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?

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!

thankyou for this good advice sir , may it help so many people out there like me , i wont use jaxx anymore , thanks alot sir

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.

mhhh can not say ive got bad experience till now, sync is fast and software (desktop) works how it should be.
the only thing is at the moment, they need till now more than 11 days to claim bch in the wallet and no end in sight. just waiting to get my btc splitted and there are just meager or no news on supportchannel. (https://www.reddit.com/r/jaxx/) also lot of people are waiting.

My experince with Jaxx was not always in a satisfactory manner, e.g. sometimes my balances didn't show correctly. But mostly I just had to wait a while, and next time everything looked fine again.

This serious threat is scary, but looking back to what we could have known before, see here:

If you look at the Jaxx Knowledge Base >Troubleshooting page you can read:

Quote from: Decentral
You can recover your wallet from the hard drive via a data retrieval service by locating your Jaxx Local_Storage files.

That means: The backdoor is intentional - maybe for selling the service.

Important:

The headline / thread title / subject is misleading. You are not only in danger while using the wallet. Your mnemonic can be stolen without having the wallet running, you only have to be connected to a network.

I have been playing with the desktop version of Jaxx for a couple of days. Very insecure..

Anyone with access to your computer can open it and see all your funds. The only thing protecting cleaning all the funds out is a 4-number pin, it seems like the pin can be bypassed, if not a 4 pin pass code is not that hard to crack.

I would not trust more then play money in Jaxx.

On the other hand - if your machine is being hacked, then game is over for more than your wallet. Of course everyone wants to keep their funds safe, so don't catch any spyware and just don't leave your device unattended.

Here's an article about it:

few wallets are more cheap in the market like that wallets do not buy and keep your coins. it can be hacked by few people so don't buy like that wallets. in the Google you have to search one best and good wallet next you have to buy it can keep your coins secure otherwise don't believe to any low class wallets.

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.
I personally use electrum wallet.
It gives me the feacher of 2fa verification before every withdraw.
But you are mentioning the core wallet here.
Could you please let us know how much secure the core wallet is?
Or how can we secure the core wallet?
Its also a bulky installation isn't it?

It may be possible that JAXX changed the standard derivation path for their wallet.
This would mean your keys still hold your bitcoins. You could try to import your seed into a different wallet (e.g. electrum)
and chose the most common derivation paths. That may lead to a "restore" of your right addresses and your funds.

Are you sure you downloaded the official version? And you did not have any other malware on your device?
JAXX has some known security flaws. But i'm not sure if JAXX stole your funds or some malware made use of those security holes.
Did you already scan your device for any kind of malware? In future i would advise to use mycelium on androids and electrum/core on desktop pc's.

I have had my coins stolen on Jaxx Wallet Last november 14th, after several attempts to withdraw my bitcoin.

On the 14th of november, I tried to send 0.1125982 BTC to another wallet of mine, but the transaction was never confirmed and instead of returning the full amount to my wallet,  I realized that two other transactions were made (NOT BY ME): one in the amount of 0.03649 and other in the amount of 0.0812808.

The first amount 0.03649 came back to the wallet but the second originated two other transactions: one in the amount of 0.00133863 BTC and other in the amount 0.04554556 and the amounts never came back to my wallet, despite of being present in the HISTORY of the wallet and the transactions I made are not in the HISTORY anymore.

I contacted Jaxx Support but they didn't respond any of the questions posted, neither gave me an answer to the stolen coins.

I have everything photographed and I am thinking of suing for money damages.

Anybody know what may have happened?

Got to be careful when using third-party wallets.

Make sure you save your passphrases and backup your private keys before you actually fund the addresses.

This way you can always import them in another wallet.

Try resetting your wallet's cache on Menu --> Settings --> Reset Jaxx cache.
You should also contact their support regarding this: https://decentral.zendesk.com/hc/en-us/requests/new

Meanwhile if you're in a hurry to access your funds, you can try importing it to myetherwallet [Please be careful on phishing links]
