Context
tend users manage their websites by chatting on WhatsApp. Every user already has WhatsApp open. We want users to invite friends, but we have no referral system yet. Budget for rewards: $10 per successful referral (paid user).
Your Task
Design the referral system end-to-end. When/how do we prompt users to share? What's the reward structure (referrer, referee, or both)? What prevents abuse? What do we track? Include a rough technical spec (database schema, API endpoints) and mockup the key user flows. Use AI to explore edge cases and optimize the loop.
