💰 Why Bolt

Only with Bolt you get 2.1% + $0.30 on all transactions. That's 10x better than traditional app stores which take 30% of your revenue! That's the fair and transparent pricing you get with using Bolt.

Bolt’s fees are subject to change but will remain highly competitive. For the latest rates, see Bolt Pricing. For details, review the End User Terms and Conditions.

🛠️ Prerequisites

You need 3 things to get started:

1. Existing App: You will need an application in the same platform as this SDK
2. Backend Server: You will need to bring your own backend server (any language)
3. Bolt Merchant Account: Dashboard access to manage your store (sign up or log in)

📦 Installation

Step 1: Install the Unity SDK

Note: For any of these options you can specify a specific version by appending it to the URL with a hashtag, e.g. https://github.com/BoltApp/bolt-unity-sdk.git#v0.0.5 will pin v0.0.5

Option 1: Using manifest.json (Recommended)

1. Open your Unity project
2. Navigate to the Packages folder in your project root
3. Open the manifest.json file in a text editor
4. Add the Bolt SDK dependency to the dependencies section:

{
  "dependencies": {
    "com.bolt.sdk": "https://github.com/BoltApp/bolt-unity-sdk.git#main",
    // ... other dependencies
  }
}

5. Save the file - Unity will automatically download and import the package

Option 2: Using Package Manager UI

1. Open Package Manager in Unity (Window > Package Manager)
2. Click the "+" button in the top-left corner
3. Select "Add package from git URL"
4. Enter the repository URL: https://github.com/BoltApp/bolt-unity-sdk.git#main
5. Click "Add"

If you have any issues our discord support team will be happy to help.

Step 2: Add code to your game

There is sample integrations in the Samples~/ folder.

• BoltBasicExample: will showcase how to initialize the client and check for pending transactions
• BoltDeepLinkExample: will showcase how to handle deep links back into the application.

Step 3: Continue with Backend Integration

You will need to bring your own backend server to complete integration.
