Quick answers

What is polkadot-sdk?
The core software development kit for building blockchains on the Polkadot network.
What does polkadot-sdk do?
The Polkadot SDK is a highly modular toolkit utilized by engineers to build customized, interoperable blockchains (parachains) that connect to the Polkadot ecosystem. It encompasses the Substrate framework, providing all necessary cryptographic, networking, and consensus primitives required to launch a secure network from scratch. Developers use its highly adaptable 'FRAME' architecture to rapidly construct domain-specific runtime logic by composing pre-built modules. It serves as the foundational infrastructure layer, ensuring that entirely custom blockchains can seamlessly communicate and share security within the broader Polkadot relay chain architecture.
Who is polkadot-sdk for?
Blockchain engineers, protocol designers, and infrastructure developers building highly customized decentralized networks. It demands a very strong understanding of Rust and complex distributed systems consensus.
How do I get started with polkadot-sdk?
git clone https://github.com/paritytech/polkadot-sdk.git
How popular is polkadot-sdk on GitHub?
QuipNetwork/polkadot-sdk has 5,459 stars and 14 forks on GitHub, and gained -1 stars in the last 7 days.

What polkadot-sdk does

The Polkadot SDK is a highly modular toolkit utilized by engineers to build customized, interoperable blockchains (parachains) that connect to the Polkadot ecosystem. It encompasses the Substrate framework, providing all necessary cryptographic, networking, and consensus primitives required to launch a secure network from scratch. Developers use its highly adaptable 'FRAME' architecture to rapidly construct domain-specific runtime logic by composing pre-built modules. It serves as the foundational infrastructure layer, ensuring that entirely custom blockchains can seamlessly communicate and share security within the broader Polkadot relay chain architecture.

Blockchain engineers, protocol designers, and infrastructure developers building highly customized decentralized networks. It demands a very strong understanding of Rust and complex distributed systems consensus.

  • Substrate framework: Provides the core, heavily audited networking, consensus, and cryptographic primitives needed to run a blockchain.
  • FRAME architecture: Allows developers to rapidly compose entirely custom runtime logic using a library of highly modular, pre-built pallets.
  • Interoperability protocols: Includes native support for cross-consensus messaging (XCM), allowing secure communication between disparate parachains.
  • Shared security: Enables custom chains to easily connect to the main Polkadot Relay Chain to inherit its massive economic security.
  • Forkless upgrades: Integrates WebAssembly (Wasm) runtimes that allow the network to seamlessly upgrade its core logic without hard forks.

Where teams use it

Parachain development

Blockchain engineers utilizing the FRAME pallets to build a highly specialized decentralized finance network connected to Polkadot.

Enterprise consortiums

Corporations leveraging the SDK's modularity to build entirely private, permissioned blockchains with custom consensus rules.

Smart contract platforms

Developers building a specialized chain optimized exclusively for extremely high-throughput WebAssembly smart contract execution.

Cross-chain messaging

Protocol designers using the embedded XCM libraries to securely transfer complex assets between entirely different blockchain architectures.

Polkadot SDK

GitHub stars  GitHub forks

StackExchange  GitHub contributors  GitHub commit activity  GitHub last commit

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.

⚡ Quickstart

If you want to get an example node running quickly you can execute the following getting started script:

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/paritytech/polkadot-sdk/master/scripts/getting-started.sh | bash

👩🏽‍💻 Building

In order to build this project you need to install some dependencies, follow the instructions in this guide.

🎯 Build targets

When building full runtimes, the WASM builder takes care of all required configuration.
For individual crates, however, there are a few caveats when targeting no_std.

WASM

Set RUSTFLAGS="--cfg substrate_runtime" when building for WASM. See the WASM build in the Polkadot SDK Documentation.

PolkaVM

PolkaVM builds require some riscv32 or riscv64 target architecture.
See the CI example: RiscV-build.

📚 Documentation

🚀 Releases

Current Stable Release  Next Stable Release

The Polkadot SDK is released every three months as a Polkadot stableYYMM release. Each stable release is supported for one year with patches. See the next upcoming versions in the Release Registry and more docs in RELEASE.md.

You can use psvm to update all dependencies to a specific version without needing to manually select the correct version for each crate.

🛠️ Tooling

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.

🔐 Security

The security policy and procedures can be found in docs/contributor/SECURITY.md.

Polkadot Fellowship

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.

History

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.
