eth_hashrate - Zetachain RPC Method

Get the legacy eth_hashrate compatibility value on Zetachain. Public endpoints may return `0x0` or an unsupported-method error depending on the client.

Returns the legacy eth_hashrate compatibility value on Zetachain. Depending on the client behind the endpoint, this call may return a hex quantity like 0x0 or a method-not-found style error.

Why Zetachain? Build on the universal omnichain blockchain enabling cross-chain smart contracts across 50+ chains including Bitcoin with native Bitcoin support, 50+ chain interoperability via UNISON, no bridging required, and partnerships with Curve and SushiSwap.

Note: Treat eth_hashrate as a node-local mining metric and compatibility value. Public endpoints often report 0x0 or reject the method entirely, so it is not a reliable chain-health or consensus signal.

When to Use This Method

eth_hashrate is relevant for cross-chain dApp developers, Bitcoin DeFi builders, and teams requiring native multi-chain interoperability:

  • Node Diagnostics — Check whether the connected client reports a legacy hashrate metric
  • Client Capability Checks — Distinguish between 0x0, unsupported-method, and method-not-found responses
  • Dashboard Integration — Display the metric alongside other node status data when it is available

Request Parameters

Request

This method accepts no parameters.

Response Body

Response
resultQUANTITY

Hexadecimal string representing the reported compatibility value when the client exposes the method

Code Examples

Bash
curl -X POST https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_hashrate",
    "params": [],
    "id": 1
  }'
JavaScript
// Using fetch
const response = await fetch('https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: '2.0',
    method: 'eth_hashrate',
    params: [],
    id: 1
  })
});

const payload = await response.json();
if (payload.error) {
  console.log('eth_hashrate unsupported:', payload.error.message);
} else {
  console.log('Zetachain hashrate:', parseInt(payload.result, 16), 'H/s');
}

// Using ethers.js
import { JsonRpcProvider } from 'ethers';

const provider = new JsonRpcProvider('https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY');
try {
  const hashrate = await provider.send('eth_hashrate', []);
  console.log('Zetachain hashrate:', parseInt(hashrate, 16), 'H/s');
} catch (error) {
  console.log('eth_hashrate unsupported:', error.message);
}
Python
import requests

def get_hashrate():
    response = requests.post(
        'https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY',
        json={

            'method': 'eth_hashrate',
            'params': [],
            'id': 1
        }
    )
    payload = response.json()
    if 'error' in payload:
        raise RuntimeError(payload['error']['message'])
    return int(payload['result'], 16)

hashrate = get_hashrate()
print(f'Zetachain hashrate: {hashrate} H/s')

# Using web3.py
from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY'))
try:
    print(f'Zetachain hashrate: {w3.eth.hashrate} H/s')
except Exception as exc:
    print(f'eth_hashrate unsupported: {exc}')
Go
package main

import (
    "context"
    "encoding/json"

    "github.com/ethereum/go-ethereum/rpc"
)

func main() {
    client, err := rpc.Dial("https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY")
    if err != nil {
        log.Fatal(err)
    }

    var result string
    err = client.CallContext(context.Background(), &result, "eth_hashrate")
    if err != nil {
        log.Println("eth_hashrate unsupported:", err)
        return
    }

    fmt.Printf("Zetachain hashrate: %s\n", result)
}

Common Use Cases

1. Compatibility-Aware Status Dashboard

Display the reported compatibility value alongside other client status signals without assuming the method is always available:

JavaScript
async function getMiningStats(provider) {
  const blockNumber = await provider.getBlockNumber();
  let hashrate = null;
  let supported = true;

  try {
    hashrate = await provider.send('eth_hashrate', []);
  } catch (error) {
    supported = false;
  }

  return {
    supported,
    hashrate: hashrate ? parseInt(hashrate, 16) : null,
    currentBlock: blockNumber
  };
}

2. Capability Check

Check whether the connected client reports eth_hashrate at all:

JavaScript
async function getHashrateStatus(provider) {
  try {
    const hashrate = await provider.send('eth_hashrate', []);
    return { supported: true, raw: hashrate, isZero: hashrate === '0x0' };
  } catch (error) {
    return { supported: false, message: error.message };
  }
}

console.log(await getHashrateStatus(provider));

Error Handling

Common errors and solutions:

Error CodeDescriptionSolution
-32603Internal errorNode may be initializing — retry after delay
-32601Method not foundNode client may not support this method
-32005Rate limit exceededReduce polling frequency

eth_mining

Check the legacy eth_mining compatibility method on Zetachain. Public endpoints often return a client-specific unsupported-method response instead of a boolean.

eth_coinbase

Check the legacy eth_coinbase compatibility method on Zetachain. Public endpoints may return an address, `unimplemented`, or another unsupported-method response depending on the client.
