Polkadot Hacker House



The Polkadot Hackathon Global Series North America Edition is the second in a series of hackathons that brings the cutting edge of blockchain to a global community. This event may be focused on North America, but is open to all. Whether you’re an experienced blockchain dev, want to learn more about building on Polkadot, or are new to the ecosystem, a range of activities and a more than US$270,000 prize pool are on offer for you.

Focusing on Substrate, Polkadot, and Kusama, this hackathon is open to both individuals and teams anywhere in the world. As well as blockchain building, participants can take advantage of mentoring hours and networking opportunities that can be invaluable for starting new projects or building teams.

What is Polkadot?

Polkadot is a layer-0 protocol and multichain network founded by Dr. Gavin Wood, co-founder and former CTO of Ethereum. Polkadot provides security, scalability, and interoperability to a diverse network of layer-1 blockchains called parachains. Polkadot offers several advancements over legacy blockchain networks, from governance to customization, upgradeability, energy efficiency, and more.

What is Kusama?

Built on nearly the same codebase as Polkadot, Kusama is a layer-0 protocol and multichain network. Kusama provides security, scalability, and interoperability to a diverse network of layer-1 blockchains called parachains, and serves as Polkadot’s ‘canary net’. Designed for radical innovation and experimentation, Kusama is used both as a live, value-bearing proving ground for Polkadot technology and as a deployment environment for early-stage startups and experimental blockchain use cases.

What is Substrate?

Substrate is a blockchain development framework for building and customizing parachains in the Polkadot ecosystem, as well as standalone or ‘solo’ chains. It features a completely generic state transition function and modular building blocks for common blockchain components like consensus, networking, and asset creation. By building with Substrate, development teams can significantly speed up production, reduce the cost of building a blockchain, and get much more power and flexibility than building on a smart contract platform.



Interfaces & Experiences

This track is dedicated to building your understanding of UI and UX fundamentals, including best practices specifically for blockchain development. Gain experience in building a wide variety of interfaces and user experiences that chains can adopt.

DAO & Governance

Discover the breadth of DAO functionality and governance mechanisms in this track. Get the opportunity to explore ideas, including the creation of new DAOs and the necessary tooling involved in this development process, as well as new governance mechanisms and pallets.

Web3 & Tooling

A diverse track focused on all kinds of tooling and applications that can be used to expand Web3. Those interested in building a better web can explore the use cases for open-source technologies for a society run on peer-to-peer networks.


Builders can make use of this track for the multitude of DeFi-related solutions, including DEXs, AMMs, and stablecoins. Learn how to not only develop new financial primitives, but also work towards the integration of existing ones, such as breaking the barriers of assets between blockchains. This all contributes to helping build wider adoption of DeFi.


This track for developers interested in the use cases for NFTs will explore the scope for their creation across multiple industries, including gaming, art, real estate, logistics, and general collectibles. The scope includes exploring the importance of optimizing for complex NFT use cases, and blockchain-agnostic NFT platforms that enable cross-chain functionality.

Participants' Guide

We have compiled a complete guide for you, where you can find a lot of information about our hackathon. The guide also details what ecosystem challenges we have for you, and you can find all the relevants resources as well.

Important! General Submission Requirements & Rules

If you are submitting a Substrate chain, the submission must be one of the following formats:

  • a live running site or running chain and provide an endpoint, if you are running a substrate chain (highly recommended)
  • a Docker image (highly recommended)
  • a Linux executable (discouraged)
  • code with detailed build instructions (strongly discouraged)

If you are using Substrate, use the latest version.

If you are submitting for an ecosystem team (hackathon sponsor) challenge, clearly state which challenge you are building for.

Include in your submission’s readme file:

  • Project title
  • Project description (minimum 150 words)

Provide a way to access the project for judging and testing by including a link to a repo hosting the application’s code and any other deployment files and testing instructions.

Must have an open source licence (GPL, MIT, Apache, and Unlicense are accepted, others may be considered on a case by case basis).

Must use or be made for the Polkadot/Kusama/Substrate ecosystem.

Ecosystem challenge requirements

Some of the ecosystem challenges have specific requirements for submission and consideration. Please consult our Participants Guide's relevant pages for each team's requirements.
