Forgot your Bitcoin Core wallet.dat password?
If you still have the wallet.dat file, the coins are inside it — encrypted, not gone. We recover the password that unlocks the master key.
How Bitcoin Core wallet.dat recovery works
Bitcoin Core never stores your password. It stores an encrypted master key inside the wallet.dat; your password derives the key that decrypts it. We attack that password — the keys themselves are never brute-forced — and confirm success the moment an encrypted key decrypts cleanly.
Isolate the hash
We pull the encrypted master-key hash from the wallet.dat with bitcoin2john. No plaintext keys are ever exposed, and you can run the extraction yourself if you would rather not share the file.
Hint-driven search
From what you remember — length, fragments, character habits, the era the wallet was made — we build hashcat masks and rules for mode 11300, not blind brute force. Structure is what makes it tractable.
Merged-key forensics
When only some keys decrypt, the wallet often holds more than one key set or a second passphrase. We map which master key covers which keys — a frequent and solvable Bitcoin Core anomaly.
From first message to recovered funds
Tell us what you have
Your situation, the wallet.dat (or an extracted hash), roughly when it was created, and anything you remember of the password. No payment to assess.
Free assessment within 24 hours
We tell you honestly whether it is recoverable and what the search space looks like. If it is hopeless, we say so.
Sign the agreement
A service contract under Swiss law protects both sides before any data changes hands. We never ask for upfront payment.
We run the recovery
Cracking runs on dedicated offline GPU hardware. On a hit you regain full access to your wallet.dat and pay only the success fee.
Avoiding impersonators
We only use keychainx@protonmail.com and Telegram @keychainx. We never DM first on Facebook, Instagram, X or WhatsApp, never guarantee 100% success, and never ask for upfront payment or an “unlock fee”. Anyone doing so is impersonating us.
Bitcoin Core recovery questions
Do you need my actual wallet.dat file?
We work from the encrypted hash inside your wallet.dat, which we can extract with bitcoin2john without ever needing your keys in the clear. The wallet.dat holds no plaintext private keys, only encrypted material. We sign a service agreement first and can guide you through extracting the hash yourself if you prefer not to send the file.
I only remember part of my Bitcoin Core password. Can that still work?
Yes, and it is the best case. Partial recall, length, character habits and known fragments let us build targeted masks and rules rather than blind brute force, which is what makes an otherwise huge search space tractable.
Some of my keys decrypt but others do not. What does that mean?
That merged-key pattern usually means the wallet.dat contains keys from more than one source, or was encrypted under a second passphrase at a later date. We diagnose which master key protects which encrypted key set and treat them separately, which is a case type we handle regularly.
How much does Bitcoin Core recovery cost?
The fee is success-based: you pay a percentage of the recovered value only if we succeed. If we cannot recover access, there is no charge, and we never ask for upfront payment.
Locked out of your wallet.dat?
Send us what you remember. You get an honest assessment within 24 hours, and you pay nothing unless we recover access.
