The word phrase is all you need, several tools can recreate the private keys.
What's important is to make sure you don't install a compromised version of Electrum, many scam sites try to trick people
This is not true. Electrum does not abide by bip39 which is the standard other wallets support @ tezza123 You will need the algorithm contained in the electrum source code to convert your seed to the individual address private keys. Backing up the private keys is not safe since electrum creates new ones as you use old addresses. You would have to keep backing up private keys each time you spent bitcoin. It would defeat the entire purpose of using a deterministic wallet. If you're worried about electrum disappearing I suggest you archive a copy of the software as well. |

Core addresses are not multisig by default. Those are p2sh segwit addresses. When importing in electrum you have to prepend p2wpkh-p2sh: to the private key. For example: To dump all the private keys use the dumpwallet command in core debug console. dumpwallet </path/to/somefile> . open that file in a text editor to see the priv keys. |

Yeah sorry I didn't mention that the site had to be loaded first. Kinda forgot  |

Edit: Actually you can use your browser's developer tools to decrypt the priv key. For example on firefox ctrl+shift+k should bring up the js console. There you can decrypt the priv key with the following code: var mencrypted = "enter encrypted priv key here";
var mpassword = "enter password here";
var decrypted = CryptoJS.AES.decrypt(mencrypted, mpassword);
alert(decrypted.toString(CryptoJS.enc.Utf8));

Wondering if there are any other vulerabilities besides the fake message between versions 3.0.6 - 3.3.4 which would prompt an upgrade? Looking at the notes, I don't see any severe bugs or vulnerabilites.
wallet file corruption and the phishing message one would apply to you. |

@BitMaxz ismine requires quotes for the argument you pass it. Actually an easier way is to simply ctrl+f to search the addresses on the addresses tab.

The first thing you need to do is answer the questions tryninja posed above. There is no point in using various proxies if you are on an old version of electrum that will never sync.

@adaseb as I told you above they changed the unsigned transaction format in version 3.2. So if you are using less than 3.2 on the cold wallet you won't be able to sign unsigned transactions created by a watch only version >=3.2.

If the address begins with bc1 then create a new non-segwit wallet as per this guide and use that instead. The reason you have to do this is because bech32 addresses are not yet supported by a lot of exchanges, ATMs and other wallets so receiving coins to them is problematic. |

I don't use any Segwit tranasctions however, because I assumed it wouldn't work in my cold storage software version.
Thanks for everybody that replied with the info. So far it looks like just a message I can ignore.
You may not use segwit but others may spend segwit outputs in your favour. For example exchanges. Old versions have trouble recognizing these outputs. If you don't intend to spend money from cold storage anytime soon then you don't have to upgrade the cold wallet (you should still keep the watch-only up to date). But you will have to update the cold wallet when you need to move your coins. |

See here for why you have many addresses |

Basically been a while since I've last used Electrum. And today for the first time I got the "white-hat" message saying that my version is Vulnerable and to please upgrade at the correct site pointed to: https://electrum.org/My question is what other vulnerabilites are there exactly besides the fake message when sending the transaction? I use cold storage and rather keep the older versions rather than upgrading both OS versions. Thank you You won't be able to do offline signing if you have the old version on your cold storage system. That's because with 3.2 they changed the unsigned transaction format. You haven't told us what version you are using? There were many bugs discovered in 2018. The json RPC one, a bug related to parsing segwit transactions, a wallet file corruption bug and of course the phishing message. The latter is just a message. It is harmless if you ignore it. If it won't let you spend your coins just switch servers. |

Thanks for both replies but company only paying SEPA or Card payment nothing else so I am afraid I am going to lost this amount.
Payoneer or bitwage are options for you: https://www.bitwage.com/for-individuals/Edit: SEPA is euro area bank transfers. If they are willing to do bank transfers then why not international wires via SWIFT? Ask them about it. It is unreasonable of them to expect a Pakistani to take euro area transfers since you are obviously not in europe. Note SEPA is very cheap but SWIFT costs significant sums. SWIFT payments of less than a $1000 are not really practical. Expect to lose $40-60 in bank fees. Bitcoin to Skrill and Skrill to Jazz Cash works fine as well (I know someone personally who does this all the time). However, JazzCash does have some low limits, and you'll also have to verify your Skrill account.
Is this cheaper than localbitcoins or is he doing it because he's not aware of localbitcoins? |

