Utility Token Design Framework

Design a utility token framework for my project:

Project Description: ${{PROJECT_DESCRIPTION}}
Platform Type: ${{PLATFORM_TYPE}}
Target Users: ${{TARGET_USERS}}
Revenue Model: ${{REVENUE_MODEL}}

Create a comprehensive utility token design:

1. **Core Utility Functions**
   - Primary use cases within the ecosystem
   - Secondary utility features
   - Governance participation rights
   - Access/membership benefits

2. **Value Accrual Mechanisms**
   - Fee distribution models
   - Buyback and burn mechanics
   - Staking rewards structure
   - Revenue sharing mechanisms

3. **Token Velocity Management**
   - Strategies to reduce velocity
   - Lock-up incentives
   - Staking mechanisms
   - Time-locked benefits

4. **Demand Drivers**
   - Natural demand sources
   - Artificial demand mechanisms
   - Network effect amplifiers
   - Speculation vs utility balance

5. **Supply Mechanics**
   - Inflation/deflation schedule
   - Emission curves
   - Burn mechanisms
   - Supply caps and adjustments

6. **Economic Sustainability**
   - Long-term viability analysis
   - Competitive moat through tokenomics
   - Regulatory considerations

Provide specific implementation recommendations.
