Discord Alerts Tutorial

Want to get an alert in your Discord server whenever a physical coin moves?

Method 1: No-Code (Recommended)

Invite a free RSS bot like MonitoRSS to your server.
Use the dashboard command to add a new feed.
Paste our RSS URL: https://makerwatch.space/api/public/feed.xml
Done! The bot will post new transactions to your channel automatically.

Method 2: Custom Bot (Node.js Script)

If you prefer to host your own script, use this simple poller to forward events to a Discord Webhook.

const axios = require('axios');
const DISCORD_WEBHOOK_URL = 'YOUR_WEBHOOK_URL_HERE';
const API_URL = 'https://makerwatch.space/api/public/recent-events';

let lastProcessedTx = null;

async function checkEvents() {
    try {
        const res = await axios.get(API_URL);
        const events = res.data.data;
        
        // On first run, just set the benchmark
        if (!lastProcessedTx) {
            lastProcessedTx = events[0].tx_id;
            console.log("Initialized. Waiting for new events...");
            return;
        }

        // Check for new events since last processed
        const newEvents = [];
        for (let e of events) {
            if (e.tx_id === lastProcessedTx) break;
            newEvents.push(e);
        }

        if (newEvents.length > 0) {
            // Update benchmark
            lastProcessedTx = newEvents[0].tx_id;
            
            // Post to Discord
            for (let e of newEvents.reverse()) {
                await axios.post(DISCORD_WEBHOOK_URL, {
                    content: `🚨 **MOVEMENT DETECTED** 🚨\n**${e.maker}** - ${e.release_name} #${e.serial_num}\nType: ${e.type.toUpperCase()}\nAmount: ${e.amount_btc} BTC\nhttps://mempool.space/tx/${e.tx_id}`
                });
            }
        }
    } catch (err) { console.error("Poll Error", err.message); }
}

// Poll every 5 minutes
setInterval(checkEvents, 300000);
checkEvents();

Email & SMS Alerts

You can receive Email or SMS alerts without writing any code by using services like IFTTT or Zapier.

IFTTT: Create an Applet using "RSS Feed" as the trigger ("New feed item") and "Email" or "SMS" as the action.
Zapier: Create a Zap with "RSS by Zapier" as the trigger and your preferred notification method as the action.
