This is an alpha API and subject to change.

This API enables creating a wallet for a user. You have three options for user identification: email address, custom (user id), and phone number.

The option used to create the wallet will impact the ways it can be used.

  • email: user can login to Crossmint to access and manage their NFTs
  • userId: your project MUST implement the interface as these wallets cannot login to Crossmint
  • phoneNumber: coming soon (will function like email)
