Hello all,
I just had an update to the Android version of the Jaxx wallet.  Lost all my coins!  The default wallet address has been changed.  I download the Windows wallet and used 'restore' with the mnemonic for the Android wallet.  Guess what a new wallet address and no coins either. 

In other words, don't bother using this wallet!  They do not have their act together!

Sounds pretty hefty. A real unacceptable error in management of development of such app. Can't believe they tested it before. Well, they will sweat blood now I guess. Cheesy

Hope your loss wasn't too high.

Please ALWAYS contact me through bitcointalk pm before sending someone coins.

How much did you lose? I hope it wasn't too much. This is just another example not to use an untrusted wallet. Breadwallet and mycelium is there for phones already.

I sincerely hope that your loss wasn't too big.

But something still puzzles me... Why did you restore the wallet? And why didn't you made a Backup before the update? I guess you did something wrong and not the other way around...

And why didn't you made a Backup before the update?

Most Android apps perform auto-update.

Pretty sure the Jax wallet doesn't auto update the keyfiles. Something is fishy here.

I've been using Jaxx wallet since the first time I've run into any problems.

Could it be that you have the problem?

Are you sure of yours? Please ask for help from Jaxx before the final judgment is reached.

Another user had similar problems with jaxx wallet a while ago. The fix in the quote restored his coins. It involves installing mycelium's wallet on your phone and importing your jaxx wallet's seed into it.


There are similar complaints in this thread. This one reply says jaxx switches address automatically at certain time intervals, and often has problems syncing, so balances don't get displayed correctly. If that's true there's a chance your coins might still be accessible.

Don´t worry about the changed address. The address changes automatically at certain time intervals. Nevertheless, any previous address is still valid and can still be used.
I have just looked in my wallet: I am also missing some coins. But that´s not because the change of your adress. Jaxx currently must have a problem when retrieving the blockchain, so not all coins will be displayed. You can simply enter your t-address at Zchain11 and then you can see that all your coins are still there. Hopefully, Jaxx fixes the problem quickly!

Try importing your jaxx wallet's seed into mycelium's android wallet and see if your coins show up in it. According to this post the two wallets can use each others seed.

Jaxx follows BIP 32/39/44, so Copay (mobile and desktop) and Mycelium (Android, probably iOS) can restore the Bitcoin wallet from Jaxx.

This is the exact reason to download a desktop wallet and store them there.
Bitcoin Core is the one to use and nothing else.
Online wallets are for exchanges only.
Jaxxx has to many to choose from evena  browser wallet which I can see it being a disaster and to have your coins stolen quite easily. As I assume this is what has happened to your coins you claim the program has done in losing them.

They are actually well advertised by a lot of services and even Dash. How are people supposed to safely store coins if they have tons of altcoins? Jaxx isn't a web wallet. They let you control your private key. What do you consider a 3rd party application?

The real issue is that Jaxx is full of critical bugs that may end up making you lose your coins. But don't generalize all altcoins wallet because of jaxx's devs. Coinomi works very well and I never saw any issue while I was storing some coins for a while like DGB and Doge.


Jaxx does not support custom ERC20 tokens right now but they are working on it as far as i know.
That's not the real problem with their wallet. Their security is pretty bad and you can easily get hacked or lose your coins due to a bug.

Hmm first time I read a bad review about JAXX. But this just goes to show you gotta keep your own backups/seed/private keys. Whatever happens to any wallet, you can always import private keys and you're good.

I've been looking at Jaxx closer because of their weird "source control" view on their homepage seemed off and found this article that has turned me off of them: https://vxlabs.com/2017/06/10/extracting-the-jaxx-12-word-wallet-backup-phrase/

That is why official wallet of altcoin will be still a good choice to use unlike other wallet like jax anytime our coins will gone..
I heard many times issue about jax walelt and only newbie can say that jaxx wallet is good but the fact its not a good wallet anymore.. for safety use the official wallet if you are holding ethereum better to use official ethereum wallet instead ..

Jaxx either mobile or desktop should be avoided,thought its a cool app at 1st glance not until i was unable to send out funds for days,had to send out amount in random orders every min for like 3-4 days till i took all out.
Please avoid!

There was a news article about jaxx wallet users having their paraphrase used to access their wallet can be easily comprised.
I lost the article but when I find it I will post it for all to look at and be aware that it could happen to them as well.
If not taken care of with setting 2FA security on your wallet and this sort of thing or you can have your wallet comprised and the coins in there stolen as well.

Is this the article you are referring to? I have no intentions of using the Jaxx wallet unless that problem gets fixed. Too many people have lot coins already.

Reports are surfacing of a ‘vulnerability’ in Jaxx wallet leading to at least $400,000 customer funds being stolen.

A report on the insufficient wallet backup phrase storage methods this weekend has now updated to include reports that hackers are already exploiting the problem to steal cryptocurrency from users.



After you read the whole article[1], you will come up with the decision of not using this wallet again (most likely). Basically, they have no plans to alter or change the security setup of their wallet. I'd recommend everyone to either stop using this wallet or simply stop storing large amounts.

What do you mean by lost? Do you mean they were stolen by someone using the exploit I referred to earlier? If are they still in the same Jaxx address you sent them to then a technical problem might be stopping you accessing them. Some users found they couldn't see their coins in the Jaxx wallet but managed to retrieve them using various technical workarounds.

Does a block explorer still show you coins in the your Jaxx wallet address?

Jaxx sucks a lot. The older desktop versions were as slow as hell, my wallet froze constantly when I tried to scynch it, the newer version is a little bit better but still takes ages to sync.

You would expect to sync instantly like Myetherwallet, not sit and wait there 5 minutes. It's just a horrible experience for me.

The browser extension is nothing better, I had a hard time figuring out how to use it.

My experience with it was awful.
