Privy enables you to programmatically create wallets embedded within your application. When you create a wallet, you can specify its owner, which defines who controls the wallet.
  • To create a user wallet, specify a user ID as an owner of the wallet. This ensures only the authenticated user has access to their wallet. All client-side SDKs create user wallets by default and automatically set the wallet owner as the authenticated user.
  • Or, you can specify an authorization key as an owner on a wallet. The holder of the authorization key, typically your application backend, controls the wallet. You must use a server-side SDK to create wallets owned by an authorization key.
The React SDK supports automatically creating embedded wallets for your users when they log in to your app. View this guide to learn more and configure automatic wallet creation.
To create a wallet with the React SDK, use the createWallet method from the useCreateWallet hook:
createWallet: async ({createAdditional?: boolean}) => Promise<Wallet>

​
