Download the ZBD Earn SDK for Unity below. Each release links to the .unitypackage to import into your project and lists what changed.
Downloads require access. The SDK is hosted in a private GitHub repository, so you need to be granted access before you can download it.If a download link shows “404 — Page not found”, your GitHub account hasn’t been granted access yet. Reach out to your account manager with your GitHub username or the email on your GitHub account, and they’ll add you.

Download: ZBDSDK-v1.1.7.unitypackageNo breaking API changes — upgrading from 1.1.x requires no code changes, and existing signed-in players carry over automatically.

​
Added

  • Creative modals — show remotely configured promotional creatives with a single ShowCreative() call, with no SDK update or app release needed to change a campaign. Supports multi-page carousels with swipe navigation and page dots, portrait and landscape artwork per page (chosen automatically and updated on rotation), popup / fade / slide transitions, optional tap-through into the rewards experience, skinnable next and close buttons, and A/B variants. Images preload at Init into a memory-bounded, mobile-tuned cache.
  • OnWithdrawWithData event — receive a ZBDWithdrawalSuccessData payload when a player completes a withdrawal, including the method, amount and its USD value, destination where available, and per-method identifiers (transactionId, giftCardId, invoiceId). The existing parameterless OnWithdraw event still fires alongside it, so current integrations keep working unchanged.
  • GetGiftCards — fetch the top gift cards available to the player (region-aware), each with its price in sats and how close the player’s balance is to unlocking it, for building “you’re 80% of the way to a $5 card” moments into your own UI.
  • Utils.GetUserId() — replaces GetUserDetailsId().

​
Changed

  • Face ID is no longer required. The SDK no longer injects NSFaceIDUsageDescription into your Info.plist, and no Face ID or LocalAuthentication code ships in your binary — one less App Store privacy declaration to answer for. Biometric-gated withdrawals remain available behind the opt-in ZBD_ENABLE_BIOMETRICS scripting define.
  • GetUserDetailsId() is deprecated in favour of Utils.GetUserId().
  • iOS Fingerprint Pro SDK updated to 2.17.1.

​
Fixed

  • iOS webview layout. Fixed a family of bugs where the rewards UI could leave parts of the game visible or clip its own content, most notably when a game cold-starts in landscape. The webview is now always full-bleed, sized from the window so it’s immune to WKWebView’s automatic safe-area insetting and Unity root-controller swaps. Device safe-area insets are now passed to the web app on both iOS and Android so content clears the notch correctly.
  • The SDK recovers automatically from stale or invalid cached device attestation — one restart instead of a stuck install.
  • Players blocked by an ad blocker, VPN, or private DNS during device verification now see an actionable message instead of a raw system error.
  • Init no longer hangs when a proxy or WAF returns a non-JSON response.
