Has anyone had any issues withdrawing BTC??

Hello,
It seems like the "All In" button inside the "Sell Bitcoin" box doesn't work even though there's clearly a Bitcoin balance in my account. It completely ignores my clicking....
Thanks

Wow! Someone's trying to impersonate me? it should be 'arorts' not 'arrorts.'  Watch out! |

I do have Xcode and Brew. What should I do then? BTW, I'm also seeing people pointing out to python-trezor so that's yet another thing I'm trying to make sense out of it in addition to the Electrum plug-in for OS X.
Thx for your help.
I sucessfully installed Electrum 1.9.8 release from the github repo following the MacOSX instructions here https://electrum.org/download.htmlAs you already have xcode and brew installed I assume you are comfortable with the command line ! I haven't yet tried the latest master with the Trezor commits as I am still awaiting my classic first edition to reach me. https://github.com/spesmilo/electrum/commits/masterThis plugin https://github.com/m0mchil/electrum/blob/master/plugins/trezor.pyclearly requires python-trezor https://github.com/trezor/python-trezor/tree/master/trezorlibtry:
from trezorlib.client import types
from trezorlib.client import proto, BaseClient, ProtocolMixin
from trezorlib.qt.pinmatrix import PinMatrixWidget
from trezorlib.transport import ConnectionError
from trezorlib.transport_hid import HidTransport
TREZOR = True
except ImportError:
TREZOR = False The webbrowser plugin is completely different, you need it to setup your Trezor with myTrezor (unless you want to setup/restore your Trezor with the python tools) Are you referring to installing the Ubuntu's *Development version* and not the "Latest release" in that link? Does your install process for OS X create any .app entries as well in your Applications folder. I was able to get Electrum wallet to start via command line only but couldn't locate the .app/.dmg file that the github *Developer version* README file refers to. Does the python setup provide additional features not available in myTrezor (order of change address spending, freeze, etc?) In the long-run, I'd like to be able to restore access to all my private keys in the unlikely scenario Trezor completely ceases to exist or USB interface is discontinued. |

Could you please provide us with the installation steps for a Mac OS X? Linux steps in that path don't seem to work  Have you installed the Command Line Tools (or Xcode) and Brew ? I do have Xcode and Brew. What should I do then? BTW, I'm also seeing people pointing out to python-trezor so that's yet another thing I'm trying to make sense out of it in addition to the Electrum plug-in for OS X. Thx for your help. |

Anyone interested in getting some hosted Dragon miners at a discounted price (depending on how many you want), let me know and we can simply transfer ownership.
PM me for details :-).

can you advise how to do this? electrum does not seem to see the Trezor
It's in git master (not yet in stable release). Instructions for using development version are there: https://electrum.org/download.htmlThen there appear new wallet type "Trezor" on the wallet creation/restore dialog. Could you please provide us with the installation steps for a Mac OS X? Linux steps in that path don't seem to work |

Why are you using armory to begin with? If you want an offline cold wallet with watch-only compononet, Electrum is just as secure as Armory. Armory is only more secure on the online component, as it has the blockchain locally. But you seem to be wanting a light client. So Electrum sounds good for you, if you'd just use it normally.
First of all, my script is not cryptographically secure. I slapped it together so that hopefully it would generate your address. However, there is NO GUARANTEE that every private key listed will definitely correspond to the address listed. Be warned.
Also, the addresses being generated, even if you use Armory's paper backup seed, will NOT be the same as Armory. ALSO, if you decode the paper backup into hex and input it as a restore seed for electrum, you will get COMPLETELY DIFFERENT ADDRESSES from my script AND Armory.
So in summary, either switch to Electrum and send your bitcoins there, or just download the blockchain in Armory. Don't mix the two systems...
Yes, I'm definitely going to stick with a single Client wallet because you are right: otherwise I'd have to test sending out some mBTC to see if the private key is really working for that address but that'd be messy and tedious and dangerous. Is the blockchain.info wallet I was referring before also incompatible with Armory? If yes, then I'd do all in Electrum. But if it's compatible, I'd like to learn from you if that's viable alternative or I should forget about that, too. The only reason I'm leaning towards Armory is that in the unlikely event my offline PC crashes, I still can have a paper backup, which can be further split into 2 out of 3 paper sheets or electronic fragments required with a SecurePrint code, which is not even printed in the backup sheets to recover the seed. Electrum only has a phrase-based recovery method but that's about it. Thanks for your suggestions! |

