How to make a view-only wallet
A view-only wallet is a special type of wallet that can only see incoming transactions. Since it doesn't hold your mnemonic seed and private spend key, it can't sign transactions and it can't see outgoing transactions. This makes them particularly interesting for
- Validate incoming transactions to cold wallets or hardware wallets
- Monitor incoming donations to a fundraising campaign
- Developers writing libraries to validate payments
View-only wallets cannot sign transactions, therefore they can't spend a balance alone. However, they can be used as part of an offline transaction signing, by creating unsigned transactions to be signed offline in a cold device, and later by sending the signed transaction to the network.
If your wallet has outgoing transactions, the balance displayed will not be correct. To get a correct balance in a view-only wallet, you have to import the accompanying key images of each output of the wallet.
You can also create a view-only wallet of a hardware wallet, however this kind of view-only wallet doesn't support offline transaction signing and importing of key images.
In order to create a view-only wallet, you must either have access to a wallet or know the main address and the private view key from a wallet.
