Module guides

In-depth guides about the most common components of the Polkadot SDK. They are slightly more high level and broad than reference_docs.

Polkadot SDK Docs Guides

This crate contains a collection of guides that are foundational to the developers of Polkadot SDK. They are common user-journeys that are traversed in the Polkadot ecosystem.

The main user-journey covered by these guides is:

• your_first_pallet, where you learn what a FRAME pallet is, and write your first application logic.
• your_first_runtime, where you learn how to compile your pallets into a WASM runtime.
• your_first_node, where you learn how to run the said runtime in a node.

By this step, you have already launched a full Polkadot-SDK-based blockchain!

Once done, feel free to step up into one of our templates: crate::polkadot_sdk::templates.

Other guides are related to other miscellaneous topics and are listed as modules below.

Modules

async_backing_guide

How to enable Async Backing on parachain projects that started in 2023 or before.

enable_elastic_scaling_mvp

How to enable elastic scaling MVP on a parachain.

enable_metadata_hash
