ETCMCv2 Documentation

Public ETC RPC

ETCMCv2 runs a free, public JSON-RPC endpoint for Ethereum Classic mainnet. Use it in MetaMask, in dApps, or from any JSON-RPC client. Current health is reported on stats.etcmc.xyz.

https://rpc.etcmc.xyz

Adding it to MetaMask

1. Open MetaMask and go to Settings → Networks → Add network manually
2. Set New RPC URL to https://rpc.etcmc.xyz
3. Set Chain ID to 61 and Currency symbol to ETC
4. Save, then select the network

Example request

Any JSON-RPC method is sent as a POST with a JSON body:

curl -X POST https://rpc.etcmc.xyz \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'

Which returns the Ethereum Classic chain ID:

{"jsonrpc":"2.0","id":1,"result":"0x3d"}

The endpoint backs the ETCMCv2 mining pool at pool.etcmc.xyz — see the mining setup guide.

Excel & Google Sheets Integration

Get your node information directly in Excel or Google Sheets without using Telegram.

https://etcmc-monitor.org/api/nodes_info_excel?token=YOUR_TOKEN_HERE

For Excel Users

1. Open Excel
2. Go to Data → Get Data → From Web
3. Paste the API URL with your token
4. Click OK - your nodes will appear in a table

For Google Sheets Users

First, you need to create a custom function to import JSON data:

function IMPORTJSON(url) {
  var response = UrlFetchApp.fetch(url);
  var json = JSON.parse(response.getContentText());
  var headers = Object.keys(json[0]);
  var data = json.map(row => headers.map(header => row[header]));
  data.unshift(headers);
  return data;
}

Then in any cell, use this formula:

=IMPORTJSON("https://etcmc-monitor.org/api/nodes_info_excel?token=YOUR_TOKEN_HERE")

Your nodes will automatically appear in the sheet as a formatted table.

API Endpoints

Endpoints exposed by the local ETCMCv2 client web UI. Paths are relative to the address the client is listening on (port 5001 by default; the client falls back to another port if it is already in use).
