Introduction to Polkadot SDK - Substrate & FRAME

Developed by the Technical Education team at the Web3 Foundation, this course provides a comprehensive overview of the Substrate blockchain framework and building blockchains.


Before starting, it would be wise to either have experience with Rust, or have taken our Intro to Rust course. Substrate depends heavily on Rust, and it will be elaborated on extensively in this course.

This course will provide a solid foundation in navigating the creation and modification of custom blockchain modules, called pallets. This course will serve as an introduction into becoming a Substrate developer, the factors involved, as well as a guided, hands on portion to building a custom FRAME pallet.

In this course, you will:

  • Learn about FRAME, the primary mode of implementation for Substrate
  • Learn at high-level how storage, the runtime, and pallets work in FRAME
  • Learn how to build a basic pallet and run a custom blockchain via a template
  • Learn basic testing of a FRAME pallet
  • Learn best practices and important considerations when building a FRAME pallet
  • Build and deploy a basic, social-network like blockchain pallet called connect
