Setup

Account abstraction provider

To run this example, you will need to set up a project with an Account Abstraction provider. This example uses Zerodev.

See the Zerodev docs to configure your project and environment.

Server-side storage provider

To run this example, you will need to set up server-side storage. This example uses Supabase.

See the Supabase docs to configure your database and credentials.

By default, this example expects a database table called SessionKeyApprovals with two columns:

• privy_did: The Privy user ID for all users who approved session keys. This is the table's primary key
• session_key_approval: The session key approvals associated with each user. This approval grants your server permissioned access to the user's AA account, via a session key that your server has access to.
