So I have set up a wallet on my offline computer. I have the master public key on my online computer in a txt file via usb. I already have my default online wallet with coins in it. How can I create my watch-only wallet on the online computer from the master public key? Because the GUI seems to be not making sense as I said. Thanks much!
It's very simple. You were almost there but try it again:
- Run electrum
- Choose File -> Create/Restore
- In the file selection dialog box enter a new file name say xyz.watchonly and click on save
- Select restore wallet from master public key
- Enter the MPK and follow the rest of the steps.
When you want to open the watch only wallet use the file > open menu or create a shortcut with this target:
electrum -w c:\path\to\xyz.watchonly
