Yes it's possible. If the sender didn't pay a good enough fee the transaction might have taken a long time to confirm.

Why don't you look up the transaction ID on a block explorer like blockchain.info to see when the transaction confirmed? You can find the tx id by right clicking on the transaction on the history tab and choosing to view details.

Why does the time of the transaction matter so much? If this is about tracking who sent you how much money the way to do that is to hand out different receive addresses to different people or organizations and make a note of it in your wallet out i.e. put a description on the receive tab and save it. This way you will know who sent you how much.

The timestamp is from the blockchain i.e. when the transaction was first incorporated in a block which is also called the first confirmation. The timestamp is from the block header which is added by the miner and may be up to two hours off from the actual time. So basically it's not very accurate.

Also I suggest looking at the history tab for transaction status and not the receive tab. The receive tab is just for getting addresses and setting a description for them at the same time.

Does it show up in your electrum wallet? If not then try looking up the transaction ID on blockchain.info to see what's up

A few long shot options for you to try are given below:

- Go to view menu > show console, switch to console tab and enter this to increase your receive address gap limit and generate more change addresses as well:


- Failing the above try restoring the second HD account of your wallet. Go to file > new/restore, enter a unique filename and click next. Proceed to restore your wallet from seed as before with one change - a new derivation path of m/44'/0'/1'  . Note the single quotes are not optional. Also you can always switch wallet files via file > open.

pending on the receive tab is meaningless. look at the history tab to see whether you received the money or not. also note that exchanges do withdrawals in batches so you may have to wait for the next batch to go out. just because it says processed or whatever on the site doesn't mean they've sent the coins out.

You know you can always ask the user to enter multiple addresses where the outputs will be sent? You don't have to resort to sharing private keys.

And BTW you talk about breaking the link. What about breaking the link with chipmixer? As long as they know your private keys they can steal from you. Today, tomorrow or 3 years from now!

That's probably related to the different wallet files issue that i talked about.


We all use exchanges to buy and sell bitcoin. We have to trust exchanges temporarily while they have our funds. Sometimes even that temporary risk bites us in the backsides when the exchange runs away with our money. Here you are asking the user to trust the service permanently i.e. even after you've "withdrawn" the funds.

The other thing is they are doing things the wrong way by sharing private keys. What else are they doing incorrectly? It is a basic mistake they are making and puts doubt on their entire service.

It was a mistake to trust this service. Any service that shares private keys as a mechanism to transfer bitcoin can't be trusted. He should do what he can now to secure his coins and the way to do that is to sweep them to an address whose private keys only he knows.

Also OP regarding your lost coins did you try switching wallets like I said? Each time you import you import to a different wallet file so your latest imported private keys are probably sitting in a different wallet file. Just go to file > open or file > recently open. You should still send those coins to an address in a new standard wallet though.

The sweep function in Electrum now redirects you to the send tab where you can set a fee of your choice.

If your default wallet is made of imported private keys then you need to create a new standard wallet. Here's a guide to do it properly. Then you simply use the sweep function to sweep any private keys to it.

The reason you do it like this is because knowledge of private keys is what determines ownership of bitcoin. You don't have exclusive knowledge of the chipmixer private keys. The owners of that site may also know the private keys. So you have to move the bitcoins to an address whose private keys only you control i.e. an address in the new electrum wallet you create.

The correct way to receive bitcoin is to have the sender send them to an address whose private keys only you know. Sharing private keys is not the way to transfer bitcoin because you don't have exclusive control and the sender can move the coins too.

I suggest going to file > recently open or file > open in case you imported the private keys into a different wallet. If you find the correct wallet I suggest creating a new standard wallet via file > new/restore and then sending your bitcoins to an address in that. This way only you will have the private keys that control the coins.

The wordlists are a part of the bip39 standard. They have to update the standard each time they add another language

If you look at check function here or bip39_is_checksum_valid in electrum you will see that the wordlist is used to verify the checksum.

In the case of Electrum's own seed mnemonics the seed version is encoded in the mnemonic and it serves as a checksum and as a way to identify the wallet type. You can see how electrum verifies it's own seeds here (on_restore_seed) and here (is_new_seed). As you can see the dictionary is not being used to verify the seed mnemonic. Only that it hashes to a number with the correct prefix i.e. a valid seed version.

If you want to use a custom wordlist with electrum see here. Note replacing the wordlist with your own will mean that Electrum can't verify bip39 seeds anymore.

The default worldlist is the same as the bip39 one but an interesting aspect of the electrum mnemonic algo is that it's not tied to any specific wordlist. You can use your own custom wordlist with it and restore wallets without supplying the wordlist used i.e. restore on any electrum installation.

It's in the wallet file.  use_change = false. You can add it using jq:

Electrum's seeds are not bip39 so this still doesn't apply to you.

When you use a hardware wallet the seed + any passphrase/extension are not shared with electrum. These are the secrets behind your bitcoins and they remain on your hardware wallet. So this doesn't affect you unless you restored your wallet from seed in electrum. Did you do that?

THE PROBLEM IS THAT YOU HAVEN'T PROVIDED ENOUGH DETAILS AND EXPECT US TO HELP YOU

Start by telling us what wallet software you were using?

you have to install the wallet on the offline device first in order to generate the master public key for the online wallet. see the guide here

It's already confirmed. If you don't see it in electrum you may want to restart electrum or switch servers. Failing that update to the latest version of electrum.

Well you have malware on that PC. It modified the wallet file and replaced the addresses with the malware author's. Your bitcoins are gone and nothing can be done to get them back. The only thing you can do now is to format the hard drive and reinstall the operating system. This is the only way to ensure that the malware doesn't cause you problems in future.

Sorry for your loss.
