Daedalus 1.0.0 is the first release of Daedalus to incorporate Byron reboot improvements, including a completely re-engineered Cardano node and Cardano wallet, the core backend components of Daedalus.
Because of these fundamental changes, Daedalus 1.0.0 requires a completely separate installation and does not share any data with earlier versions of Daedalus.
Daedalus 1.0.0 Installation
1. Download a Daedalus installer
Go to the Daedalus website at https://daedaluswallet.io/ and download the appropriate Daedalus installer for your operating system.
2. Close any running version of Daedalus
If you have any Daedalus instances running, close them before installing Daedalus 1.0.0.
3. Install Daedalus
Launch the downloaded installer and follow the installation steps.
4. Launch Daedalus Mainnet
After completing the installation you will have the new Daedalus Mainnet application installed. You can recognize it by the new icon and the new application name, which is now Daedalus Mainnet instead of Daedalus. Double click the Daedalus Mainnet icon to launch it.
5. Initial setup
Since this is a completely new Daedalus installation, you will need to go through the initial setup.
Follow the on-screen prompts and select your preferred language, number format, date format, and time format preferences, then click Continue.
In the following step, you will need to read and accept the terms of service agreement.
6. Import wallets
Note: This step is only required if you have existing wallets you want to import into Daedalus 1.0.0. If you are new to Daedalus, or do not want to import old wallets, you can skip this step.
The wallet import feature will run automatically when Daedalus 1.0.0 is first launched and an older version of Daedalus (with wallets) is installed on the same computer.
Daedalus will automatically detect any wallets from your previous Daedalus installation.
Select the wallets you want to import and click on the Import selected wallets button.
Selected wallets will be imported. Click on the Close window button to leave the wallet import screen.
You can always import wallets later by clicking Add wallet and then selecting Import.
If you have issues importing wallets, follow the Learn more link to this support article, which explains how to import wallets from Daedalus backups, even if they are incomplete.
7. Blockchain and wallet synchronization
After importing wallets, or otherwise, the main Daedalus user interface will be displayed, with blockchain synchronization happening automatically in the background. You can monitor blockchain synchronization progress by hovering over the spinning icon in the top-right part of the user interface.
If you have imported wallets, then their balance and transaction history will be synchronized with the blockchain as it is downloaded. Do not be concerned if your imported wallets show incomplete or incorrect information prior to full blockchain synchronization.
The synchronization process in Daedalus 1.0.0 is much faster than in earlier versions of Daedalus. However, since this is a completely new copy of Daedalus the entire Cardano blockchain must be downloaded, which may take some time (depending on network conditions).
Once this initial synchronization is completed, Daedalus will only need to download the new blocks which have been created since the last time you opened Daedalus, and subsequent synchronizations will be significantly faster.
8. Previous versions of Daedalus
Once you are finished importing wallets into Daedalus 1.0.0, you can run both Daedalus 1.0.0 and your previous version of Daedalus at the same. It is recommended that you compare balances and check that all desired wallets have been imported correctly.
If all of your wallets and their balances are correct in Daedalus 1.0.0, you no longer need to use your previous version of Daedalus. Instructions about how to uninstall old Daedalus versions and their state directories will be provided soon via the Daedalus newsfeed.
