+# YieldCraft Protocol Aggregator
+
+## Overview
+
+YieldCraft is a smart contract designed to aggregate multiple yield protocols, allowing users to efficiently manage and optimize their asset deposits across different DeFi platforms.
+
+## Features
+
+- Aggregate multiple yield protocols
+- Automatic selection of best-yielding protocol
+- Secure asset management
+- Flexible protocol addition and management
+- Reward calculation and claiming
+- Platform fee mechanism
+
+## Smart Contract Capabilities
+
+### Core Functions
+
+- `deposit-to-best-protocol`: Deposit assets into the highest-yielding protocol
+- `withdraw-from-protocol`: Withdraw assets from a specific protocol
+- `claim-rewards`: Claim accumulated rewards
+- `add-protocol`: Add new protocols to the aggregator
+- `update-protocol-stats`: Update protocol rates and statistics
+
+### Key Components
+
+- Protocol management with active/inactive states
+- User deposit tracking
+- Dynamic APY and TVL calculation
+- Token validation
+- Platform fee calculation
+
+## Error Handling
+
+The contract includes comprehensive error codes for scenarios like:
+- Unauthorized actions
+- Invalid protocols
+- Insufficient balances
+- Slippage limits
+- Protocol activation status
+
+## Configuration Parameters
+
+- Minimum deposit: 1,000,000 smallest token units
+- Maximum slippage: 0.5%
+- Platform fee: 0.1%
+- Maximum protocols: 50
+
+## Security Considerations
+
+- Owner-only protocol management
+- Token and protocol address validation
+- Deposit and withdrawal checks
+- Rewards calculation safeguards
+
+## Deployment Requirements
+
+- Stacks blockchain environment
+- SIP-010 compatible tokens
+- Protocol trait implementation
+
+## Usage Example
+
+1. Add protocols
+2. Deposit assets
+3. Automatically get best yield
+4. Claim rewards
+5. Withdraw assets
+
+## Potential Integrations
+
+- Lending protocols
+- Staking platforms
+- Yield farming strategies
+
+## Limitations
+
+- Limited to 50 protocols
+- Requires ongoing manual protocol stats updates
+
+## Contributing
+
+- Protocol additions
+- Performance optimizations
+- Additional validation logic
