Configuring Arkhia RPC endpoints

How to configure a JSON-RPC endpoint that enables communication between EVM-compatible developer tools using Arkhia

Arkhia is a third-party organization that runs a JSON-RPC managed service. It is a "freemium" offering, meaning it has a free tier with paid components. As a managed service, it:

• Is free to use up to a point

• Does not have any sign-up requirements

• Has minimally restrictive rate limits

This combination makes it moderately straightforward to use and more reliable than the public RPC endpoint.

To connect to Hedera networks via Arkhia, simply use this URL when initializing the wallet or web3 provider instance:

Hedera Testnet

Hedera Previewnet

You will need to replace YOUR_API_KEY with an Arkhia API, and that requires the following pre-requisite steps:

Now you're ready to connect to an RPC endpoint via Arkhia!
