Transferring Funds from Bitcoin Core Without Full Sync

So I got Bitcoin Core installed and received 500 bucks from a buddy, but I totally didn’t realize I had to wait for the full blockchain to sync to access my funds. Any chance I can pull those funds out before that? It's a non-legacy wallet, so 'dumpprivkey' is a no-go for me.

Try putting your private key into blockchain.com, that could work.

Seriously, don’t share your wallet file with anyone claiming to help you. Totally not safe. According to Ava Chow, a Bitcoin Core developer, you might theoretically export private keys, but that ain’t available in the client yet. You may have to mess around in the code, but I wouldn’t recommend it unless you know what you're doing. Why not just let it sync?

Or consider making raw transactions with 'createrawtransaction' and sign it with 'signrawtransaction'. You could also import your wallet.dat file into a different wallet if you’re careful.

What other wallets accept.dat files? I’ll give it a shot.

Also, can't do raw transactions until it's synced... I have no clue what to do anymore.

If you don’t understand commands like 'createrawtransaction', don’t touch them. Just let your node sync; that’s the safest route.

Can’t do that, it keeps failing and throwing errors. I’ve tried uninstalling, but I can’t lose these funds.

What errors exactly? Mind sharing the debug log?

Here's what I got: 2024-12-29T22:35:11Z Synchronizing blockheaders, height: 33559 (~4.09%) 2024-12-29T22:35:12Z Shutdown in progress... And some other junk.

You haven’t even synced block headers? Try running bitcoind with -resync. Also, mind sharing your config file (with sensitive info hidden)?

Tried that. The error popped up after I reinstalled it. I was 40% synced before.

You can always switch to Electrum or set up a pruned node to speed things up. Just backup your wallet.dat file first! You should be fine if you know which address got the funds.

How do I use that method? Got no idea what I’m doing here.

If you don’t understand raw transactions, then it’s risky. I’d just recommend downloading a pruned node and restore from your wallet.dat.

How do I download a pruned node? It keeps crashing on me.

You only need the transaction from December 28th? That’s the big one?

Yeah, bc1 address from Bitcoin Core. It needs to sync, but errors keep happening.

Have you tried this method: 1. Start Electrum, create a new wallet. 2. Choose 'Standard Wallet'. 3. Select 'I already have a seed' and enter your mnemonic.

I’m not talking about a seed. This is a non-legacy wallet, no mnemonics for me. The error says: 2024-12-30T00:50:44Z failed, bad-txnmrklroot, hashMerkleRoot mismatch.
