The goal of this page is to provide an overview of the open-source Harmony Tech Stack.
This is a living document and we are relying on our community to contribute to it and help maintain it. Please feel free to make edits and additions via pull requests. We apologize if we missed your project!
The Harmony Tech Stack consists of the open-source technologies contributing to and relying on Harmony. It is meant to be used for decentralized application (Dapp) development within numerous verticals including DeFi, Gaming, Provenance and many others not pictured below.
