Connect Your Bleskomat ATM to GetAlby via Bleskomat Platform

GetAlby is a free and open-source browser extension which provides a custodial Bitcoin Lightning wallet in your browser. The developers of the GetAlby extension run an instance of a server software named LndHub.go to provide separate custodial Lightning accounts to each of their users.

LndHub.go is a free and open-source project which acts as a wrapper for the Lightning Network Daemon (LND). It allows a group of users to run different accounts with only one node in a trust-minimized setup. Ideal for hosted shared services or groups, families and friends that want to share their own node. For more information please visit the LndHub.go project page.

GetAlby Account Connection Credentials

It is possible to access your GetAlby account connection credentials via either the browser extension or from the website dashboard.

GetAlby browser extension

Click the extension icon to open it. Then click the “Manage accounts” link.

On the accounts page, click the three dots on the right side of an account. Then click “Export”.

Copy the text shown in the box labeled LNDHub Credentials URI – e.g. “lndhub://…@”

You will need these connection credentials later.

GetAlby website dashboard

Please note that the website dashboard only gives you access to the connection credentials of your GetAlby wallet account – it is not a wallet so you will need to install the GetAlby extension or a compatible mobile wallet app (Zeus or BlueWallet) and import your connection credentials there.

Navigate to the GetAlby website then click the “Dashboard” link in the top-right of the page.

If you already have a GetAlby account, use the login form. Otherwise, click the “Sign up with email” link near the bottom of the form.

Once you’re logged-in to your account, click the “Wallet” link at the top-center of the page. You should see a screen like the one in the image below. Click the “Show your connection credentials” link.

Copy the text shown in the grey box – e.g. “lndhub://…@”

You will need these connection credentials later.

Configure Your Bleskomat ATM

In order for your Bleskomat ATM to create QR codes that the Bleskomat Platform will accept, you must configure it using the Hardware Configuration tool in your Platform account. This requires a USB cable and a web browser with Web Serial support – e.g. Chrome, Chromium, Brave, and Edge.

  1. Connect your Bleskomat ATM to your computer via USB cable
  2. Open the “Hardware Configuration” page in your Bleskomat Platform account
  3. Click the “Connect” button

The tool should automatically connect to your Bleskomat ATM. Then it will check if the device has the latest firmware installed. If not, it will ask you if you would like to update it. After firmware is updated, a few automatic checks are performed before the hardware configuration options are presented.

Once the Hardware Configuration tool is finished, you can move on to the next step.

Fund your wallet

The final step is to fund your wallet.

If you are using the GetAlby browser extension, click the “Receive” button to create an invoice then pay it.

Otherwise, if using BlueWallet, open the app then open the wallet that is connected to your GetAlby wallet account. Click the “Receive” button in that wallet, enter the amount of sats you would like to fund your wallet, and then tap “Create Invoice”. You can now copy the invoice information and send sats via any other Lightning wallet.

Once the Lightning invoice has been paid, you can try a test payment using your Bleskomat ATM.

Test the setup

Now let’s test the whole setup to make sure it’s working as expected.

  1. Insert a coin or bill into the Bleskomat ATM
  2. Push the button
  3. Open a compatible mobile wallet app
    • Please see apps for a list of wallet apps which are compatible
  4. Scan the QR code with the mobile wallet app
  5. Follow the instructions in the mobile wallet app to complete the Lightning payment

You should see a new outgoing transaction appear in your GetAlby wallet. Congratulations, your Bleskomat ATM is now connected and ready to sell sats!
