Could you build this?
Partial A 1000x1000 collaborative canvas with payments is straightforward in UI and Stripe checkout, but maintaining real-time distributed canvas state, preventing abuse, and handling concurrent pixel claims requires non-trivial real-time backend architecture.
What it would actually take: The stack would combine Next.js, WebSockets or Redis Pub/Sub, and an in-memory or Redis bitmask/array for the million-pixel grid backed by a transactional database (PostgreSQL) for credit accounting and ownership tracking. The hard parts are handling race conditions when thousands of users contest the same pixel, handling high-throughput sub-second canvas sync, and reconciling micro-transactions safely without transaction fee overhead.
