# DeFi Protocol Templates

Production-ready templates for common DeFi protocols including staking, AMMs, governance, and flash loans.

## When to Use This Skill

- Building staking platforms with reward distribution
- Implementing AMM (Automated Market Maker) protocols
- Creating governance token systems
- Integrating flash loan functionality

## Staking Contract
