Mock Oracle Service: Simulated data sources for weather, price feeds, and sports scores
Metadata Generator: ERC-721 compatible JSON metadata with dynamic attributes
FastAPI Backend: REST API serving metadata endpoints
Web Dashboard: Responsive UI for viewing tokens, minting, and triggering oracle updates
Technical Stack
FastAPI + Jinja2 templates
TinyDB for JSON-based database
Comprehensive test suite (36 tests, 100% passing)
