How to configure a JSON-RPC endpoint that enables communication between EVM-compatible developer tools using Hashio. Hashio is a public RPC endpoint hosted by Hashgraph that runs an instance of the Hiero JSON-RPC Relay. As a public endpoint, it:
  • Is free to use
  • Does not have any sign-up requirements
  • Has significantly restrictive rate limits
While this combination may be considered less reliable, it offers the highest levels of ease of use among RPC endpoints. To connect to the Hedera networks via Hashio, simply use one of these URLs when initializing the wallet or web3 provider instance:
The corresponding chain IDs are: No further settings or configurations are needed!
Please note: Hashio is for development and testing purposes only. Production use cases are strongly encouraged to use commercial-grade JSON-RPC relays or host their own instance of the Hiero JSON-RPC Relay.
