JSON-RPC Calls

When some platforms or frameworks don't have any quality web3 library or SDK, there's always the possibility to make the blockchain calls directly to the JSON-RPC methods supported by the chain.

Some of the JSON-RPC methods supported by SKALE chains are:

• eth_getBalance
• eth_blockNumber
• eth_getTransactionCount
• eth_sendTransaction
• eth_call

Implementation Example

Get Balance

import axios from 'axios';

const rpcEndpoint = 'YOUR SKALE RPC ENDPOINT';
const senderAddress = '0x...';


const requestData_balance = {
    jsonrpc: '2.0',
    method: 'eth_getBalance',
    params: [senderAddress, 'latest'],
    id: 1,
  };


async function JSON_RPC_CALL() {
    try {
        const response = await axios.post(rpcEndpoint,requestData_balance);
        return console.log(response.data);
      } catch (error) {
        console.error(error);
        return [[],[]];
      }
}

JSON_RPC_CALL();
