The ZBD App is a Bitcoin Lightning wallet players can use to receive and manage their rewards. It is one of several Bitcoin cashout options available in the modal alongside Speed Wallet and other Lightning-compatible methods.
The ZBD App handles Bitcoin (Lightning) cashout only. Other payout methods (bank transfer, gift cards, Cash App, Speed Wallet) are handled directly within the in-game modal without requiring a separate app download.

​
What this means for your integration

The ZBD Earn SDK is a white-labeled experience. Your in-game rewards UI — the balance counter, reward notifications, currency name — carries your game’s branding. Players interact with your brand throughout the earning experience. When a player chooses the ZBD App as their Bitcoin cashout method, they are redirected to it to link their gamertag and initiate a withdrawal. After linking, they are returned to your game via a deep link. Players who choose Speed Wallet or another Lightning option follow a similar flow within the modal. As a publisher, you don’t build or maintain any of this flow. Your responsibilities are:
  1. Configure your game’s URL scheme so the ZBD App can redirect players back after account linking.
  2. Surface the cashout entry point clearly in your game UI — tapping it opens the modal where players choose their cashout method.
