List of RPC Providers

Below is a lists of Harmony RPC Node Providers partnered with Harmony

Before we get to the SDK and API topics, check out this list of RPC providers which you can review and setup your dedicated JSON-RPC endpoints ahead of time, to be used by your app. The endpoints are either free-to-use or have a generous allowance*, where developers can focus on developing apps, rather than setting up a blockchain infrastructure.

For example, QuickNode offers 10 million API credits for free per month.
