JSON-RPC Relay

The Hedera JSON-RPC Relay is an open source project that implements the Ethereum JSON-RPC standard. The JSON-RPC relay allows developers to interact with Hedera nodes using familiar Ethereum tools. This allows Ethereum developers and users to deploy, query and execute contracts as they normally would.

Available versions below.

JSON-RPC Testnet (Free & Paid tiers)

For this version all free queries will be redirected to Arkhia's Mirror node, while a wallet attached to the relay that tops up automatically is set for paid queries to Hedera's Consensus Nodes. With the testnet version you will be able to try out the sanity of our services including Metamask extensions, deploy testnet contracts or make smart contract calls.

JSON-RPC Mainnet (Free & Paid tiers)

For this version all free queries will be redirected to Arkhia's Mirror node, but for any writing calls (e.g. deploy a contract) no wallet is attached to the relay with real Hbars since Arkhia will not accommodate this cost.

Free version will have a shared service of 100 rps, not suitable for high performance/production.

Paid tier version will have dedicated bandwidth so requests will be with dedicated TPS per account

If you are interested in a Mainnet Prod ready Json-RPC Relay please contact us.

You can have a private JSON-RPC Relay hosted within our infrastructure with a custom configuration and a private wallet to accommodate any HBAR costs.