Any one have information about bitcoin related debit card which is working in Pakistan I need this very urgently as have some payment stuck which I can withdraw through only card.
I know of no such card. What sort of situation is this that you find yourself in? If you have bitcoin you can send it anywhere. You can sell on localbitcoins and receive money via bank, easypaisa, jazz cash etc. If you don't have bitcoin then try payoneer. It's a solution people use to get money from freelancing sites. Actually all media and including FMU itself, are referring to the same circulars issued by Sate Bank in April 2018.
Yes I agree SOB is not a law maker, and if we are doing clean business (no money laundering involved) we are good to go. After all Bitcoin is suppose to be all online and anonymous and we can avoid disclosing our personal or physical presence as much as we can...
The SBP is sowing FUD - fear, uncertainty and doubt because ATM they see this as the best way to deal with bitcoin. Apart from that the country has a history of banning new technologies so this just fits into the general backward mindedness of the people. At some point I do expect our law makers to legislate against bitcoin. It's guaranteed to happen because of our history. It's also guaranteed to be openly flouted like most laws in the country. |

Install electrum on your android phone. You can create a watch only wallet using your PC wallet's xpub. A watch only wallet lets you see transactions, addresses and balance but not spend your coins. It's like a readonly view of your PC's wallet. To create the watch-only wallet on your phone start with step 3 under "deterministic watch only wallet" in this guide. The screenshots are for the PC version but the steps are the same on android. In step 5 entering mpk you can simply use the camera on your phone to take a pic of the PC wallet's MPK QR code which you can find via wallet menu > information. If you're using a 2fa wallet on your PC (addresses start with 3) then the steps are a little different. In that case try this guide here to create a watch only version on your mobile. Once again the screenshots vary but the basic idea is the same. |

FIA itself is insecure about it's position on this matter because it is not illegal to buy and sell bitcoin in pakistan: https://propakistani.pk/2018/02/06/fia-recommends-govt-declare-bitcoins-illegal-pakistan/Also I suggest you visit localbitcoins and see for yourself. Trading carries on normally. No one is worried. BTW that last link you included from the FMU site does not call bitcoin illegal either. It is carefully worded to mislead you. Saying something is not legal tender is not the same thing as saying it is illegal. Legal tender has a specific meaning which I suggest you lookup. FYI even dollars, euros etc. are not legal tender in Pakistan. |

Excellent.. but be careful since crypto currencies and any trade in crypto currencies is still illegal in Pakistan.
Buying and selling cryptocurrencies is not illegal in Pakistan. Please don't spread lies shahzadafzal As of April 06, 2018 yes it's illegal, may be there is some new update. I'm not aware. Here is the official circular from SBP Prohibition of Dealing in Virtual Currencies/Tokens [ State Bank of Pakistan] April 06, 2018 http://www.sbp.org.pk/bprd/2018/C3.htmSBP prohibits financial sector from dealing in cryptocurrencies, says it will take action on violations. [ Dawn] April 07, 2018 https://www.dawn.com/news/1399997Pakistan bans cryptocurrencies. [ Express Tribune] April 06,2018 https://tribune.com.pk/story/1679446/2-pakistan-bans-cryptocurrencies/SBP doesn't make the laws in Pakistan. It can only prohibit financial institutions from touching crypto. In fact the SBP's ban is unconstitutional because one of the fundamental rights we enjoy is to be able to buy anything we like as long as it's legal. If we had decent sized exchanges they could have taken the SBP to court over the ban. Instead the only exchange we had folded overnight. In India they had large exchanges which took the matter to court and the government over there has had to re-evaluate their central bank's ban. |

You can convert extended keys using the Electrum cli now. For example: electrum convert_xkey xprv9zKZ5h5h2rxxvA3edftPEgJJUXTWgWHsJL4vqKH7nFxQqMRKVTH1LgPQefDNBizWi3uB7D3iBFbgh3AHmcg9CHjdq6FT8sngyw7R3RuJ2rk p2wpkh
Run `electrum help convert_xkey` for more info. You can't change the derivation path though. I wrote a script that lets you do that. It uses electrum functions for everything. Example: electrum getmasterprivate | xprv -m - -d "m/0'/0" -c pw2pkh -p
