Getting Started with Nostr

On Coinos, on top right corner menu icon, go to Settings and in there choose the middle tab that says Settings again.
Under integrations press Nostr and then find the secret key (in the form of nsecxxxx), note it somewhere safe (ideally a password manager).
Now you can go on a Nostr app and login with your nsecxxxx key. I suggest Amethyst on Android and Damus on iOS, or for a simpler interface on Android, iOS and the web try Primal.
Go with Primal for now for ease of use, so download the app and login with the nsec you saved earlier.
When you login, go to the menu on the left and choose your profile to start customizing it.
Upload a picture, choose a username and enter your new Coinos Lightning Address (username@coinos.io) in the Bitcoin Lightning Address field and Verified Nostr Address (NIP-05) field.
Go back to Coinos. from your dashboard click the Gear settings icon in the middle of the screen (next to your balance), and press to reveal the connection string. Choose the QR code.
Now back on Primal app go to settings and under wallet, disable the Primal wallet and choose to enter a custom wallet. There press to scan a QR code and scan the code from Coinos. Alternatively if you are doing it on the same device then copy the link from Coinos and paste it in the custom settings in Primal.
