Stack, developers build entirely autonomous, sovereign decentralized apps that can also easily interconnect with both traditional software and other blockchains. Developers can rely on a well-maintained, continuously updated product stack and a large, active, and supportive community.

All this has enormous implications for blockchain technology and means the demand for developers in the interchain will continue to rise. There are currently 100+ appchains allowing for secure, trust-minimized, cross-chain interoperability, with hundreds of dApps and services built on them.

"My experience with the Academy was extremely positive. I loved the content and the instructors. This was the most useful and informative free online web3 course I've seen. I’ve learned so much about IBC and the Cosmos SDK in such a short period of time. It allowed me to branch out and explore work in other places in the ecosystem, and it led directly to a full-time job offer at the Interchain Foundation, which I was delighted to accept!"

How will you benefit?


Take the program for free

If you're accepted to the Academy, your place will be fully funded by the Interchain Foundation, so the program will be completely free of charge. All you need to do is commit the time to complete the program.


Gain the skills to start your own project

Whether you’re interested in DeFi, NFTs, gaming, DAOs, social networks, or marketplaces, you can build entirely autonomous application-specific blockchains that can easily interconnect with the Interchain Stack.

Opt out of high transaction fees and network congestion, make your own rules, and scale for mainstream adoption while becoming part of an ever-growing ecosystem.


Get certification from the Interchain Foundation 

Participants who complete the Interchain Developer Academy and pass the final exam get certified by the Interchain Foundation – the organization that stewards, maintains, funds, and advances the Interchain.


Join an industry-leading community

Developers in the Interchain are pioneers of a new era of blockchain technology. You’ll be joining a fast-growing token economy built upon a secure and stable foundation.

“Great job. It was absolutely amazing. I previously had theoretical knowledge and by far not so deep. Every time I hit a wall I was thinking that the solution must be somewhere inside the learning materials. It was a very rewarding feeling – especially because it challenged me far out of my previous comfort zone. I learned a lot and was able to apply it at my company already. I also recommended it there for my colleagues to take a look. Fantastic work. Really well organized and support was also always there!”

Martin Schäffner | Interchain Developer Academy, Cohort 4 graduate

Is the Academy right for you?

You don't need to know anything about blockchain

…but you have at least three years of professional programming experience.

You can commit to 10 hours of work per week

…to complete the seven-week program.

You’re passionate about learning about blockchain

…and pursuing a career with a blockchain company.

You’ll need to complete and pass a screening test

…to evaluate your general knowledge of software development concepts and problem-solving skills.

"I would like to congratulate the team behind this because I'm impressed with the quality of the course. It's magic, if you follow it step by step, you encounter problems, but you also have the tools to confront them, and you learn without even realizing it. I was really busy the first few weeks, but the quality of the material motivated me to finish it anyway. I hope to use this knowledge wisely and represent Interchain well. Really, really impressive work!”

Juan Carlos Frutos Hernández | Interchain Developer Academy, Cohort 4 graduate

The skills you'll gain


You’ll learn the foundational principles of blockchain technology, to clarify some concepts for developers who haven’t worked with this tech before or those who want a refresher.

We’ll cover an overview of the Interchain Stack, including a comparison to other platforms, as well as working with ATOM, wallets, and staking – for developers who have worked with other protocols and SDKs.

Main concepts

  • Gaining knowledge of blockchain technology and cryptography in general
  • Delving into the concepts of the Cosmos SDK and building an application-specific chain using the Cosmos SDK
  • Using Ignite CLI to scaffold modules for a blockchain
  • Operating nodes and validating on a Cosmos SDK blockchain
  • Making blockchains interconnected and running relaying infrastructure between IBC-connected chains
  • Building front- and backend applications using CosmJS
