GreenAddress was one of the Bitcoin wallets that prioritized multisignature security and SegWit adoption. While the application has since transitioned into Blockstream Green, some users with long-dormant wallets may still need the original software to regain access to their funds.
If you are looking for these legacy versions, you can still find them archived on GitHub. Depending on the platform you originally used, you will need to look into specific repositories to find the correct binary.
Where to find the downloads
The developers have maintained several repositories for different platforms.
Windows, Mac, and Linux
For desktop users, binaries can be found in the WalletElectron repository. Versions 0.1.01 through 0.1.04 are currently available for download.
Android
Android users can find binaries in the WalletCordova repository. You will find versions 0.0.74 through 0.0.88 ready for use. If you require a version older than 0.0.74, you will have to compile it yourself from source code.
Chromium extensions
If you used the browser-based version, head to the WalletCrx repository. This archive contains versions 0.0.71 through 0.1.04.
