I've made a new wallet.dat after 0.13.0, I've got that backed up. What I meant is an additional physical backup - for example, writing down the master seed on paper and storing it in a bank safe.

Initially I planned to do the following:


* Unlock wallet.dat file
* Run "dumpprivkey" with the corresponding address
* Save the resulting private key on paper, laminate it and store in a safe

But unless I'm mistaken, the private key will only be for the specific address I used, meaning it doesn't provide a long-time backup for all possible addresses derived from the master key. Is my understanding correct? Can I get a physical backup that will give me the same type of backup the wallet.dat file gives me?

Hi all,

I want an additional backup to the wallet.dat file. I was thinking of dumping the private key and storing it on paper somewhere safe, but I understand that it will be invalidated after 100 transactions?

Is there a way to get the master seed for the HD wallet? Will "dumpwallet" show me the seed?

Ideally I want something that I can enter directly into Bitcoin Core to regain access to my addresses.


Thanks in advance!
