Eidoo has implemented a feature that enables the import of a wallet in “watch only” mode and allows the user to visualize on the app any wallet they desire. It will be also possible to surf the browser and connect the wallet to DApps, but obviously, the user importing someone else's wallet in watch only mode, will not be able to approve and initialize any kind of transaction (because of the missing private key).
This feature is useful for example to see how it feels to be a whale, or to monitor a wallet, or to check NFT collections, or keep an eye on your cold storage without the risk of losing funds for being hacked.
To test it out, open the app, then, in the crypto homepage, tap on the icon on the top left corner of the screen, the one representing your account (1). Here, you will see your current accounts and the settings available to create or import new ones. Click on "Import account" (2), then choose "Watch only" and continue (3). Here is where you can either write an address or an ENS, or scan the QR code redirecting to one (4).
Remember, you can check anything you like of the imported account, but you cannot approve transactions of any kind (5).
