Proposal overview

Chainstack would like to propose a partnership with Harmony to help the ecosystem grow by making highly accessible nodes available to as many builders as possible. Our mission is to power a Web3 for All. The collaboration will entail a engineering effort to onboard Harmony on the Chainstack platform, and in return making nodes available free of charge to the Harmony community to support the growth of the ecosystem.

We will also work alongside you to educate the developer community about Harmony and prompt experimentation/building on the protocol with targeted marketing and events. Full support of Harmony on Chainstack will include enterprise-grade documentation with tutorial and quick guides. We see ourselves not just as an infrastructure provider, but as a developer community catalyst. We have excellent user support and able to troubleshoot very quickly with our customers whenever needed.

Chainstack is known for our best-in-class engineering, running nodes-as-a-service and public RPC endpoints that are preferred by the respective communities due to our reliability. We handle very complex and customised set ups behind the scenes, combining an intuitive turnkey platform and public RPC endpoints, to very sophisticated DevOps as needed. We love being at the cutting edge and have a commitment to R&D, including several patents already in use on the platform. When it comes to pricing, in line with our mission, we want to make node infrastructure accessible and cost-effective for all. Adding on, Chainstack also provides flexible hosting options to developers and builders, with nodes available on all the major public clouds and geographies, catering to a diverse set of needs of each protocol’s community, including co-location. We give options and help with reducing the risk of having the entire infra on one provider and/or with limited geographical spread.

With this partnership, Chainstack will bring greater flexibility and options to Harmony’s community with availability of completely public API for developers, including free private node endpoints. In addition to our full managed node service, Chainstack is looking to publish application development tutorials and documentation for Harmony’s community use, incentivise and work with a developer community of over 25K+ to build on Harmony.

Happy to announce that our public Harmony API is live :tada:

How did we build it to be the most reliable and fast public API for Harmony? Here’s a little diagram :point_down:

Anyone can access our public API for Harmony mainnet shard 0 using the following endpoints:

  • HTTP
  • WebSocket wss://

How to use them with your MetaMask wallet? Short instructions for custom RPC configuration on Desktop and Mobile.

Feel free to provide feedback in the :ice_cube: harmony channel in Chainstack Discord :raised_hands:
