QuickNode Webhooks Events

Overview

Set up QuickNode Streams for real-time on-chain event processing with custom filters and webhook delivery.

Prerequisites

• QuickNode account with Streams access
• HTTPS webhook endpoint

Instructions

Step 1: Create a Stream via Dashboard

1. Dashboard > Streams > Create Stream
2. Select chain: Ethereum Mainnet
3. Filter: Contract events for specific address
4. Destination: Webhook URL
5. Set payload format: JSON

Step 2: Handle Stream Events

import express from 'express';

const app = express();
app.post('/webhooks/quicknode', express.json(), async (req, res) => {
  const events = req.body;
  for (const event of events) {
    console.log(`Block: ${event.blockNumber}`);
    console.log(`TX: ${event.transactionHash}`);
    console.log(`Topics: ${event.topics}`);
    // Process on-chain event
    await processBlockchainEvent(event);
  }
  res.status(200).json({ received: true });
});

Step 3: Filter by Contract Events

// Stream filter function (runs on QuickNode infrastructure)
 () {
   targetContract = ; 
   transferTopic = ;
  
   data..( {
     tx.?.(
      log..() === targetContract.() &&
      log.[] === transferTopic
    );
  });
}
