This post explains the process of sideloading the Zenon Ledger Embedded App from pre-compiled binaries on a Ledger Nano S/S+ device.

The Zenon community is currently in the process of registering the Zenon Ledger Embedded App for admittance to the Ledger Live application. Once approved the Zenon Ledger Embedded App will be available for installation in the Ledger Live application.

The Zenon Ledger Embedded App can be installed directly on a device. This process is called sideloading and should be used for testing purposes only. Sideloading is only possible with a Ledger Nano S/S+ device and requires you to trust a not genuine application.
