Wallet Pregeneration

Pregenerated Wallets simplify user onboarding by creating wallets for your users before they log in. This approach enables a smoother Web3 experience, giving developers flexibility in introducing wallet functionalities to users at the right time.

Why Use Pregenerated Wallets?​

  • Seamless Onboarding: Create wallets as part of the invite or signup process, so users can jump into your app without additional steps.
  • Deferred Wallet Setup: Delay login setups (e.g., OAuth or passkeys) until users are ready for their first on-chain transaction.
  • Pre-Funding Capability: Send tokens or rewards to wallets before users claim them, perfect for airdrops, welcome bonuses, or preloaded assets.

Use Cases​

  • Early Wallet Creation: Assign wallets to users during onboarding or invitations without requiring immediate login.
  • Preloaded Incentives: Reward users with tokens, NFTs, or other assets for off-chain activities, redeemable when they access their wallets.
  • Enhanced Gaming & App Experiences: Preload game items or promotional rewards to create a frictionless user journey.
