In the world of digital currencies, a watch-only wallet might sound unfamiliar to many investors, but for frequent users of cryptocurrency wallets, it's an incredibly useful feature. Essentially, a watch-only wallet allows you to monitor the asset overview of a specific address by importing its public address or domain. Think of it as a personalized blockchain explorer for tracking a particular wallet, but with one key difference: it must be used alongside a cold wallet to perform on-chain actions like transfers. You can even add multiple watch-only wallets within the same application for easier tracking. So, what exactly are the practical uses of a watch-only wallet? Let’s explore its functions in detail.
Core Functions of a Watch-Only Wallet
A watch-only wallet serves two primary purposes: monitoring the assets in a cold wallet and assisting in withdrawing or transferring those assets. Since cold wallets are offline storage devices not connected to the internet, initiating transactions requires an intermediary—this is where the watch-only wallet comes into play. If you need to transfer tokens from a cold wallet, the watch-only wallet initiates the transaction request, which then must be confirmed and signed by the cold wallet for security.
This setup ensures that the cold wallet remains completely offline, minimizing exposure to online threats. The watch-only wallet acts as a window into your cold storage, allowing you to check balances, review transaction history, and monitor overall asset distribution without risking the private keys. For instance, when you want to execute a transaction, the watch-only wallet generates a request, and the cold wallet signs it via QR code scanning—a seamless yet secure process.

Beyond security, watch-only wallets simplify portfolio management. Instead of juggling multiple blockchain explorers for different networks, you can view multi-chain asset distributions in one interface. This is especially valuable for investors holding diverse cryptocurrencies across various blockchains, as it streamlines tracking and reduces hassle.
How to Create a Watch-Only Wallet
Setting up a watch-only wallet is straightforward. Here’s a step-by-step guide using imToken as an example:
On a Connected (Online) Device:
- Open the imToken app and ensure you’ve completed initial setup and identity creation.
- Navigate to: Me → Manage Wallet → Add Wallet → Select ETH → Choose Cold Wallet.
- Use the scan function to capture the QR code displayed on your offline device. This imports the cold wallet address.
- Proceed to the authorization and signing interface.
On an Offline (Cold) Device:
- From the ETH wallet screen, select the scan option.
- Scan the QR code shown on your online device to receive transaction details.
- Enter your password to generate an authorization signature QR code.
Back to the Online Device:
- Scan the signature QR code from the offline device using the watch-only wallet interface.
- Confirm the action to complete the setup. Your watch-only wallet is now active and can display the cold wallet’s balance and transactions.
This process highlights how watch-only wallets enhance security by keeping private keys offline while enabling convenient monitoring. Unlike traditional blockchain explorers, they offer a unified view of assets across chains, making them a preferred tool for savvy investors.
