Polkadot SDK

Substrate to Polkadot SDK

In May 2023, Parity Technologies started moving the three repositories that contained substrate, polkadot, and cumulus, formerly independent in development and branding, under one new mono-repo called polkadot-sdk. Consequently, the runtimes of the Polkadot and Kusama relay chains, and their system chains were moved to be maintained by the Polkadot fellowship.

This transition gave birth to a new vision in which these tools are seen from the lens of being part of polkadot-sdk while still being independently useful.

Most impacted in this transition is Substrate, and part of this impact is the gradual deprecation of this website. The content on this website is no longer maintained and will be gradually moved to a new home. Consider the resources below as primary sources of information.

You may still access the old content of this website in the navbar, but be aware of the fact that some content might not be up to date.

Note that this does not impact the development of Substrate as a framework. Substrate, as a framework, is still being maintained with full steam as a part of polkadot-sdk, and retains its full ability to be used to build both standalone blockchains, or Polkadot powered parachains.
