Title: Using Bitcoin Core wallet to sign tx offline Post by: yan33 on November 07, 2016, 11:09:42 AM Hi,
I am using a Bitcoin Core wallet. I would like to migrate to a scheme where I can sign a tx offline on some setup and then use the online wallet to send it. Of course I know there are wallets that allow this, and I don't mind using them, but I would very much prefer that the wallet file itself remain the one I'm using in core. Is there a way to do this? Thanks! Title: Re: Using Bitcoin Core wallet to sign tx offline Post by: steven0021 on November 07, 2016, 11:21:42 AM You can already do it using signrawtransaction. If you're wondering how they should look like, check this page (https://en.bitcoin.it/wiki/Raw_Transactions#createrawtransaction_.5B.7B.22txid.22:txid.2C.22vout.22:n.7D.2C....5D_.7Baddress:amount.2C....7D). Or just enter either code in the console (Help > Debug window > Console).

It led me thinking of another question: If I want to generate a new change address, can that address be imported to a wallet running in pruned mode? (Or do I need to sync from scratch).

When you are pruned, you cannot import any private keys or addresses.It led me thinking of another question: If I want to generate a new change address, can that address be imported to a wallet running in pruned mode?

The idea behind offline wallets is that they have never been online. |
