The Polkadot SDK repository provides all the components needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way.

Note
Our release process is still Work-In-Progress and may not yet reflect the aspired outline here.
The Polkadot-SDK has two release channels: stable and nightly. Production software is advised to
only use stable. nightly is meant for tinkerers to try out the latest features. The detailed
release process is described in RELEASE.md.
stable releases have a support duration of three months. In this period, the release will not
have any breaking changes. It will receive bug fixes, security fixes, performance fixes and new
non-breaking features on a two week cadence.
nightly releases are released every night from the master branch, potentially with breaking
changes. They have pre-release version numbers in the format major.0.0-nightlyYYMMDD.
Polkadot SDK Version Manager: A simple tool to manage and update the Polkadot SDK dependencies in any Cargo.toml file. It will automatically update the Polkadot SDK dependencies to their correct crates.io version.
The security policy and procedures can be found in docs/contributor/SECURITY.md.

We always recognize valuable contributions by proposing an on-chain tip to the Polkadot network as a token of our
appreciation.
Development in this repo usually goes hand in hand with the fellowship organization. In short,
this repository provides all the SDK pieces needed to build both Polkadot and its parachains. But,
the actual Polkadot runtime lives in the fellowship/runtimes repository. Read more about the
fellowship, this separation, the RFC process
here.
This repository is the amalgamation of 3 separate repositories that used to make up Polkadot SDK, namely Substrate, Polkadot and Cumulus. Read more about the merge and its history here.
