# Phase 12: Economics & Billing

> **Mission**: Build a comprehensive billing infrastructure to monetize Synor's L2 services (Storage, Hosting, Database, Compute) with real-time metering, pricing oracles, and transparent cost management.

---

## Executive Summary

Phase 12 creates the economic backbone for Synor's service ecosystem:
- **Real-time Metering**: Track resource usage across all L2 services
- **Pricing Oracles**: Dynamic SYNOR/USD price feeds for stable pricing
- **Billing Engine**: Usage-based invoicing and payment processing
- **Cost Calculator**: CLI and API tools for cost estimation
- **Revenue Distribution**: Automatic fee distribution to stakeholders
