Failing to add zpub key to watch only wallet (x-post from /r/Bitcoin)

10-12 08:24 - 'Failing to add zpub key to watch only wallet' (self.Bitcoin) by /u/Immediate-Host removed from /r/Bitcoin within 672-682min

'''
UPDATE: This has been an issue with Sentinel, everything is working fine again!
u/SamouraiWallet u/SamouraiWalletDev u/yilmzfurkan
This had me panicking yesterday evening since Sentinel displayed my balance as 0. Copied my public keys all over the place to test it with other apps, please let us know in thus sub next time!
Used sentinel for over a month to monitor my balance using the master public key shown of my cold card in Electrum.
Worked fine but just today it failed to load my balance, and kept loading forever, so I reinstalled the app, opened my electrum wallet (skeleton wallet, generated on cold card)
and when I used the information option to display my master pub key it displayed my zpub key, I used the qr code option but sentinel fails to add it and the mobile electrum wallet won't let me use it as well...

Used it for a month just fine before.... Really worried now that something is wrong with my keys. What could be the issue, why does no wallet let me monitor my zpub key all of sudden?
Electrum is still showing my correct balance though....

Private watch only wallet? (x-post from /r/Bitcoin)

submitted by ASICmachine to CryptoCurrencyClassic [link] [comments]

Xpub from Ledger Live does not create watching-only wallet of Ledger bitcoin account on phone.

I got the xpub for the bitcoin account on my Ledger Nano S and created a watching-only wallet on my phone. The Ledger has bitcoin in the account but the watching-only wallet doesn't have any bitcoin, transactions, and the addresses are all different (bc1... addresses on Ledger and 1... on phone). What happened?

How to add a Trezor wallet to Bitcoin Core as watch-only

I wanted to use Bitcoin Core to keep an eye on transactions (basically using your own full Bitcoin node to validate, instead of "trusting" Satoshilabs and their webwallet). This doesn't mean there's anything wrong with Satoshilabls' trezor web wallet - it's just a matter of being totally sovereign/independent - if you want that, then using your own Bitcoin Core full node is a must.
Spent some time investigating how to do that, so sharing here in case someone wants it. Feel free to point any ways to do it better.
How-To:
  1. Go to the usual Trezor wallet site, then open the wallet you want to import to Core (don't forget passphrase if needed). Copy the ypub text string.
  2. Convert the ypub to xpub using something like this: https://jlopp.github.io/xpub-converte You can save the page and run it offline/airgapped in something like Tails if you don't trust it. There is no security risk (not a private key) but only privacy risk (with your public keys the site can see all transactions/balances of that wallet)
  3. Put the xpub in a Core RPC importmulti command with this formatting:
    importmulti '[{"range": [0, 1000], "timestamp": "now", "keypool": true, "watchonly": true, "desc": "wpkh([000000f1/84h/0h/0h]your_xpub_goes_here/0/)#7x87wdy3", "internal": false}, {"range": [0, 1000], "timestamp": "now", "keypool": true, "watchonly": true, "desc": "wpkh([000000f1/84h/0h/0h]your_xpub_goes_here/1/)#0jzlnc5f", "internal": true}]'
Then open Bitcoin Core and do these other steps...
  1. In File>Create Wallet, create a wallet with "No Encryption" & "Watch Only" - call it anything you like (TrezorA for example).
  2. Open Window>Console, select the wallet you just created (on the pull-down menu at the top) and then paste the importmulti command where you put your xpub.
  3. Core will complain that the checksum is wrong (the "7x87wdy3" and "wdxy2s2t" parts in my example) replace them with the right ones shown in the message and retry.
  4. You should see the wallet imported with success, but with no transaction history. It is necessary to rescan the chain to index the transactions that wallet made. To save time, you can use the blockheight of the first block where you made a transaction with that trezor, for example: "rescanblockchain 590500".
You can find out the block by putting the hash of your first transfer in a block explorer like https://live.blockcypher.com/, look for "blockheight" If you have no idea which block has your first transaction, you can just rescan the whole chain by typing "rescanblockchain 0" in the console (but Core will take way longer to do it).
That's about it, all transactions made from what wallet should then appear in Core and it will warn every time funds are received or spent. You can be running your own full node and constantly monitoring your wallet, without having to use the Trezor or load Satoshilab's site.
You cannot spend from that wallet in Core, but you can use it to generate receive addresses and send to it (keep in mind that if you generate bech32 addresses in Core, those transfers will not appear at Trezor wallet since it doesn't support it yet :| )
Edit: Forgot change addresses, fixed importmulti example.

I started Bitcoin Mining with a guy. But all the funds I deposited are in the Watch Only Wallet imported into my wallet and my default wallet has 0 BTC

Hi, I started Bitcoin mining with a guy and he says that all the funds i deposited are in Watch Only addresses imported into my wallet. My wallet has 0 btc. I am doubting that the guy is scamming me. Is there any way I can get the private keys of those watch only addresses so that I can have my funds back into my default wallet ? Can anyone help me ?

Looking at the Bitcoin wallets the last year, the largest all increased their stacks exponentially. It is key to watch this as we are seeing the wealthy simply accumulate more BTC in this market while the retail, weak hands, are giving it up. Whales are only getting bigger.

Question: Is there a watch-only Bitcoin Cash wallet?

I suspect that if I frequent the local green grocer enough, I may be able to convince them to accept Bitcoin Cash. They are using a tablet as a POS terminal though. It would be bad if the POS terminal stored the day's payments.

Watch-only wallet in Bitcoin Core / Qt

In Electrum I can create a watch-only wallet, upload it into my server and accepts payments so that it's safe because there's no need in the private key and bitcoins can't be stolen if an attacker breaks into my server. Also I can see the balance on that wallet from Electrum application running on my desktop. How can I do that with bitcoin Core and Bitcoin-qt application?
