Title: Doubt about the deseed / reseed command Post by: dimasmjunior on April 02, 2013, 02:57:39 AM Hi guys,
The documentation for Electrum mentions that I can create an offline wallet: https://en.bitcoin.it/wiki/Electrum#Offline_wallet (https://en.bitcoin.it/wiki/Electrum#Offline_wallet). It says: Quote step 2: extract the seed from your wallet file: [offline]$ electrum -o -w wallet deseed This will remove the seed from 'wallet', and save it to a file named 'wallet.seed' This does not happen in the latest version. Instead only a file named electrum.dat.seedless is created. Without the wallet.seed it's impossible to 'reseed' a synced wallet and make offline transactions. Also the --help option does not mention any reseed command. Has things changed and the documentation is stale? Am I missing something? What is the correct way of doing this? Thanks in advance.

I have a totally offline computer which I installed Electrum on and generate my offline wallet seed. I exported this wallets Master Public Key through settings->export. I created a deseeded (read-only) wallet using the MPK on my online computer. Whenever I need to touch the funds in my offline wallet I first create a transaction from the deseeded wallet which I store on a usb drive. (You can do this by simply making a payment from "Send" tab it will save it as a file). I hook up the usb drive to my offline computer and use Electrum there to sign the transaction, after which I transfer it back to the online pc to broadcast it over the network.

Maybe Electrum' documentation need to be updated with the MPK option for offline and online wallets. Title: Re: Doubt about the deseed / reseed command Post by: ThomasV on April 04, 2013, 10:59:01 AM sorry, the documentation on the wiki is deprecated.
please use the doc included in the package: https://github.com/spesmilo/electrum/tree/master/docs Title: Re: Doubt about the deseed / reseed command Post by: dimasmjunior on April 08, 2013, 09:10:15 PM Thank you all. I'll try the updated documentation.
It would be very nice if electrum generated a file to make the process easier. Something like: Code: electrum maketx <addr> <value> unsigned.tx And then, on the offline node: Code: electrum signtx unsigned.tx signed.tx And finally: Code: electrum sendtx signed.tx I understand that using stream redirection can alleviate the problem on the final step, but the signing would still be very messy. It would be nice to have a simpler command line interface. Title: Re: Doubt about the deseed / reseed command Post by: btcven on April 08, 2013, 11:44:08 PM Thank you all.
