umbrel Hey umbrel, thanks! Was already working on a solution (making a list of exchanges addresses etc.) but will definitely implement yours asap! ?

    how to send XLM from the Black wallet to Bittrex correctly?

    I only see one way on the Black wallet application. When clicking the send button and entering the destination address, it only allows a merge account operation. I couldn't see any other way to send XLM out to the bittrex account.

    How to do it the right way??

    Black wallet not clear at all how to send XLM to an exchange properly....

      lemauve Your account must have at least 20 XLM on it to exist (this is true for all wallets) - blackwallet allows to "bypass" that limit with the merge_account operation which consists in merging the account's funds into another wallet.

      Sadly exchanges do not support that op.

      So in your case, you can only send Lumens to an exchange if you have more than 20 XLM and if (balance - amount) remains greater or equal to 20 XLM. This is a Stellar limitation.

      Please let me know if it's not clear enough - I will edit the merge account window to clarify that for users ?

      EDIT: Text updated, hope it's more clear for users now! Thanks for reporting that!

          This information you just posted should be in black wallet when a person clicks the "send" icon/link to transfer out XLM elsewhere. I could not figure this out when I was using Blackwallet.

              Added some security checks for payments to exchanges;

              • merge_account is disabled for exchanges
              • check that the memo is not empty

                orbit84 Thanks for doing this! We need more wallets with this functionality, especially that exchange addresses are well known.

                I think that the only missing feature now is Ledger integration.

                    bkolobara Yup! It'd be cool tho that exchanges start supporting both merge operation & federated addresses!

                      Please can someone help me...my Blackwallet has somehow been hacked I all my Lumens have been stolen!!
                      I did NOT initiate any transfer of any of my lumens from my wallet but somehow they have all been removed from my account...Please someone from Blackwallet help me out with this!! Is there ANYTHING you can do to look into this for me!
                      Please respond!

                        Kcdough Hello,

                        I am sorry to hear that, unfortunately there is not much I can do. Blackwallet is no more than an account-viewer, we do not store your private keys and never have access to your accounts/private keys or anything else.

                        Did you share your private key anywhere? The safest way to store your private key is to write it on a paper and put that paper somewhere safe.

                        I'll soon be working on a Ledger integration too.

                        Where were the lumens sent (address)? If the destination is an exchange, then the theft's identity can probably be found (by contacting the exchange/local authorities).

                            orbit84
                            Thank you for responding and please let me be totally clear so there is no confusion....NOBODY had my secret key. I am the only person that knew this account even existed. It was absolutely NEVER shared which is why I cannot understand how this has happened at all!

                            The public address it was sent to on Dec 11th at 11:36am was GCOBRXMLECEMECRAAIPUYJXVT2PMEYABEDSNQSVF4G67A5RDML7MO44Y
                            I don't know how to determine who/what this address is.

                            Nobody has access to my computer and I am just feeling completely robbed at this point!

                            Any insight into this on your end would be at least somewhat helpful....I do have another blackwallet that was not compromised which leads me to believe it was a breach from within Blackwallet itself (not thru my computer)! Is this possible and is there anyway it can be at least looked into on your end at all? Please let me know

                                Kcdough Hey,

                                Here you can see more about the destination: https://stellarchain.io/address/GCOBRXMLECEMECRAAIPUYJXVT2PMEYABEDSNQSVF4G67A5RDML7MO44Y

                                By following transactions over and over you get there:
                                => https://stellarchain.io/address/GAHK7EEG2WWHVKDNT4CEQFZGKF2LGDSW2IVM4S5DP42RBW3K6BTODB4A
                                => https://stellarchain.io/address/GCO2IP3MJNUOKS4PUDI4C7LGGMQDJGXG3COYX3WSB4HHNAHKYV5YL3VC
                                => https://stellarchain.io/address/GB6YPGW5JFMMP2QB2USQ33EUWTXVL4ZT5ITUNCY3YKVWOJPP57CANOF3 (Bittrex address)

                                It doesn't mean that all these addresses are owned by the same person, perhaps he sold the lumens, then someone exchanged them to bittrex etc.

                                Any insight into this on your end would be at least somewhat helpful....I do have another blackwallet that was not compromised which leads me to believe it was a breach from within Blackwallet itself (not thru my computer)!

                                As I said, blackwallet is only an account viewer and everything is stored on your machine - so your computer has probably be compromised or your key has been stolen. Blackwallet's code is public and non-obfuscated, you are free to read it.

                                Also if your second blackwallet's wallet was not compromised, it seems very unlikely that blackwallet is implied (otherwise both wallets would have been compromised I guess), so I think the attacker had your secret key...

                                    Well it looks like whoever this is is robbing people blind left and right....I have had a full diagnostic on my computer and nothing has been breached on my end....my key was only ever in my memory...never written down, never emailed, never given to anyone so looks like its a mystery on all fronts!! I am disheartened with this to say the least and I have lost faith in the whole crypto experience! Wish I had my lumens back as I lost a lot of my hard earned money! Lesson learned!

                                        Kcdough instead of losing faith in whole crypto experience invest $60 and buy yourself ledger nano to store private keys securely.

                                            You mean the one that i had ordered last week and was anxiously awaiting so I could tuck my lumens away safely...yeah I got it yesterday...a day late and many dollars short!

                                              Kcdough Pretty weird then - and the chances of someone generating the same secret key than your are infinitesimal so... In your case I agree with umbrel, it's maybe better for you to use the ledger!

                                                I conducted an investigation and here are some thoughts on your case.

                                                1. If you look into the effects of mentioned account (https://stellar.expert/explorer/account/GCOBRXMLECEMECRAAIPUYJXVT2PMEYABEDSNQSVF4G67A5RDML7MO44Y), you'll see that GCOB...O44Y is affiliated with account GAHK...DB4A. I guess that GBPH...L2XX is your account, from which 54,600 XLM were transferred to the intermediate account.
                                                2. GAHK...DB4A looks like a very active account with large amounts been transferred from exchanges. However, it's not a final destination itself. The account GCO2...L3VC seems to be the holder address.
                                                3. I googled both addresses, and found one mention of GAHK...DB4A here: https://www.mystellar.org/thread-49-post-37652.html#pid37652. Not sure if this "mitchisboss" is a real person or just a fake account, but that's at least something. You can send a PM to that guy.

                                                Hope you'll get your lumens back.

                                                  Thank you so much....I'm not sure you are affiliated with Blackwallet in any way but this is what I meant when I asked for ANY information would be helpful.
                                                  Doubtful I will ever get my lumens back at this point and am still completely unaware of how this even happened but I suppose it's a learning lesson for me. I have another Blackwallet account as well and promplty moved all my lumens off it in case the scumbags try and hit me twice!
                                                  Anyone know where I can get some free lumens! haha
                                                  Thanks Again and if anyone wants to take on the challenge of getting my lumens back I'll gladly give you 10,000 of them for the help!
