I’ve got one wallet.dat from my laptop and another on my desktop, each containing various (different) receiving addresses that I use pretty often. I’d like to merge them into a single wallet.dat so I can see all my balances in one place.
If there isn’t some piece of software that can truly “merge” the two, is there some way to at least export an address/keypair from one wallet and then import it into the other?
Pywallet is a python script that (among a number of other things) can export and import key pairs. It’s not as complicated to use as it might sound, some python stuff has to be installed but that’s almost automatic and once it is done the tasks can be performed using a web interface.
