Monitoring blockchain addresses is a crucial capability for developers, investors, and businesses operating in the cryptocurrency space. Whether you're building a wallet application, tracking large transactions, or analyzing on-chain behavior, real-time address monitoring APIs provide the data infrastructure needed to stay ahead. This guide walks you through how to effectively use BTC, ETH, and TRX address monitoring APIs—with a focus on practical implementation, key features, and best practices.
The ability to receive instant notifications when a monitored address conducts a transaction—such as receiving or sending funds—empowers users to respond quickly to market movements, detect suspicious activity, or enhance user experience in decentralized applications (dApps). One such powerful tool enabling this functionality is the Tokenview Address Monitoring API, which supports Bitcoin (BTC), Ethereum (including all ERC20 tokens), and TRON (including all TRC20 tokens).
What Is Blockchain Address Monitoring?
Blockchain address monitoring refers to the process of tracking specific cryptocurrency addresses for on-chain activity. Whenever a transaction occurs—like a transfer of funds—the system detects it and triggers a notification. These alerts are typically sent via webhook, an HTTP callback that delivers structured data (usually in JSON format) to a predefined URL.
This functionality is especially valuable for:
- Wallet developers who want to notify users of incoming payments.
- Investors tracking whale movements or institutional inflows.
- Compliance teams monitoring suspicious transactions.
- dApp builders integrating real-time balance updates.

Step-by-Step Guide to Setting Up Address Monitoring
1. Register a Tokenview Developer Account
To get started with address monitoring, you’ll first need to register a developer account on Tokenview. This grants you access to their API ecosystem, including the address tracking service.
Visit the Tokenview API portal and sign up. Once registered, you’ll receive an API key, which authenticates your requests and enables secure communication between your server and Tokenview’s nodes.
This step is essential—without a valid API key, you won’t be able to configure webhooks or retrieve transaction data.
2. Configure Your Webhook URL
After logging into the Tokenview API dashboard, navigate to Address Track > Settings.
Here, you must set up a Webhook URL—this is the endpoint on your server where Tokenview will send transaction notifications. Ensure this URL is publicly accessible and capable of handling POST requests.
⚠️ Important: If the Webhook URL is missing or misconfigured, you won’t receive any alerts—even if transactions occur on monitored addresses.
Next, select the blockchain network (BTC, ETH, or TRX) and enter the address you wish to monitor. For example:
- To track USDT on Ethereum (ERC20), choose ETH.
- To track USDT on TRON (TRC20), choose TRX.
This flexibility makes the API ideal for multi-chain applications.

3. Add or Remove Monitored Addresses
Managing monitored addresses is straightforward through the Tokenview dashboard.
Under the Address Track section:
- Click Add to include new addresses.
- Select the chain and paste the wallet address.
- Confirm the addition.
All active monitors appear in the management interface, where you can also remove addresses at any time. There's no limit to how many addresses you can track, making it scalable for enterprise use.
Changes take effect immediately—once an address is added, the system begins scanning the blockchain for relevant transactions.
4. Receive and Verify Webhook Notifications
Once configured, the system automatically pushes transaction data whenever a monitored address interacts with the blockchain.
Each webhook delivers a JSON payload containing key details such as:
- Transaction hash
- Sender and receiver addresses
- Amount transferred
- Timestamp
- Token type (e.g., ETH vs USDT-ERC20)
- Block confirmation status
You can view these records directly in the API dashboard under Webhook History, or query them programmatically using the following endpoint:
https://services.tokenview.io/vipapi/monitor/webhookhistory/{coin}?page={number}&apikey=your_apikeyReplace {coin} with btc, eth, or trx, and {number} with the desired page number.
This allows for both manual review and automated integration into analytics platforms or alerting systems.

Frequently Asked Questions (FAQ)
How quickly are webhook notifications delivered?
Notifications are typically delivered within seconds after a transaction is confirmed on-chain. Delays may occur during network congestion but are rare under normal conditions.
Can I monitor smart contract interactions?
Yes. The API captures all incoming and outgoing transactions, including those triggered by smart contracts. However, internal calls (e.g., within a contract function) may require additional parsing depending on your use case.
Is there a rate limit on API usage?
Free-tier users may have limitations based on plan type. Enterprise users can request higher limits or dedicated node access for improved performance and reliability.
Do I need to run my own node?
No. Tokenview provides full node services across 120+ blockchains, eliminating the need for infrastructure setup or maintenance.
Can I track token balances over time?
While the API focuses on transaction alerts, you can combine it with balance-checking endpoints to build historical tracking dashboards.
Is my data secure?
Yes. All communications are encrypted via HTTPS, and your API key should be kept confidential to prevent unauthorized access.
