+# Grant Stream Interest Redirection to Burn - Implementation
+
+## Overview
+
+This implementation addresses the requirement to automatically redirect treasury yield to buy back and burn the project's native token. The system creates a "Buy-back and Burn" mechanism funded entirely by the treasury's passive income, rewarding long-term token holders without depleting capital allocated for developer grants.
+
+## Key Features
+
+### 1. **Automatic Yield-to-Burn Conversion**
+- Treasury yield automatically converted to buy-back operations
+- Configurable burn ratios (default: 50% of yield)
+- Dead address management for permanent token removal
+- Slippage tolerance and protection mechanisms
+
+### 2. **Smart Buy-Back Execution**
+- Real-time price discovery and execution
+- Slippage protection with configurable tolerance
+- Gas optimization and cost tracking
+- Automatic execution timing controls
+
+### 3. **Token Supply Tracking**
+- Comprehensive supply metrics and monitoring
+- Burn history and rate calculations
+- Yield generation tracking
+- Real-time circulating supply updates
+
+### 4. **DAO Governance Controls**
+- Admin-only configuration management
+- Burn ratio adjustments (10% - 90% range)
+- Auto-burn enable/disable controls
+- Execution interval and threshold settings
+
