We are excited to announce that the Mina App 1.0.6 is now available in developer mode on Ledger Nano X and Nano S. With the support of community contributors, Ledger, and O(1) Labs, all Mina community members will now be able to use the application at their own risk while the wallet completes its audits.
How to Download Mina on Ledger
In order to view the unaudited Mina app, the Developer Mode must be activated. Here is how to do that:

- Click the gear button on the top right corner.
- Select “Experimental features”.
- Toggle the “Developer mode” functionality on.
Because Ledger Live only releases new apps and updates on the latest versions of the firmware, users should update their Ledger nano firmware, 2.1.0 on Nano S and 2.0.2 for Nano X devices.
After activating developer mode, users can download the unaudited Mina app. Here is how to find the Mina app in the app catalog.

- Select the “Manager” menu on the left panel.
- Make sure your firmware is up-to-date (at least 2.1.0 for Nano S or 2.0.2 for Nano X.)
- Select the “App catalog” tab.
- Search for Mina.
- Click install.
Currently, signing takes at least 1.5 minutes, and delegating takes about 3 minutes. Users of community-made browser-extension wallet, Auro, are encouraged to not click away from the browser extension before signing is complete. This helps ensure the transaction sends successfully.
What’s Next
The Mina Foundation is currently working with community wallet creators, Auro and Clor.io, to update their applications to inform users about the wait signing and delegating times.
Although the Mina Ledger application has already been audited by Least Authority, the application still needs to be audited by the Ledger team. While that is being completed, users should use the application at their own discretion. Once the Mina app is audited and approved, Ledger support for Mina can go public, at which point users will be able to use Ledger to custody MINA tokens without activating the Developer mode.
