Attestation Set Up

Configure attestation to ensure your app has not been tampered with using required information for Android and iOS.

In order to ensure we have everything we need to detect whether your app has not been tampered with as part of our attestation check, we require a couple of pieces of information.

Here is a handy video guide:

Android

For Android, we need your Bundle ID or package name, i.e.com.domain.appname, which you set in your Unity build settings.

This is NOT the appId ZBD provides you.

We also need the SHA-256 hash of your signing key.

To find your app’s SHA-256 hash key for Google Play:

1. Access Google Play Console

   Sign in to your Google Play Console account.

2. Select your app

   Choose the app for which you need the SHA-256 hash.

3. Navigate to Release

   Go to the Release section in the left-hand menu.

4. Navigate to Setup

   Click on Setup in the submenu.

5. Select App integrity from the options
6. Click on App signing
7. Find the App signing key certificate
8. Select and copy the SHA-256 Fingerprint

During development, you are likely using a custom keystore in Unity, so we will need that SHA-256 hash as well. You can generate the SHA-256 hash key for your keystore using the following command:

 keytool -list -v -keystore path/to/your.keystore -alias your_alias -storepass your_keystore_password -keypass your_key_password

It should look something like this : EA:A1:69:AA:2F:FC:6D:16:84:ED:06:11:E0:65:2B:E0:BB:9C:5B:E3:41:96:06:E2:3D:85:8F:2C:22:2A:E9:86

iOS

App Attest

For iOS builds, you must have App Attest enabled on your provisioning profile. The Earn SDK backend uses App Attest to validate the integrity of your game. Without it, attestation checks will fail.

To enable App Attest:

1. Sign in to your Apple Developer account
2. Navigate to Certificates, Identifiers & Profiles
3. Select your App ID under Identifiers
4. Scroll to the App Attest capability and enable it
5. Save your changes and regenerate your provisioning profile

Make sure to regenerate and download your provisioning profile after enabling App Attest, then update it in Xcode.

Bundle ID & Team ID

For iOS we need your Bundle ID i.e.app id, e.g.com.domain.appname and your Team ID. To find your app’s Team ID for Apple Developer:

1. Access Appel Developer Account

   Sign in to your Apple Developer account

2. Click on Membershipt details
3. Select and copy Team ID

This is NOT the appId ZBD provides you.
