Is my wallet in rescan phase? No wat to check it via bitcoin-cli ?

Hello,
I'm trying to determine if my wallet on Bitcoin Core is rescanning for txs.
I would like to do a shell script to do this
Anyone has a way to do this via bitcoin-cli? It seems that there is no way but maybe there's something I'm missing.
Thanks in advice for help or suggestions.

Bitcoin Unlimited how to delete unconfirmed wallet transactions without rescan

So due to a mistake on my part while splitting my BCH and BTC, all my backups of my BCH wallet.dat file have unconfirmed transactions that are on the BTC blockchain. I downloaded the BCH blockchain using Bitcoin Unlimited in prune mode because storage is tight. I assumed that when it got past the BTC transactions it would simply delete them (they're the wrong transaction format and not in any block) but it hasn't.
All the methods of deleting transactions from wallets rely on using -zapwallettxes and -rescan, which I would rather not do (it took quite a while to download the blockchain to begin with).
Is there any way to delete those transactions from the wallet file without a rescan?
Note - the blockchain still has 10 days left to download, but the transactions are older than that.

So I just opened my bread wallet and had to make a new passcode and use my paper key to get the wallet. My wallet loaded at $0 which I know is not true. How do I get my balance back? I saw something about rescanning on another bitcoin post. How would I do that?

Could someone help me out? I downloaded Bitcoin ABC, synced with the blockchain, and rescanned my backed-up wallet. Why is my balance still zero?

After I rescanned with my wallet, I see all my transaction history, but beginning August 1st, they're grayed out (unconfirmed).
What's the best way for me to get my coins?

Have a wallet.dat from a mining pool back around 2010. Had coins on it but can't get it open. Can anyone help me out?

Back around 2010/2011 I mined some bitcoins using one of those mining pools. I've tried to figure out which I used, but can't. I kept the wallet.dat even after all these years but have long forgotten the password.
So do I have any hope of getting this thing opened up? Only thing I've tried in the last 5 years has been right now. I've downloaded bitcoin core, created a wallet, shut it down, swapped out the new wallet.dat with a copy of the wallet.dat with coins trapped away in it and when I opened the btc core program back up and went to console I typed in "-salvagewallet" which gave me a "Method not found (code -32601)" error.

thanks for any help.

Edit: My old wallet.dat file is only 104Kb in size. I notice the newer ones are over 1000Kb. Was that normal for 2010/2011?

How-to: setup your multisignature Cold wallet in Bitcoin Core 0.20 (highest security setup)

Last release of Core is amazing !
The main new feature is sortedmulti descriptor. This allows you to import your multisig setup in Core almost as if it was Electrum when combine to the new PSBT export in GUI !
As it needs command line and some weird checksum, you also need to input very long command in the console and if you made a mistake, you cannot copy the last command you made. So take your time when the commands are long to check everything and don't miss anything, use copy paste before validating the long command. You only have to do this once fortunately :)
I detail here how you do it with a k of n setup, good luck:
And you are DONE ! You should get the exact same addresses than Electrum and you can created receiving addresses in Qt ! To send money, just go to the send section, use the new coin control feature and export a partially signed transaction. You can use HWI or Electrum to sign it with your hardware wallets !
Notice: You can import more or less than 2000 addresses of each type. If less, blockchain rescan is faster but you may need to redo what we have done here later when all addresses will have been used once. If more, it is the contrary.

You now have the most possibly secure setup in one software: multisig with hardware on the full node wallet. When Bitcoin Core 0.21.0 will be out, we will also have native descriptor wallet so maybe we will have HD version of this. But for now, this is the best you can do ! Enjoy :)

P.S. : if you like doing things in one shot you can do the last two steps in one big command: importmulti '[{"desc": "wsh(sortedmulti(k,[path1]xpub1.../0/*,[path2]xpub2.../0/*,...,[pathn]xpubn/0/*))#check_sum0", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "keypool": true}, {"desc": "wsh(sortedmulti(k,[path1]xpub1.../1/*,[path2]xpub2.../1/*,...,[pathn]xpubn/1/*))#check_sum1", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "internal": true}]'

Coins possibly stuck in tumbler

I believe some of my coins may be stuck because the tumbler crashed before completing. I use the UI to access my wallet and run the tumber, however it says that I have very little coins while bitcoin core is showing much more in watch only.
I looked on reddit for any possible fixes and I was told to run this:
 python wallet-tool.py -m 15 my-wallet-file.json 
The commenter said that the coins are most likely stuck in a higher mixdepth so running this will increase the maximum mixdepth. Unfortunately this doesn't appear to do anything for me, or I'm just not smart enough to see what was done. I've included what happens when I run this command below
(jmvenv) [email protected]:~/joinmarket-clientservescripts$ python wallet-tool.py -m 15 wallet.json User data location: /home/caleb/.joinmarket/ Enter wallet decryption passphrase: Traceback (most recent call last): File "wallet-tool.py", line 9, in  jmprint(wallet_tool_main("wallets"), "success") File "/home/caleb/joinmarket-clientservejmclient/jmclient/wallet_utils.py", line 1242, in wallet_tool_main wallet_password_stdin=options.wallet_password_stdin, gap_limit=options.gaplimit) File "/home/caleb/joinmarket-clientservejmclient/jmclient/wallet_utils.py", line 1133, in open_test_wallet_maybe return open_wallet(path, mixdepth=max_mixdepth, **kwargs) File "/home/caleb/joinmarket-clientservejmclient/jmclient/wallet_utils.py", line 1179, in open_wallet wallet = wallet_cls(storage, **kwargs) File "/home/caleb/joinmarket-clientservejmclient/jmclient/wallet.py", line 1031, in __init__ super(ImportWalletMixin, self).__init__(storage, **kwargs) File "/home/caleb/joinmarket-clientservejmclient/jmclient/wallet.py", line 1282, in __init__ super(BIP32Wallet, self).__init__(storage, **kwargs) File "/home/caleb/joinmarket-clientservejmclient/jmclient/wallet.py", line 335, in __init__ .format(self.max_mixdepth)) Exception: Effective max mixdepth must be at most 4!

