Wallet.dat recovery
Bitcoin Core password (wallet.dat)
We recover access when your wallet.dat password no longer works after reinstall, migration, keyboard changes, or old backup restore. Besides controlled brute-force, we use custom mutation heuristics and large internal pattern dictionaries built from real recovery practice to prioritize likely candidates before heavy full-space search.
Why a remembered password may fail
- Keyboard layout mismatch (EN/RU, different physical layouts, accidental layout switch during password creation).
- Caps Lock / Num Lock state differences and shifted symbols (`!`, `@`, `_`, `-`, etc.).
- Wrong key presses while typing fast, including neighboring-key substitutions and duplicated characters.
- Autocorrect / input-manager effects (especially when fragments were saved from mobile notes).
- Hidden whitespace or invisible characters copied from notes, messengers, or password managers.
- Version/environment drift: password was created in one setup and tested later in another OS/app context.
How we search (not only brute force)
We combine structured brute-force with weighted candidate generation: layout transforms, typo graphs, symbol-shift variants, known pattern rules, and ranked dictionaries. This usually outperforms naive exhaustive search in practical wallet.dat cases. Final work runs offline in isolated infrastructure after scope agreement.
What to prepare for initial assessment
- Approximate Bitcoin Core version and confirmation you have a backup
wallet.dat. - Password memory hints: estimated length, remembered fragments, likely words, keyboard layout, years/number patterns.
- Context: when access last worked, what changed (OS reinstall, keyboard, migration), and what has already been tried.
Ethics and intake policy: we do not accept wallet files sold on the internet or “found” archives with unclear ownership. Before work, we screen wallet indicators (hash/address fingerprints) against known fake/scam datasets and reject suspicious submissions.
Describe your wallet.dat case
We usually reply within one business day. Send only masked description first — no full password in plain text.
How the process works
- Initial feasibility review and risk screening (including fake-wallet checks).
- Agreement on scope, confidentiality, pricing, and secure transfer channel for sensitive material.
- Offline password recovery workflow with staged verification and documented handoff protocol.
Trust and fraud safeguards
We prioritize legitimate owner cases, reject suspicious internet-sold wallets, and keep technical processing isolated from public channels.
