Creating Custodial Wallets with Auth0

If your app uses Auth0 for authentication, you can use ZeroDev to seamlessly create a smart wallet for each user. Follow these steps:

1. Visit the Dashboard.
2. Click on the Auth0 / JWT tab in the lower left corner.
3. Enter your Auth0 credentials in the Auth0 Wallet section and click Save.

Currently, integrating with Auth0 involves some manual setup on our side. Upon saving your Auth0 credentials, we will set up the integration within 24 business hours and email you to confirm. If in doubt, you can get in touch with us on Discord or email support@zerodev.app.
