Substrate tutorials

Substate tutorials is a collection of exercises that will theach you the basics of Substrate development and broaden your skillsets through real-world use cases.

Getting started

Go to the tutorial repository, fork it, clone it and start with the first exercise.
Run the crate tests, you will see they fail. Give a look to the README.md and 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. It will allow you to interact with your code through tools like polkadot.js.

Table of content

	name	objectives
0	testing	learn how to write simple tests for an existing pallet
1	pallet easy	write a really simple erc20-like pallet
2	runtime	add your pallet to a substrate runtime and launch a node
3	pallet intermediate	writing pallet is the bread and butter of substrate development, let's double down on those basics
4	coupling	pallets can interact with each other, in different complex ways
5	hooks	substrate allow you to write hooks that will multiply the possibilities of your chain
6	weights	in order to be incentive the block consensus authorities fees are collected on users transactions
7	imbalances	the supply of your chain token can vary, but there are some rules to respect when playing with it
8	genesis config	you can give your chain an initial state before launching it
9	mock	learn how to mock your runtime in order to write handy and powerfull tests
10	offchain worker	another hook that allow nodes to do complex async computation in parallel of the chain execution
