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.
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.

About Mina Protocol
Mina Protocol is being incubated by O(1) Labs, the leader in zk-SNARKs and verifiable computation. Mina Protocol, the world’s lightest blockchain, provides a foundation for the decentralized digital economy (Web 3.0), by affording all participants fully P2P, permissionless access to the chain, from any device. By utilizing recursive zk-SNARKs, the Mina blockchain always stays the same size — about 20 kilobytes (the size of a few tweets). Recursive zk-SNARKs allow nodes to rapidly share and update proof of the correct blockchain state across the network. This breakthrough application of zk-SNARKs solves the issues of scalability and high barrier to entry for nodes that have plagued legacy blockchains to-date. By making it easier for nodes to participate, Mina improves decentralization and therefore security of the network. The Mina blockchain can be easily accessed from any device, including phones and browsers, and can be seamlessly integrated into new decentralized applications (dapps).
