Multibit Classic

Multibit Classic is a discontinued lightweight (SPV) Bitcoin wallet, first released in 2011 and shut down in July 2017. Because it is no longer maintained and cannot reliably sync with the Bitcoin network, it should not be used to store coins today. If you still hold Bitcoin in an old Multibit Classic wallet, your funds are not lost — you can export the private keys from your .wallet or .key file and move them to a modern wallet.

This page explains what Multibit Classic was, how it differs from Multibit HD, and how to recover your keys. If your wallet is password-protected and the password is lost, professional password recovery is available through KeychainX.

The history of Multibit Classic Bitcoin wallet

In the early days of Bitcoin, when the cryptocurrency was still finding its footing, there was a need for user-friendly and secure wallet solutions to store and manage the digital currency. Launched in 2011, MultiBit Classic emerged as one of the first successful software wallets, earning a special place in the history of Bitcoin.

The inception of MultiBit Classic took place amid the growing excitement around cryptocurrencies. Developed by Jim Burton and Gary Rowe, this lightweight Bitcoin wallet offered users an easy-to-use interface and speedy transaction processing. Built using Java, the wallet was compatible with Windows, macOS, and Linux, making it accessible to a diverse range of users.

One of the major advantages of MultiBit Classic was its Simplified Payment Verification (SPV) feature. This allowed users to interact with the Bitcoin network without having to download the entire blockchain, which was a significant benefit when compared to other wallet solutions available at the time. Consequently, MultiBit Classic was widely adopted by both novice and experienced Bitcoin enthusiasts.

Over time, the team introduced new features and improvements to enhance the user experience, such as adding hardware wallet support and enhanced security measures. The wallet’s reputation grew, and by 2013, it was responsible for managing around 1.5 million Bitcoin addresses, making it one of the most popular wallets of its time.

Classic moves to Multibit HD

However, the rapid evolution of the cryptocurrency landscape, along with the increasing sophistication of user demands, eventually caught up. In 2016, KeepKey, a hardware wallet manufacturer, acquired the MultiBit project and shifted focus to the development of MultiBit HD, a Hierarchical Deterministic (HD) wallet that aimed to address the limitations of its predecessor.

Despite the launch of MultiBit HD, the wallet began to face fierce competition from other software and hardware wallets that offered more advanced features and better user experiences. As a result, MultiBit Classic started to lose its edge in the market.

KeepKey shuts down Multibit forever

Finally, in July 2017, KeepKey announced the discontinuation of support and maintenance for both MultiBit Classic and MultiBit HD. This marked the end of an era for a once-pioneering Bitcoin wallet that had played a crucial role in the early adoption of cryptocurrencies.

Today, MultiBit Classic remains a testament to the rapid innovation that characterizes the world of cryptocurrencies. Its story serves as a reminder of how the landscape has evolved, and the importance of continually adapting to the ever-changing demands of the market.

Multibit Classic vs Multibit HD — what is the difference?

People often mix up the two Multibit products, but they store keys in completely different ways, so the recovery path is different too.

Multibit Classic (2011–2017) stores a bag of individual private keys inside a .wallet file, with an optional exported .key file. There is no seed phrase. You recover it by exporting or decrypting those keys.
Multibit HD (2014–2017) is a hierarchical-deterministic wallet. It is backed by a 12 or 18 word seed and stores data in an mbhd.wallet.aes file inside a wallet folder. You recover it from the seed words, or by decrypting the wallet with its password.

If you have a seed phrase, you have Multibit HD. If you have .wallet / .key files and no seed words, you have Multibit Classic. Our tutorials page covers the Classic recovery steps in detail.

Frequently asked questions about Multibit Classic

Is Multibit Classic safe to use in 2026?

No. Multibit Classic was discontinued in July 2017 and is no longer maintained. It struggles to sync with the Bitcoin network and should only be opened long enough to export your private keys, which you then move to a modern wallet such as Electrum or Bitcoin Core.

Where does Multibit Classic store its wallet files?

In an operating-system-specific Multibit folder. The files that matter are the .wallet file and any exported .key file. Exact Windows, Mac and Linux paths are listed on our tutorials page.

Can I recover a Multibit wallet without the password?

If you have an unencrypted .key export or the Multibit HD seed words, you can recover without the original password. If the .wallet or .key file is encrypted and the password is lost, professional password recovery may be required — that is what KeychainX does.

Is Multibit the same as Multibit HD?

No. Multibit Classic uses .wallet and .key files and has no seed phrase. Multibit HD uses a 12 or 18 word seed and an mbhd.wallet.aes file. See the comparison above for how each is recovered.

I lost my Multibit password — can the coins still be recovered?

Often, yes. Success depends on how much you remember about the password and how it was encrypted. The more hints you can provide (length, character sets, languages, likely words), the higher the chance. There is no guarantee, but many “lost forever” Multibit wallets are recoverable.
