Stripe is connected with all required environment variables. Now let me check Supabase and get the database schema:

I have all the information I need. Here's what I found:

Integration Status:

• ✅ Stripe: Connected with all required environment variables
• ✅ Supabase: Connected but database is empty (0 tables) - we need to create the schema

Now I'll create a structured plan for your internet bandwidth marketplace. Let me set up the todo list:

Now let me start with Task 1: Setup Database Schema & Authentication. I'll create the database tables and authentication system.

Now I have all the Supabase authentication patterns. Let me start building the bandwidth marketplace. I'll create:

1. Database schema with SQL migration scripts
2. Supabase client setup (server & client)
3. Middleware for authentication
4. Authentication pages (login/signup)

I've set up the database schema, authentication system, and landing page. The database includes tables for profiles, bandwidth listings, purchases, and payouts with Row Level Security enabled. The authentication uses Supabase with email/password signup and login pages. Now let me move to the next task.

I've built the seller dashboard with the ability to create, view, and manage bandwidth listings. The dashboard shows key metrics (total bandwidth, total value, active listings) and allows sellers to create new listings with bandwidth amount, price per GB, and description. The status can be toggled between active, paused, and sold out. Now let me move to the buyer marketplace.

I've built the buyer marketplace where users can browse active bandwidth listings, purchase bandwidth with a specified amount, and view their purchase history. The purchase flow calculates the 20% platform fee and 80% seller earnings automatically. Now let me move to integrating Stripe payments and the payout system.

I've integrated Stripe payments with checkout sessions, webhook handling for payment confirmation, and a payout system. When a purchase is completed, a payout record is created for the seller with their 80% earnings. The seller dashboard now shows pending and completed payouts. Let me move to the final task: creating the admin dashboard.

Perfect! I've completed the bandwidth marketplace app with all five major components. The admin dashboard displays comprehensive analytics including total users, sellers, buyers, transactions, revenue, platform fees, seller payouts, and bandwidth sold. It also shows recent transactions in a detailed table. Let me mark all tasks as complete.
