I tried to import my private key from the BTC Core Wallet into another wallet because it doesn't work anymore, it says that there is no fund, even if it is 100%, as I can see on the Explorer.

I really need help. My Btc Core wallet is not running, but I was able to open a new wallet with my Dat.dat file and check my private key, it's all correct.

  • is there something i missing ? Privatkey i got, but my Btc not... – Rob Apr 29 at 5:18

    Did you export with dumpprivkey? The wallet.dat can only be recognized by Core. – MCCCS Apr 29 at 7:52
  • yes i did, i get so confused why it's has no fund ? it seems like a wrong key, it says not spendable not match with public key, and if i import without the Public Adresse it says no fund on it. i try now to synchronised BTC Core aigain, but it will take so long. thatwhy i tryed to import the privatkey on two other wallet, but both doesn't work. On explorer the funds are still there, no transaction happen. – Rob Apr 29 at 9:09

    If it's says "not spendable" then it's very likely that you've been scammed and they made your Bitcoin Core see their money that you can't spend as your money. Maybe that's the case? You can't import it because you don't have the private key for the address. – MCCCS Apr 29 at 9:15
  • thats very odd, how ? my adresse still remain the Balance on blockchainexplorer, but the Privatkey seems 0 Balance. As far i know you can't change a private Key unless you change the Adresse. – Rob Apr 29 at 13:48

It sounds like the problem may be that the new wallet derived a different type of address from your private key.

Normal wallet function will present you with a new address each time you receive coins. Each of those addresses will have an associated private key, that needs to be used to spend the funds. Note that the same private key is not used to derive multiple addresses in a wallet, there is a 1:1 relationship for private keys and addresses.

So when you want to import that private key to a new wallet, you need to make sure the new wallet derives the correct address from it (ie, the same one your original wallet did, when you originally received the payment), otherwise the new wallet is showing a different address then it will not show your funds, since it is looking in the wrong place.

This question has a bit of info about different address types.

As a first step, compare the first characters of the address that holds the funds, and the address that the new wallet generated. If they are not the same (eg the original is 3... and the new wallet is bc1...), then you will need to either instruct the new wallet to generate the correct type of address, or if this is not possible, you will need to find a different wallet that is capable of doing so.

Note: if your bitcoin-core wallet is fully synced, you can run the command bitcoin-cli listunspent, to get a list of UTXOs that the wallet is keeping track of. You can look through the list to confirm the balance of specific addresses using this command, to ensure you are attempting to export the correct private key.

Redo the import. Start via file > new/restore, enter a unique filename and click next to begin the process. This time prepend one of the following to the private key: • p2wpkh: if the address in question begins with bc1 • p2wpkh-p2sh: if the address in question begins with 3 For example: p2wpkh-p2sh: KwZfCiAcXNz………………ntA6bXCQrG6JbxMy
