Topic: [ESHOP launched] Trezor: Bitcoin hardware wallet - page 136. (Read 966173 times)

In general, if this happen, you lost your coins for good. There is no other way, how you can recover or extract your coins back. Just make two copies of your recovery seed and store them on two different safe places and you should be fine.

Note: This is an if situation.

In the unlikely event that my Trezor breaks and I also lose my recovery seed what can I do? Is there memory on the Trezor that I could somehow extract to get my coins back or something?

Really, with all the respect, you don't need TXID, you just need that address you sent the bitcoins to, and put it in the search field. If you were able to send the transaction again from different client you provably must had known the address, so you could check if the prior transaction went through or not.

What happens is your Trezor gives xpub to myTrezor web wallet and the wallet asks backend BoP server for all your transactions. The one you don't see is missing in the list provided by BoP. It is clearly there when visible both on blockchain.info and on btcreceive. I assume there is some glitch in BoP, which is unfortunate, but there are three things that can happen:
1. Issue fixes itself when BoP is restarted.
2. BoP developer fixes the issue if you report it to satoshi labs.
3. BoP will find your transaction without doing anything. Have you tried "Forget device" and replug?

Concerning "recovering" the BTC: If you had more choices of wallet software then you could use any of those and there is high probability you would not see the same glitch you see now. If myTrezor does not see the transaction then Electrum probably would, because it uses completely different stack. You should not be worried about your funds, because you can always recover them using other software that is being developed and will be here soon. But there is some risk you will be blocked and need to wait until the bug is fixed / infrastructure is there.

Sweet, hopefully mine's close then

Ok I tested out your theory. I went back and used up every single address before m/0/44. My trezor is still showing the incorrect balance by 0.01btc. The balance on BTCReceive is showing correctly. So I'm guessing the only way to recover this lost btc would be to restore my seed to wallet32 app then send it somewhere else? I hope this is not the case.

yeah and this is what it says:

1CVHky4FZ4V5TN7DZSgaqwszRWg7iPrQfc (0.0001 BTC)

On myTrezor can you just look at your "used addresses"

Click Account -> Receive -> find and click the "Show used" link

I did actually receive a transaction with that address. One thing that I also noticed. when I go to the receive tab on mytrezor.com the addresses that are now available are only m/0/45 and up. If I want to send to the previous addresses, I would have to use btcreceive or bip32.org to generate the earlier addresses. I will try to send some small amounts to the earlier addresses to see if my lost transaction catches up.

The answer you seek is just a few posts back:

1) Your coins are not lost
2) If you have a gap of more than 20 unused addresses your balance will not be correct until you use some of the unused addresses
3) Since the balance calculating algorithm stops after it sees 20 unused addresses all you need to do is send some coins to the unused addresses between your last properly summed address and the "lost" one in such a way as to make sure there are not more than 19 unused addresses between any two addresses that contain BTC

Yes I can't confirm a transaction on the blockchain, when A) you don't have the TXID and B) it is group address that doesn't do refunds.

$100 is not a big deal to me, but still it is wasted money.

That is what I think I am going to do.   If I somehow lose or break mine, or have some sort of a hardware failure, i don't want to have to order another one and then wait all that time to get up and running again.   I know that I can load my seed into a different wallet, but still, I would feel more comfortable having another trezor on deck in case I run into any issues.

I have a missing transaction. Here is what I did right before:

 I installed the btcreceive app onto my android. I then loaded the xpub code into the btcreceive app. Then I proceeded to test the app sending multiple transactions to the keys generated on the app. Then I opened the account tab on btcreceive and tried sending to some of the addresses there. All was well until I tried one of the addresses further down on the list in the account tab. I tried the m/0/44 address. I sent a total of 0.01btc. this transaction is showing up in the btcreceive app, but it doesnt show up on the mytrezor.com transaction list. So I tried to send another small amount from another wallet to this address again and this transaction is showing up. Both transactions are showing up on blockchain.info.
https://blockchain.info/address/1CVHky4FZ4V5TN7DZSgaqwszRWg7iPrQfc. This has got me a little worried. What would happen if i had sent a larger amount of bitcoin? Would it be lost forever?

I'll buy a spare black one as a backup I think.

After much trial and error I finally figured out how to use http://bip32.org to verify the Bitcoin addresses being displayed at https://mytrezor.com against a second system (to make sure they are not being spoofed).

I thought I would post my findings here in case anyone else is struggling with this:

1) Open up https://mytrezor.com and copy the xpub key you want to verify against the output of the http://bip32.org web site.  Your xpub key(s) can be found under the advanced details on the main/home page for your wallet.

2) Open up the http://bip32.org web site and go to the second tab "BIP32 key".

3) Paste the xpub key into the BIP32 Extended Key box.

4) In the key info notice the depth number.  It should be 3.  Evidently this means that the key already includes the first three levels m/44'/0'/0' so you only need to add pathing past that point (see the next steps below).

5) In the Derivation Path drop down select "custom".

6) In the Custom Path box type m/0/0

Down at the bottom of the screen you should see a Bitcoin address.  It should match the first Bitcoin address from the Trezor!

7) Change the Custom Path box to m/0/1 and on the myTrezor press "More Please" and you should see that your second address matches, etc.

Once you get this far, if you want to know the change addresses used by your Tezor, change the Custom Path box to m/1/0, m/1/1, m/1/2, etc. and this will display the change addresses.

This guy get's it!

ON a happier note I received my second white trezor today, pleased to report the screen lamination issue is not present here, the screen seems brighter as well, I really think I just got one out of a bad batch on my first order, its completely night and day quality wise.

Second note, how a wallet handles change addresses, is built into the wallet architecture, it doesn't show them to you, as it's akin to having a change tray that counts when you throw a penny into it.....who cares, its there right?!?! That is all that matters.

Do a watch only wallet, on a single address, and resend bulks of funds to said address, anonymity lost my bum, where are Roger Ver's bitcoin? Anyone......Anyone.....Bueller?


Lastly, I do want a black trezor, like....yesterday. The white picks up every little smudge and smidge.

You don't know how to confirm a transaction on the blockchain?
Maybe you should learn before you use

You did not read the post right above yours where I said:

It looks like mytrezor got fixed, but the transaction that was stuck in my wallet, did get sent and I already sent it from different wallet, so I am out a $100. UGH

I will be updating my negative trust rating feedback accordingly.

> Wallet32 shows you the change addresses also.  If you want this feature just send a feature request to them.
I think there better to use BTCReceive from same author
As i know for Wallet32 you need to import there private seed (i don't have Wallet32 right now - may be i make mistake)
But BTCReceive undetstands xpub keys of accounts. The xpub keys of accounts can be found in mytrezor.com advanced options for each account.
But there bad news - BTCReceive now works only with one account and there no way to delete account Only uninstall + install again BTCReceive.
If you will want to import to Wallet32 you private key (seed) for viewing of change addresses so why you need the Trezor?
