2. install the PoSW application on your device via the Ledger Manager
Confirm the installation when required on your device.

For each sending transaction, the Ledger device will ask you to verify the details of your transaction (amount, fees, address) before confirming. Press right button on the Nano S, tap on the Blue.
PoSW works on the Bitcoin wallet as they are both tracked on the same blockchain.
HOW DOES IT WORK
This application is an account manager, where you can send and receive PoSW transactions and check your balance.
The only way to open it is to connect your Nano S or Blue, make your PIN code and launch the PoSW app on your device. Without the device, the app won't launch.
For each sending transaction, your application will ask you to verify it on your device: your device will display the amount, recipient address and gas rate you will have to manually sign by confirming everything is alright on the device.
The Ledger Wallet PoSW automatically updates.
