Multibit Classic and Multibit HD were widely used Bitcoin wallets before they were abandoned. Years later, people find an old laptop, backup drive, .wallet file, .key file, or mbhd.wallet.aes file and discover that the original software no longer syncs cleanly or the password is gone.
That does not always mean the Bitcoin is lost. Multibit recovery is often a file-format and migration problem, not a blockchain problem.
Situations we evaluate
Forgotten Multibit password. Encrypted Multibit wallet files can often be tested offline. Recovery depends on how much you remember about the password and whether the wallet file is intact.
Old wallet file, modern software won't open it. Multibit is obsolete. We can evaluate Classic and HD wallet files directly instead of relying on the old app to sync or broadcast.
Private-key export confusion. Some Multibit Classic wallets have .key exports, and some users can still export keys from the old app. If you are unsure whether an export contains the spendable keys, we can help inspect the format safely.
Multibit HD seed or derivation issue. A phrase that does not restore where you expect may still be valid under the wallet's original derivation path.
What to do right now
- Do not delete the old Multibit folder, even if the app looks broken.
- Copy the wallet files before trying more tools.
- Look for
.wallet,.key,mbhd.wallet.aes, and old backup folders. - Write down password fragments and the approximate year you used the wallet.
- Ask for a free evaluation before sending any secret material.
