+# StackChain Layer 2 Rollup
+
+A high-performance Layer 2 rollup solution for the Stacks blockchain that enables scalable transactions with security guarantees.
+
+## Features
+
+- High-throughput transaction processing
+- Secure state commitment system
+- Challenge-response mechanism for dispute resolution
+- User deposits and withdrawals
+- Internal transfer capabilities
+- Operator validation
+- Merkle proof verification
+- Balance tracking
+- Comprehensive access controls
+
+## Architecture
+
+StackChain implements a Layer 2 rollup system with the following components:
+
+- **Operator Management**: Trusted operators who submit state commitments
+- **State Commitments**: Periodic submissions of Layer 2 state
+- **Challenge System**: Mechanism to dispute invalid state transitions
+- **Token Bridge**: Deposit and withdrawal functionality
+- **Internal Transfers**: Efficient in-rollup token movements
+
+## Security Features
+
+- Operator validation and registration
+- Challenge periods for dispute resolution
+- Merkle proof verification for withdrawals
+- Balance tracking and validation
+- Comprehensive access controls
+- Bond requirements for operators and challengers
+
+## Getting Started
+
+### Prerequisites
+
+- Stacks blockchain environment
+- Clarity contract deployment tools
+- STX tokens for testing
+
+### Deployment
+
+1. Deploy the contract to the Stacks blockchain
+2. Register initial operator(s)
+3. Configure challenge parameters
+4. Begin accepting deposits
+
+### Usage
+
+```clarity
+;; Register as an operator (contract owner only)
+(contract-call? .stackchain register-operator)
+
+;; Deposit tokens
+(contract-call? .stackchain deposit u1000 u1)
+
+;; Transfer within rollup
+(contract-call? .stackchain transfer-in-rollup tx-sender 'SP2J6ZY48GV1EZ5V2V5RB9MP66SW86PYKKNRV9EJ7 u100 u1)
+
+;; Withdraw tokens
+(contract-call? .stackchain withdraw u100 u1 0x...)
+```
+
+## Documentation
+
+Detailed documentation is available in the `/docs` directory:
