MultiBit Classic depends on a special fork of Bitcoinj for its Bitcoin support.

XChange for access to several Bitcoin exchanges.

Bitcoinj Enforcer Rules to prevent dependency chain attacks.

Install4j for creating installers for Windows, Mac, Linux.

Bitcoinj for access to the Bitcoin network.

With Maven then download it first and follow their installation instructions.

Maven as the build system, so the usual Maven processes apply.

MultiBit Classic relies on the following technologies: We refer to MultiBit Classic and MultiBit HD to keep them separate. MultiBit is now in maintenance mode as it has largely been replaced by MultiBit HD. MultiBit is a Simplified Payment Verification (SPV) Bitcoin desktop client. Multibit was a fantastic piece of software in its time, and we want to thank the Multibit developers for such an important contribution to Bitcoin’s history. The version shown in the Multibit HD video is the soon-to-be-released next version. Please note that the version of Electrum available for download today (version 2.8.3) doesn’t fully support the importing Multibit HD wallet words.

Videos that demonstrate how to move your wallet to Electrum are available on YouTube. We recommend that all Multibit users discontinue using it and you move your keys to other wallet software of your choosing. Thus, KeepKey will discontinue support and maintenance of Multibit, effective immediately. By focusing our attention on the KeepKey device, we will continue building and improving the best hardware wallet available.

Unfortunately, KeepKey simply does not have the resources to support the current issues, nor to rebuild Multibit to ensure ideal user experience. The addition of SegWit in the coming weeks will mean the Multibit software has fallen still further behind.

Additionally, Bitcoin has gone through a fundamental change in regards to the way fees work. It has stubborn bugs that have caused us and Multibit users much grief. The reality is that Multibit is in need of a lot of work. We felt that it was important for Multibit to continue and hoped that with our existing support and development teams, we would be able to keep Multibit alive. Multibit played an important role in the Bitcoin infrastructure. At the time, the engineers who originally built and supported Multibit had announced that they would no longer be working on it or providing support. KeepKey acquired Multibit a little over 1 year ago.