Success!!!!  Thanks a lot!! Ok, so to summarize. I know that those two wallets are currently not compatible. However, if I do again exactly what I did before but derive the private key using the script you provided in an offline computer BEFORE I send any coins to its public address, I should be in good shape. I had requested Armory to create a light client but I believe they indicated some time ago that that goes against their security principles (someone might impersonate/hack the torrent/servers holding the blockchain , like the model Electrum does). Alternatively, I can create a watch-only wallet with Blockchain.info offline, dump the transaction history from sending address from bitcoinexplorer, run a local copy of Brainwallet HTML code in an offline computer to create and sign the transaction offline. And finally, I'll just broadcast it in blockchain.info. In this case, there would be no need to use Electrum at all. In the offline computer I can have Armory import the private key and back up all using paper backup method. This is the most secure and still light wallet model I can think of. Bye Bye Electrum... |

The instructions I gave have nothing to do with his master seed. They are for dumping address specific priv keys.
Edit: To clarify he is using the public key of an ordinary bitcoin address in his armory wallet. Not the armory MPK or anything like that. Just the pub key of an ordinary address. The instructions above are for getting the corresponding priv key and going from there.
Oh ok, I just downloaded Armory and I see what you mean now. > arorts I updated all the scripts and the exe to do what Abdussamad mentioned. Please follow his instructions to find the "PublicX" and "PublicY" that you used in Electrum... then just above it you will see "PrivHexBE" The new script will ask you for PrivHexBE and NOT the paper backup phrase. You will get your bitcoins back! yay! Here's the exe https://github.com/dabura667/help_arorts/releases/download/0.1/arms.exeHere's the scripts (use arms_mac.py if you're doing it on your mac) https://github.com/dabura667/help_arorts/archive/master.zipThanks all. So the publicX and publicY I used correspond to a **regular receiving address I created in Armory** , for which I do have its private key as well. I'm getting the feeling that I should have used Armory's root key/paper backup (2 text lines) when I created my Electrum wallet (after necessarily removing the "04" and using only the next 128 chars), is that correct? Will go ahead and use the updated scripts above...not before crossing my fingers. :-) |

Yes.
I would recommend running the exe on your offline Windows machine, though. If you run the script on your online Mac, then your offline Armory wallet's private keys have touched the internet.
From the sounds of it, you will restore all of your bitcoins. You only sent to one of the first addresses that was shown, correct?
Right now the script only generates 5 receiving addresses and 3 change addresses. This is the default number of keys shown for a new Electrum wallet.
I have explained how to run the script in Windows here, and on Mac via PM. Either way you choose, you should have the WIF private keys you need to recover your funds.
Let me know how it goes :-D
Unfortunately, I got a "Your MPK and the backup phrase MPK don't match" BTW, what I entered as the Master Public Key in Electrum was NOT a decoded version of Armory's root key/paper backup but a concatenation of PublicX and PublicY entries shown in Armory so I never saw any "04" prefix to even think to remove it. Any thoughts? Are the PublicX and PublicY values in hex format? Are each of them a 64 character string consisting only of 0-9a-f? Concatenated it should be a 128 character string consisting only of hex digits. Is that what you placed into electrum? Is that also what shows up in your Master Public Key area in Electrum? Electrum's MPK is just the Public x value and the Public Y value in 32 byte hex format concatenated. What exactly did you input into Electrum when creating the watch-only wallet? Perhaps could you PM me what you inputted and also what your Electrum is saying is the MPK? Yes to all your questions above. I just checked again and Armory's MPK is the same exact string as the MPK in Electrum. |

arorts hasn't replied but if anyone else is in this situation it's actually pretty simple to get the address specific private keys. git clone https://github.com/vbuterin/pybitcointools
pybtctool electrum_privkey <master private key in hex/wif> <number>
So if the "master private key" corresponding to the "master public key" used to create the watch only wallet is f45xxxx...xe3c and you want the private key for the first address in the wallet: pybtctool electrum_privkey f45xxxx...xe3c 0
If you need to convert between hex encoded private keys and WIF ones just use encode_privkey. So again: pybtctool electrum_privkey f45xxxx...xe3c 0 | pybtctool -s encode_privkey wif
You can then import that into whatever wallet you like. arorts had PMed me and I figured out his exact situation. 1. in armory, there is an ability to export the Master Public Key of the deterministic wallet. 2. He exported armory's MPK and used it to generate a watch-only wallet on Electrum. 3. He sent bitcoins to his watch-only wallet, and since there is no methodology in Electrum that directly allows use of the stretched Master Private Key... I basically slapped a script together that converts the Armory paper backup into the Master Private Key and does exactly what you said, except without any dependencies. (I had originally planned for him to copy/paste into an online python compiler or something... so I didn't want dependencies that weren't default contained in Python.) Anywho, there is an example case within arms.py (it's commented out, the Armory backup seed is on two lines, one without spaces just to make it easier to copy. and the MPK that corresponds.) Try compiling it, or just running the script in python directly. Any errors should show the error and pause (using raw_input() to wait for Enter to be pressed before closing)... also pressing enter after address gen closes as well. Hello everyone, I had to take some time off so I haven't recovered my coins yet. Just to make sure I follow the right process here are some clarifications: - My offline Armory wallet is a Windows one - My online Electrum wallet is in a Mac computer (latest OS X version) - The MPK I entered as the seedless Electrum wallet was exactly a concatenation of the 2 publicX and PublicY keys listed in Armory, NOT a decoded version of the paper backup/root key - I didn't remove any initial or ending characters before entering it in Electrum Having said that, what should be the right process that can be safely run offline? Seems like dabura667's last post? Thanks |

