A simple command line tool that exports the private Keys from a Multibit wallet file. The reason this tool exists is because Multibit is out of date and has known bugs. Exporting the private keys or wallet words from Multibit and importing them into another wallet may be the only effective way to access your funds.

Installation

  1. Install node version 6 or higher. You can get it from https://nodejs.org/en/download/.
  2. Open a command prompt and install this utility: npm install -g mbexport

Now you are ready to export the private keys from your wallet.

Locating your wallet file

Mac OS

Version Wallet file location
Multibit Classic ~/Library/Application Support/MultiBit/*.wallet
MultibitHD ~/Library/Application Support/MultiBitHD/<wallet-id>/mbhd.wallet.aes

Windows

Version Wallet file location
Multibit Classic C:\Users\<username>\AppData\Roaming\MultiBit\<wallet-name>.wallet
MultibitHD C:\Users\<username>\AppData\Roaming\MultiBitHD\<wallet-id>\mbhd.wallet.aes

<wallet-id> is a very long, random directory name that acts as a globally unique identifier for a wallet. It is starts with mbhd- followed by a long string of letters, numbers and dashes. You will have one directory like this for each wallet.

<wallet-name> is the name that you gave the wallet when you created it. You will have a ``.wallet file for each wallet.

<username> is your windows user name.

Once you figure out the name and location of your wallet file, you can export the keys.

Exporting Your Keys

Open a command prompt and type the following command:

mbexport <path-to-wallet-file>

For example, if you are using Multibit HD on MacOS, you would type something like:

mbexport ~/Library/Application\ Support/MultiBitHD/mbhd-aff7bb4a-8a5d9101-e7e97974-f999c7fb-53795c76/mbhd.wallet.aes

TIP: If you can find the wallet file in the file explorer application, you can type mbexport in the command prompt, then drag the file from explorer to the command prompt. It should fill in the long file name for you.

When you run mbexport, it will ask you to enter the passphrase for your wallet. Once you do will list any private keys and mnemonic seeds that it finds in the file. If you run mbexport on a Multibit Classic file, the output will look simliar to this:

multibit classic wallet opened
Enter your passphrase: ***

For Multibit HD, it will look like:

MultibitHD wallet opened
Enter your passphrase: ***
