how do you transfer your Bitcoin core wallet while syncing?

Question

I would like to transfer my btc wallet to an electrum wallet. Syncing is taking to long.

Answer 1

Follow this guide.

Summary:

• Download Electrum and verify the signature to prove it was not modified in transit. Create a new Standard Wallet and choose "Create a new seed". Electrum will give you a seed phrase which you should write down on paper.

• If using Bitcoin-Qt, click Window -> Console.

• If your wallet is encrypted, use this command to decrypt it for 5 minutes (300 seconds):

walletpassphrase your-wallet-passphrase 300

If addresses with balance are known:

• Use the dumpprivkey command to get the private key. Repeat for as many bitcoin addresses as have money in them.

dumpprivkey <your bitcoin address>

If addresses with balance are not known:

• Use the dumpwallet command to get all private keys from the wallet.

dumpwallet path/to/exported-wallet.txt

• In the Electrum window, click Wallet -> Private Keys -> Sweep. Paste the private keys from Bitcoin-Qt here. Check the resulting transaction is okay and click Broadcast to sweep from the addresses in Bitcoin Core to the Electrum wallet.

  • If the address generated from the private key is wrong, then on the Sweep Private keys dialog box in Electrum click the Info box in the upper-right. It will give instructions for prefixing your private key so that the correct address is generated. For example if your address starts with 3 then use p2wpkh-p2sh:[your-private-key].

Warning: Make sure the Electrum wallet is not a watch-only wallet. The Electrum window title bar should not say [watching-only].

Turn off the syncing using the icons in the bottom right and send your coins using the send tab.
