Solutions for a trust-free world

Parity Technologies

Parity develops open-source software for Polkadot and decentralized infrastructure.

Our GitHub repositories contain core protocol engineering, SDKs, libraries, developer tooling, and experimental infrastructure used across the Polkadot ecosystem.

Start building

If you're building on Polkadot, start with the Polkadot Developer Docs.

I want to… Start building Understand the project API / reference
Build an application with TypeScript App development docs Product SDK Product SDK API
Build a smart contract with Solidity Smart contract docs Revive Revive reference
Build a runtime or parachain Parachain development docs Polkadot SDK Polkadot SDK reference

How the documentation fits together

Start building → canonical docs

docs.polkadot.com is the starting point for tutorials, concepts, code examples, and hands-on guidance.

Understand the project → repository

Individual repositories explain what a project does, its intended audience, current status, source code, and contribution process.

Need exact technical detail → API / reference

Projects may publish generated API documentation or detailed technical reference material at paritytech.github.io.

Key repositories

The core SDK for building and maintaining Polkadot-based blockchains and runtimes.

An experimental TypeScript SDK for building applications on Polkadot.

Compiler and tooling for running Solidity smart contracts on PolkaVM.

A light client for Polkadot SDK-based chains.

Project status

Parity develops both production software and experimental open-source technology.

Check the status and maturity information in each repository before depending on a project in production.

Contributing

Parity's software is developed in the open.

Contribution instructions, development setup, issues, and project-specific guidance are maintained in the relevant repository.

For security issues, follow the security policy provided by the repository or the Parity organisation.
