Control Center is in the Start9 Community Registry. Install it from the StartOS Marketplace. It needs StartOS 0.4.0.2 or later.

Before you start

Install and fully sync these StartOS services. StartOS lists Electrs and Mempool as required.
If Electrs is stopped or still syncing, Control Center may not start. Wait for Electrs to finish first.

Install

1

Open the Community Registry

In StartOS, open Marketplace. Switch the registry to the Start9 Community Registry.
2

Install

Find Bitcoin Control Center. Select Install.
3

Set your PIN

StartOS shows a task: Set a PIN before using Bitcoin Control Center. Run Set PIN. Enter 6 digits twice. Save it in your password manager.
4

Open it

Start the service. Open Web Interface.
5

Sign in

Enter your PIN.
The PIN works only over https:// or the .onion address. Over plain http://, you see Insecure connection not allowed.

Options

In StartOS, open Control Center → Actions → Configure. Saving restarts the service.
  • Mempool URL Override: leave blank to use your Mempool service. Enter a URL to use another Mempool instance.
  • Log Level: keep Info unless support asks for Debug.
StartOS has no Electrum or Tor settings in the app. It always uses your Electrs.

Forgot your PIN?

Run Set PIN again. Your accounts and history stay. Everyone is signed out. See PIN and lock.

Back up

Use the normal StartOS backup. It saves everything. See Backup and restore.

Advanced: sideload the package

Only sideload if support asks you to. The website does not offer the .s9pk. Its Start9 Download button opens the Community Registry. Email support@hoseki.app and support will send you the file. Then sideload it in StartOS. Already sideloaded an earlier version? Back up before you switch to the registry version.
