Exercises to learn substrate

Who is this tutorial for?

This tutorial is for developers willing to learn the basics of Substrate development and broaden their skillsets through real-world use cases.

You will need a solid grasp of the Rust programming language before you start to learn Substrate.

Some good entry points to learning Rust 📚

As officially referred to here, the best paths to get started with Rust are:

And of course, you should always challenge yourself with a side project or two.

What is Substrate?

Substrate can be described as a blockchain framework — specifically, a framework for building customized blockchains. It is built on the Rust programming language, which makes use of novel design patterns to enable the development of code that is safe and fast.

To give some context, Polkadot is a layer-0 protocol and multichain network laying the foundation for the future of Web3. Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network.

How to train?

  • fork this repository
  • clone it on your machine
  • code until all tests pass

If you want to run your pallet in a real runtime, you can easily edit the substrate-node-template and add your pallet to its runtime.

What's in those exercises?

We designed the exercises to teach you:

  • how to use the numerous features of Substrate
  • some good Substrate practices
  • some blockchain core principles

If you are stuck, you can always check the solution branch. It's not cheating, just learning 🧑‍🎓

Thanks to our sponsors

This tutorial is made possible thanks to a grant from the Web3 Foundation. Thanks a lot to them!
