Getting Started

Json-RPC Relay allows you to use tools based on ethereum's JSON-RPC API to tap into the Hedera ecosystem. This documentation goes through the steps of setting up Arkhia's Json-RPC Relay thorugh popular ethereum based tools as well as direct API calls.

All examples below have been tested and verified using the available Json-Rpc release by Arkhia.

info

You will need:

• Arkhia JSON_RPC_URL
• Arkhia API_KEY

Both the URL and API KEY can be retrieved from the Arkhia Dashboard after you Create a Project.

Web3.js

import Web3 from 'web3';const HTTP_PROVIDER_URL_MAINNET = '<JSON_RPC_URL>/<YOUR_API_KEY>';const HTTP_PROVIDER_URL_TESTNET = '<JSON_RPC_URL>/<YOUR_API_KEY>';const web3Provider = new Web3(new Web3.providers.HttpProvider(HTTP_PROVIDER_URL_MAINNET), {    keepalive: true,    headers: [{ name: 'Access-Control-Allow-Origin', value: '*' }],    withCredentials: false});const getLiveness = async () => {    web3Provider.eth.net.isListening()        .then(() => console.log(`-> web3 provider is connected`))        .catch(e => console.log('-> web3 provider error: ' + e));}async function main() {    await getLiveness();}

Node.js (Axios)

import axios from 'axios';const data = JSON.stringify({  "jsonrpc": "2.0",  "method": "net_listening",  "params": [],  "id": 0});const config = {  method: 'post',  url: '<JSON_RPC_URL>/<YOUR_API_KEY>',  headers: {  'Content-Type': 'application/json'},  data : data};async function main() {    await axios(config)        .then(function (response) {          console.log(response.data));        });        .catch(function (error) {          console.log(error);        });}

Curl

curl --location --request POST '<JSON_RPC_URL>/<YOUR_API_KEY>' \--header 'Content-Type: application/json' \--data-raw '{    "jsonrpc": "2.0",    "method": "net_listening",    "params": [],    "id": 0}'
