def on_open(ws):
    subscribe_msg = {
        "jsonrpc": "2.0",
        "id": "1",

    ws.send(json.dumps(subscribe_msg))

ws = websocket.WebSocketApp("wss://api.hotstuff.trade/ws",
                          on_message=on_message,
                          on_open=on_open)

JavaScript

const ws = new WebSocket('wss://api.hotstuff.trade/ws');

ws.onopen = function() {
    const subscribeMsg = {
        "jsonrpc": "2.0",
        "id": "1",
        "method": "subscribe",
        "params": {

    ws.send(JSON.stringify(subscribeMsg));
};

ws.onmessage = function(event) {
    console.log('Received:', event.data);
};