Another one (old wallet recovery)

Hey everyone,
I've been out of the crypto game for a long time, but managed to dig up a wallet that I had stored on an old PC from early 2015. It wouldn't have much in it, maybe a few BTC at most, but it would be nice to recover it and cash out. The machine had Bitcoin Core installed, hasn't been connected to the internet since 2015, and is currently interstate - I've copied wallet.dat and that's all I have access to for now. The wallet is encrypted, backed up, copied to multiple secure locations, etc, and I remember the passphrase, but from what I've read in other threads, the private keys are the important part and I may need to do a "key dump"?
I tried installing Electrum and importing the wallet, but Electrum doesn't recognise the file. Am I right in thinking that the following would be the best solution?
  1. Download and install Bitcoin Core.
  2. Place wallet.dat into the appropriate directory.
  3. Open Bitcoin Core and allow it to "catch up" and download 240 GB worth of blockchain history.
  4. Possibly be forced to input the passphrase to access the wallet again, and transfer BTC out to an exchange of my choosing (unsure if this is how it would work at this stage).
Is there a way to recover the wallet without being forced to download hundreds of GB worth of data? I live in Australia, with typical Australia-tier internet, and it could quite literally take up to a week to download.
Apologies if there's any shortfall of knowledge on my end of things, it's been a long time since I've kept up with crypto and things seem to have changed quite a bit over the last four years. I appreciate any advice, and y'all are welcome to shame me on my relative ignorance, lol. Thanks!

Help recovering coins from pruned wallet

I have about 200ish dollars worth of bitcoin waiting in a wallet and I recently tried to access them on bitcoin core and i was told it was pruned. I tried increasing the prune size to 50 gigs in the settings but I'm assuming that it wont download things from the past it will just store more info as time goes on. I was told to try to rescan or reindex bitcoin core so i put rescan in the config first and I got a parse error; same thing happens with reindex. I also tried using the command box in bitcoin core and it isn't detecting the commands.
Id appreciate if you guys have any advice. I wrote down the private keys long ago but I have moved twice since then and I feel that they're buried deep in some obscure area of my house that I wouldn't be able to find anytime soon.

All my BCH was stolen and I cant figure out why.

UPDATE!!! I RECOVERED MY BCH!!! YOU NEED TO RESCAN YOUR ADDRESSES IN THE WALLET-SPECIFIC SETTINGS IF YOU UPDATE THE BITCOIN.COM MOBILE WALLET.
Boy that was a great learning experience. THANK YOU GUYS SO MUCH FOR HELPING <333333
*WHAT ACTUALLY HAPPENED IN SUMMARY: I was sending my friend free bch as I want to help him make his own special coin as an intro to the crypto world, and by this point I didn't pay attention to my balance. Then I remember to update the wallet for the upgrade for slp tokens, and when I saw my wallet it had most transactions I remember making but not all, and the last recorded one was one that emptied my whole balance to a random address! So I was startled and couldn't figure out what could have happened since it seemed obviously fully synced! But with the help of an awesome community member I learned it could have not resynced properly... And watya know. It resynced properly. Hours later I was confirmed by the bitcoin.com wallet support too, to find the resync feature to most likely recover the funds. ✔️

I was sending a friend his first crypto (BCH) to make a SLP token for him and it was super sweet, and then I noticed all my money was gone. It had been all sent out at a random time a month ago that I certainly don't remember moving any BCH or crypto at all. Anything I can do? It was a great introduction to crypto to my friends who are getting inspired.

Because I dont know how i did anything wrong I'm seriously freaked out about how I'm possibly supposed to hold even 100$ worth of crypto on a mobile wallet.
details: bitcoin.com wallet, bitcoin redeemed from bitcoin.com golden ticket giveaway by swiping a paper wallet, never used the BCH seed phrase anywhere else but the app that made it.
edit* grammatical and THANK YOU for trying to help me figure this out, I hope I'm mistaken.

Armory

I have no clue whats going on right now. I downloaded armory, made a wallet, and sent coins to it. Then I noticed I was offline and upon further research realized I needed to download the blockchain database. So I downloaded bitcoincore and waited about 2 days for it to download everything on the bitcoin core app. While it was doing this armory was also running and the menus where it says "build database" and "scanning transaction history" was up. The only box that wast lit up green was "scanning transaction history" and I've had this apple loading pinwheel thing just spinning around the past 2 days as well. Last night Bitcore finished downloading everything so I closed armory and opened it back up but ever since last night it's just been on scanning transaction history. I went to bed hoping it'd be done this morning, still not. I waited until now, still not done. I've closed and opened it a few times, made it rebuild and rescan the database, and did a factory reset where it deleted the armory database, rebuilt then rescanned it. In all honesty, I have no clue what I was doing usually turning something off and back on is the magic fix to computers. I tried to just take the coins out using my backup paper wallet on blockcahin.info but they said my QR code was invalid. Advice?

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

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.

BUG: After Shuffling with Electron Cash, funds disappear on Bitcoin.com wallet

I've imported my Bitcoin.com mobile wallet seed to Electron Cash in order to shuffle my coins. Around 75% or my coins are shuffled now and everything works fine on EC.
