Wallet Pregeneration

Pre-generated wallets are a strategic feature within Web3Auth, designed to streamline the onboarding process by allowing developers to create wallet addresses for users before their initial login. This feature offers flexibility in how and when you introduce users to wallet functionalities, enhancing the user experience and engagement.

Capabilities of Pre-generated Wallets​

The ability to pre-generate wallets opens up a variety of use cases, making it easier to integrate Web3 features into your application's user journey:

  • Early Wallet Creation: Initiate wallet creation as part of the user invite or onboarding flow, even before the user has logged into your app for the first time.
  • Deferred Login Setup: Delay the setup of wallet access management, such as OAuth login or passkeys, until the user is ready for their first on-chain transaction, simplifying initial engagement.
  • Wallet Prefunding: Reward users with tokens for off-chain activities, allowing them to claim these rewards when they access their pre-generated wallet.

Utilizing the Pre-generated Wallet API​

Web3Auth provides a straightforward API to facilitate the creation of pre-generated wallets. You can integrate this API into your user signup flow, either after a user verifies their email or independently by supplying their email or unique identifier to the API.

warning

This API only returns the Core Kit Key wallet addresses. To use the wallet addresses with the Web3Auth SDKs, you will need to either use the useCoreKitKey flag in our PnP SDKs or use any of our Core Kit SFA SDKs

Implementation Steps:​

  1. Identify Users: Determine the unique identifier or email for the user within your system. This will be the verifierId used to create the wallet.
  2. API Call: Use the provided API to submit the user's identifier. You'll need to specify parameters from the Web3Auth dashboard, specifically the Verifier Name, Web3Auth Network, and Client Id.
  3. Receive Wallet Address: The API response will include the new wallet address, ready for use by the user upon their first login.
