Bitcoin Core Wallet Recovery Service
Locked out of your Bitcoin Core wallet? A single wallet.dat file, protected only by a password, with no seed phrase to fall back on: we’ve been recovering these since 2019, including wallets dating back to 2011.
What most people ask first
Does Bitcoin Core even have a seed phrase I can use?
No. Unlike wallets such as MetaMask or Electrum, Bitcoin Core never generates a 12- or 24-word phrase. Your keys live exclusively inside the wallet.dat file.
My wallet.dat loads but shows a zero balance. Are the coins gone?
Usually not. Bitcoin Core only shows a balance after it finishes scanning the blockchain, so a freshly loaded file can read zero until that rescan completes.
Do I need to download the entire blockchain to get my coins back?
No. Your private keys are what matter, not a full node sync. Syncing only becomes relevant afterward, if you choose to keep running Bitcoin Core as a node.
I found an old wallet.dat and have no idea what’s in it. Can you check?
Yes. We can check whether a wallet.dat holds funded addresses before any recovery work starts, so you know if it’s worth pursuing.
Our Bitcoin Core Recovery Services
Forgotten Your Password?
Bitcoin Core uses AES-256-CBC encryption with key stretching, so the only way back in is finding the password itself. We run systematic password testing on dedicated offline hardware, built around whatever you still remember: a base word, a pattern, the kind of password you used at the time. See our guide on recovering a forgotten Bitcoin Core password.
Corrupted wallet.dat File?
Bitcoin Core refuses to load the file, reports database errors, or crashes on startup. A corrupted wallet.dat doesn’t necessarily mean lost private keys: corruption often hits the database index rather than the key material itself. We extract the keys directly from the raw file data, bypassing the damaged database layer entirely.
Deleted or Lost wallet.dat File?
The file was removed, the OS reinstalled, or the drive formatted. On spinning drives especially, wallet.dat data can survive for years in unallocated space if the drive hasn’t seen heavy use since. We work from a forensic copy to carve out what’s left, so stop using that drive immediately. See our article on Bitcoin Core wallet.dat recovery.
Old Wallet From the Early Bitcoin Years
A wallet.dat from 2009 to 2014, made on a machine that no longer exists, isn’t a lost cause: age alone doesn’t rule out recovery. Older wallets are often easier, since the encryption’s key stretching is calibrated to the hardware speed at the time, and we work with both legacy Berkeley DB and the newer descriptor format.
Found a wallet.dat and Do Not Know What Is Inside
We can usually tell whether an old wallet.dat holds funded addresses before any recovery work begins, simply by checking its public keys against the blockchain.
Common mistakes to avoid
- Don’t keep running “Salvage Wallet” attempts on your original corrupted wallet.dat; work from a copy, since each attempt can make the file harder to recover from.
- Don’t buy a wallet.dat file offered for sale “with Bitcoin inside.” This is a known scam: either the seller keeps a copy of the keys, or the balance was never real.
- Don’t keep using a drive after deleting wallet.dat from it. Every new file written reduces the odds of recovering the old data.
- Don’t send your wallet.dat file to anyone offering an assessment before a signed agreement is in place.
Information that may be needed for recovery
- Whether you still have the wallet.dat file itself, or only the drive it was stored on.
- What you remember about the password: length, character types, any recurring pattern.
- Roughly when the wallet was created (Bitcoin Core wallets from 2009-2014 behave differently in a password search than newer ones).
- What happened, and what you’ve already tried.
You always stay in control of your funds. You move them yourself and we never take custody of your assets.
What we don’t do
Crypto Recovers does not offer scam recovery, stolen-fund recovery, or cryptocurrency tracing. If someone is selling a wallet.dat “with Bitcoin inside,” we will not take the case, and we advise you not to buy it: wallet.dat files offered for sale are a known scam. We only work with legitimate owners who can demonstrate ownership of the wallet.
Why Crypto Recovers?
Since 2019 we’ve handled more than 200 wallet cases, and Bitcoin Core makes up a disproportionate share of them: the wallet.dat format hasn’t changed much since 2009, and neither has the cost of forgetting an early password.
One client came to us in a panic after losing access to a local Bitcoin Core wallet holding just over 1 BTC; working from a list of password hints, we had it open again within days, and over $100,000 moved to a new wallet under their own control.
How Bitcoin Core Recovery Works
- Initial Contact
You describe the problem: forgotten password, corrupted file, or a deleted wallet. - Free Assessment
We estimate the search space or check the drive’s condition, and give you a realistic picture of success rate, timeframe, and cost. - Agreement and Verification
Identity and ownership checks, then a signed agreement. For password cases, we can work from an encryption-header extract with no private keys, so your wallet.dat never has to leave your possession during the search. - Recovery Work
Password testing runs on dedicated offline GPU hardware; file recovery happens in a secure, isolated setup. Depending on complexity, this takes days to several weeks. - Handover and Payment
You verify the wallet and transfer the coins yourself. The fee (20% of recovered value, No Cure No Pay) is settled in that same session. Full details: pricing page.
Bitcoin Core Wallet Recovery FAQs
How do I know you won't empty my wallet.dat once you find the password?
Because the setup never puts us in a position to. For password cases, we work from an encryption-header extract of your wallet.dat: it contains no private keys, so the search runs without your full wallet ever leaving your possession. At the handover, every transfer happens by your hand with both of us watching.
My wallet.dat loads but shows a zero balance. Are the coins gone?
Usually not. Bitcoin Core shows a balance only after it has scanned the blockchain, so a wallet.dat loaded on a fresh install reads zero until the rescan finishes. Look up your receiving addresses on a block explorer first. If the coins show there, the problem is syncing, not loss.
What if I only remember part of my password?
That is often enough. Partial memory shrinks the search space enormously: a known base word, the keyboard pattern you always used, or the rough length and character types. We build a structured candidate list around what you remember and test it systematically.
Do I need to download the whole blockchain?
No. Recovering access to your funds does not require a full node sync. The private keys inside wallet.dat are what matter. Syncing only becomes relevant if you want to continue running Bitcoin Core as a full node afterward, which is your choice.
Bitcoin Core says my wallet.dat is corrupted. Is it hopeless?
Usually not. A damaged database structure and lost private keys are two different problems, and the first does not imply the second. Make copies of the file, stop retrying salvage on the original, and contact us with the details.
I deleted my wallet.dat years ago. Is there any chance?
It depends on the drive. If it has been in daily use since the deletion, the odds shrink with every write. If it has been sitting in a drawer, deleted wallet data frequently survives. Old spinning drives sometimes fail on the second or third power-on, so leave the original untouched and send us the details before attempting anything yourself.
Does Bitcoin Core have a seed phrase I can use to restore?
No. Bitcoin Core does not use a seed phrase. Unlike wallets such as MetaMask or Electrum, Bitcoin Core never shows you 12 or 24 words during setup. Your private keys live exclusively in the wallet.dat file. For a full explanation of why Bitcoin Core works this way and what it means for recovery, see our article on Bitcoin Core and seed phrases.
