Not all wallets need to hold funds; some are used for tracking purposes. This test involves creating a “watch-only” wallet by entering a public address without its corresponding private key. The user should be able to add this address to their wallet view, allowing them to monitor its balance and transaction history. This is useful for tracking holdings on a cold wallet or observing a fund’s activity without having the ability to move assets. The watch-only wallet should display all the same information as a standard wallet—balances, tokens, NFTs, and transaction history—but any attempt to send funds from it should be disabled or result in an obvious error explaining that it is a watch-only address. This feature supports a hierarchical portfolio management strategy. The ability to track addresses without compromising their security is a valuable feature for advanced users, and its setup is detailed in guides found at metamask. The test is successful if the watch-only address is added and its activity is displayed correctly, with no functionality for spending funds.
