follow this video to restore your multibit HD wallet in electrum: https://www.youtube.com/watch?v=E-KcY6KUVnY&feature=youtu.be

file menu > save copy

btw you can use the above for HD wallets too.

Please ignore the other guy. Your addresses can't possibly be the same because according to the OP your electrum wallet is a multisig wallet between electrum generated seed and coinbase's extended public key. Coinbase knows nothing of your electrum wallet so the addresses can't possibly be the same.

What you need to do is create a new wallet like this:

file new/restore > enter name for your new wallet, click next,

select multisig wallet, next

from 2 require 2, next

select "i already have a seed", next

enter your seed from your electrum wallet, next, next,

select  " enter cosigner key", next

now past the xprv for the user key from coinbase. the xprv is the master private key or extended private key not the extended public key. it has to be the xprv of the User key in your coinbase wallet because it that key's public component that you used. if there is no option to get the extended private key then you are in trouble

after that you just click next next until you are done creating the wallet.


So once again you need the extended private key (xprv) of the User from your coinbase wallet. If you can't figure out how to get that then you can't be helped.

what do you mean 5/10? If it's a 2 of 2 multisig wallet then it should 1/2 not 5/10.

which coinbase multisig vault key did you use? Was it the one labelled shared key or user key in the graphic here:

https://www.coinbase.com/multisig?locale=en-US

If it's the shared or user key then you can just create a new multisig wallet with that xprv and the seed that electrum generated for you. Use file > new/restore to begin the process.

Test transaction is unnecessary. Bitcoin addresses have checksums in them so electrum will refuse to send coins to an invalid address. OTOH addresses don't have to be registered with any central authority so there is never any check as to whether the address is controlled by anybody or not. Bottom line being that test transactions make no sense. Instead to confirm your control over the target address sign and then verify a message with its private key. Right click on the address in the seeded wallet (on the offline machine) and you will see the option to sign/verify messages with its private key.

the menu bar should be at the top of the screen. tools menu. I can find it in my linux version of 2.9.3 so it should be there in macosx version too. you did download electrum from electrum.org right?

maybe it's  due to different characters used for line endings. run the file through dos2unix beforehand. maybe that'll fix it.

Seed words are never sent to electrum servers even if had you created an online wallet instead. The seed words are private information that you alone know. If anyone else got their hands on them they could steal your money.

Electrum is not a bank. Bitcoin is a peer to peer currency. There is no central registration authority or gatekeeper whose permission you need to get.

Bitcoin transactions are recorded in an open ledger called the blockchain. This ledger is secured by cryptography. Your transaction is simply recorded in this ledger as paying out x amount of coins to y address. Whether y address is in your control, somebody elses control or nobodies control isn't relevant at the time the transaction is recorded. That will only be tested when you go to spend your bitcoins. At that point in time you will have to sign the spending transaction with the address-specific private key which is derived from your seed words.

Anyway to answer your question about how do you know whether you own the coins or not. Two things. 1. look up the balance of your address on a blockexplorer like blockchain.info. 2. Open your wallet in tails, bring the addresses tab into view with ctrl+a, right click on the address with the coins and choose sign/verify message. Sign any arbitrary message and then verify the signature. If you can generate a valid signature for the address with the coins then you own those coins.

you should pay attention to the wallet balance not the balance of individual addresses. the wallet balance is displayed in the bottom left of the electrum window.

what you are seeing here is change being sent to change addresses in your wallet. you can confirm that these addresses belong to your wallet by looking at the transaction details. Change addresses are highlighted in yellow while other addresses belonging to your wallet are in green.

you can't spend from watch-only wallets and besides this is the elecrum forum not blockchain.info forum.

Are you using btc-e to get exchange rates? BTC-E died you know? What it means is that the exchange you are using to get EUR/BTC rates from is down. So look under woocommerce > settings > checkout > bitcoin. See what options there are there.

Search the forums. This question has been asked before.

That's an old version. Install the latest version and try again.

It's not a bip39 wallet so why choose that option? bip39 didn't even exist back then! I suggest restoring in 1.8, grabbing your private keys and saving them, installing the latest version of electrum, creating a new deterministic wallet and sweeping your keys to it:

You can sweep it if you like:

To import it you need to create a new wallet for it:

https://bitcoinelectrum.com/importing-your-private-keys-into-electrum/

you can only do this in an HD wallet. you can't do it in a wallet made from imported private keys.

i just tried it and it works on my hd testnet wallet.

It has been mentioned before on this forum. The solution is to create a new wallet and move your bitcoins to it.


not an arbitrary limit or anything hardcoded in the code. it's just that it gets slow when you have lots of addresses and/or transactions.

you can't do what you are trying to do with electrum. offline signing with imported private keys is not going to work. at least not via the GUI

The wallet files are stored separately and not removed when you uninstall electrum (the risk of funds losses is too great for it to remove the wallet files too).

You don't need to uninstall and reinstall to create a new wallet. Just use file  menu > new/restore to begin the process.