This thread is just wishful thinking so as to satisfy the desires of those who want to buy cheap. Hard to find evidence that it will go down (or up) in the short run. Let the market run its course irrespective of personal, unfulfilled speculations. Mining is an obsolete game at this point. What we need now is technology promotion and adoption so keep up the word of mouth so as to have more merchants tip the balance to attract more consumers.

Thanks. Unfortunately I'm not a developer. I have a very general idea of what that means but I'm not that advanced to any material degree to make any practical use of those concepts ... Is there any "priv key generator" webpage that allows me to plug in those values? (the last formula seems to imply that I'd need to try thousands of times until I get lucky and get the priv key that I'm looking?) I tried brainwallet but that doesn't seem to provide that functionality. This is sadly still very low level info for me to break it down |

I'm in a sort of a crisis. What's the best way to obtain the private keys of a "Receiving" address that appears in Electrum after creating a seedless/watch-only wallet with a Master Public Key. In addition to knowing that address I also know the following data generated in an Armory wallet with the same MPK: a) Root chain b) public key/address c) and its private key I have a bit of BTC that I had sent to that receiving address and can't take it out Please advise! Thanks, Sigh. A few clarifications: - Armory and electrum are two different wallets. They are mutually incompatible. - Watch only wallets don't have private keys - MPK stands for master public key. You can't derive a private key from a public key not even if it is a master public key. So now can you tell us what you are trying to do again? I'll definitely stop mixing the 2 systems as soon as I get my btc back. In the meantime.... (BTW, I don't have any offline Electurm wallet, just an offline Armory and an online, seedless Electrum one, which by nature can't do private key exports).. Really? Is there not any process to convert/translate those two wallets at all?? I read somewhere that with a Master Public key and a private key associated to a public key derived from it would allow me to obtain the Master Private Key. And that that Master Private key would help me get the private key I'm looking for. Is there such formula? Ok, I'm tipping 0.15 BTC to whoever provides me with a method that actually allows me to recover my BTC. If it exists... |

Thanks, can you just create an offline transaction and sign it to move the funds out of that address? better than to be exporting private keys, as private key+ MPK can expose your whole wallet. not sure why you're mixing electrum and armory???sounds like a mess. Thanks for the feedback. I did attempt to do that first but Armory simply doesn't understand the transaction format created by Electrum in their latest version and if you ask why Armory, it's because it has excellent security measures that I absolutely love. Why not Armory in my online wallet, too? I don't like to download a never-ending file that needs my PC to be online all the time. So it was absolute the perfect combination. Anyway...that was just a dummy account so I don't mind importing the private key to my online wallet as long as I quickly move the btc out of it. However, if I try to import the Armory private key (which belongs to a different address than the one I have my coins at), Electrum shows an import error regardless of whether I provide it in Base58 or the other format. Now why would that happen when I'm using exactly the same MPK (I concatenated Armory's PublicX and PublicY and entered them into Electrum) ? Is importing any private key of my offline wallet into Electrum the only solution? Is there any way I could add the Electrum "receiving" address into Armory without asking me its private key? At least I could connect it online to get the blockchain and move out the btc quickly. |

I created an unsigned transaction in Electrum with a watch-only wallet that had the same master public key than my offline Armory wallet.
The problem is that Armory doesn't let me sign it offline. It doesn't seem to understand the transaction format From Electrum.
What can I do? Is there any way to easily convert the transaction to a format that Armory can understand? and then viceversa to convert it to Electrum format or Blockchain.info format for broadcasting?
