Ethereum Wallet Tracker: Monitor Transactions in Real Time

·

Track Ethereum Wallet Activity with Automated Notifications

Stay informed about your Ethereum wallet transactions with a powerful, customizable tracking bot designed for both individual users and developers. The Ethereum Wallet Tracker monitors specified wallet addresses and sends instant notifications whenever new transactions occur—whether they’re standard transfers, internal calls, or token interactions (ERC-20 and ERC-721). Notifications can be delivered via Line Notify or Discord, making it easy to stay updated across platforms.

This open-source tool supports both the Ethereum mainnet and the Goerli testnet, ideal for developers testing dApps or managing smart contracts. Built with automation and security in mind, the tracker uses reliable APIs from Etherscan and Alchemy to ensure accurate, real-time monitoring.

How to Set Up the Ethereum Wallet Tracker

Step-by-Step Self-Hosting Guide

You can easily host the Ethereum Wallet Tracker on your own machine. Follow these steps to get started:

  1. Download the latest release from the GitHub releases page.
  2. Extract the ZIP file and open the config.yml file using a text editor like Notepad++.
  3. Fill in required credentials such as API keys and webhook URLs (details below).
  4. Run WalletTracker.exe to launch the application.
  5. Add your Line Bot or Line Notify as a friend to receive messages.
  6. Start monitoring—you’ll now receive alerts for every new transaction.
🔐 Always keep your API keys and tokens secure. Never share them publicly or commit them to version control.

Configuring config.yml: Essential Settings

The config.yml file is the core configuration for the tracker. Below is a breakdown of each field:

# Webhook URL must start with https:// and end without a trailing slash
webhook_url: ''

# Port the webhook listens on (default: 5000)
webhook_port: 5000

# Required API keys
etherscan_api_key: ''
alchemy_api_key: ''
alchemy_webhook_auth_token: ''

# Line integration
line_channel_access_token: ''
line_channel_secret: ''
line_notify_id: ''
line_notify_secret: ''

Each value corresponds to services you’ll set up in the following sections.

Understanding Webhooks and How to Set One Up

A webhook is an HTTP callback: a way for one service to send real-time data to another. In this case, it allows Line and Discord to send event data to your tracker.

Since most home networks don’t have public HTTPS endpoints, you'll need a reverse proxy. The easiest solution is ngrok, which provides a secure public URL for your local server.

👉 Learn how ngrok-powered tools streamline blockchain development workflows.

Using Ngrok to Create a Secure HTTPS Endpoint

  1. Sign up at ngrok.com and download the executable.
  2. From the dashboard, create a new domain (e.g., your-name.ngrok-free.app).
  3. Run ngrok config edit and replace the content with:
authtoken: YOUR_AUTHTOKEN
version: 2
tunnels:
  app:
    proto: http
    hostname: your-name.ngrok-free.app
    addr: 127.0.0.1:5000
  1. Start the tunnel with ngrok start app.
  2. Copy the generated HTTPS URL—it’s now your webhook_url.

This URL will route external messages (from Line/Discord) to your local bot securely.

Required API Keys and How to Obtain Them

Get Your Etherscan API Key

Etherscan provides blockchain data access:

  1. Go to etherscan.io/myapikey and sign up.
  2. Log in and click + Add.
  3. Name your app (e.g., “ETH Wallet Tracker”) and generate the key.
  4. Copy the API key into etherscan_api_key.

Retrieve Alchemy Webhook Auth Token

Alchemy powers real-time event tracking:

  1. Visit dashboard.alchemyapi.io/webhooks and sign in.
  2. Click on Auth token in the top-right corner.
  3. Copy the token into alchemy_webhook_auth_token.
💡 You can also use Alchemy’s API key if needed for additional features.

Integrating with Line Services

Set Up Line Channel Access Token & Secret

To enable messaging through Line:

  1. Go to Line Developers Console.
  2. Create a Provider and a Messaging API channel.
  3. In Basic Settings, find your channel_secret.
  4. In Message API, click Issue to get your channel_access_token.

✅ Ensure these settings:

Configure Line Webhook

  1. In the same console, go to Messaging API > Webhook URL.
  2. Enter your ngrok URL + /callback (e.g., https://your-name.ngrok-free.app/callback).
  3. Enable Use webhook.
  4. Save changes.
🔒 Line requires HTTPS—ngrok ensures compliance.

Get Line Notify Client ID & Secret

For push-style notifications:

  1. Visit notify-bot.line.me/my/services.
  2. Click Add Service, name it “ETH Wallet Tracker”.
  3. Set Callback URL to your webhook + /notify.
  4. After creation, copy the Client ID and Secret.

Users must authorize the service to receive alerts.

Adding Discord Bot Support

Although not detailed in the original config, Discord integration enhances accessibility.

Create a Discord Bot

  1. Go to Discord Developer Portal.
  2. Click New Application, name it (e.g., “WalletTracker Bot”).
  3. Under Bot, click Add Bot.

  4. Enable privileged intents:

    • Presence Intent
    • Server Members Intent
    • Message Content Intent
  5. Copy the token under Build-A-Bot section.

Use this token in your backend logic or extended scripts for message delivery.

Frequently Asked Questions (FAQ)

Q: Is the Ethereum Wallet Tracker free to use?

Yes, the tool is completely free and open-source under the MIT License. You only need to cover costs for third-party services like ngrok (if using custom domains) or API rate limits.

Q: Can I track multiple wallets at once?

Yes! The bot supports monitoring multiple Ethereum addresses simultaneously. Simply extend the tracking list in your configuration or database layer if customizing the code.

Q: Does it support ERC-721 (NFT) transactions?

Absolutely. The tracker detects ERC-20 token transfers and ERC-721 NFT transactions, including mints, sales, and transfers.

Q: What networks are supported?

Currently supports:

Future updates may include Sepolia or other testnets.

Q: Is my wallet data secure?

Yes. All tracking occurs off-chain via public APIs—you never expose private keys. Your wallet address is publicly visible on-chain anyway; this tool just adds alerting.

Q: Can I deploy this on a VPS?

Yes, deploying on a Linux VPS (like Ubuntu + systemd) is possible and more stable than local hosting. Use tools like PM2 or Docker for long-term uptime.
