+# Pharmaceutical Supply Chain Tracker
+
+A Soroban smart contract for tracking pharmaceutical supply chain events on the Stellar blockchain, ensuring transparent and tamper-proof logging of drugs from manufacturer to patient while complying with supply chain traceability standards.
+
+## Features
+
+- Role-based access control for supply chain participants
+- Complete supply chain event tracking and verification
+- GS1 standard compliance for pharmaceutical tracking
+- Cold chain monitoring support
+- Batch tracking with detailed event history
+- Integration with industry standards (DSCSA compliance)
+- Comprehensive audit trail
+
+## Contract Structure
+
+```
+src/
+├── lib.rs          # Core contract configuration and data structures
+├── tracker.rs      # Supply chain event tracking implementation
+├── stages.rs       # Supply chain stage management
+└── utils.rs        # Utility functions and validation
+```
+
+## Getting Started
+
+### Prerequisites
+
+1. Install Rust and add WASM target:
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+rustup target add wasm32-unknown-unknown
+```
+
+2. Install Soroban CLI:
+```bash
+cargo install --locked soroban-cli
+# Or via Homebrew
+brew install soroban-cli
+```
+
+### Building
+
+```bash
+# Build the contract
+make build
+
+# Run tests
+make test
+
+# Format code
+make fmt
+
+# Run linter
+make clippy
+
+# Run security audit
+make audit
+```
+
+## Contract Deployment
+
+1. Set up environment variables:
+```bash
+export SOROBAN_RPC_URL="https://your-testnet-url"
+export SOROBAN_NETWORK_PASSPHRASE="Test SDF Network ; September 2015"
+export DEFAULT_ADMIN_SECRET_KEY="your-admin-secret-key"
+```
+
+2. Deploy to testnet:
+```bash
+make deploy-testnet
+```
+
+## Usage
+
+### Contract Initialization
+
+```rust
+// Initialize contract with admin
+PharmaceuticalSupplyChain::initialize(env, admin);
+
+// Assign roles to entities
+PharmaceuticalSupplyChain::assign_role(env, admin, manufacturer, Role::Manufacturer);
+PharmaceuticalSupplyChain::assign_role(env, admin, distributor, Role::Distributor);
+PharmaceuticalSupplyChain::assign_role(env, admin, pharmacy, Role::Pharmacy);
+```
+
+### Supply Chain Events
+
+```rust
+// Create new batch
+PharmaceuticalSupplyChain::create_batch(
+    env,
+    manufacturer,
+    batch_id,
+    location,
+    metadata,
+);
+
+// Ship batch
+PharmaceuticalSupplyChain::ship_batch(
+    env,
+    distributor,
+    batch_id,
+    location,
+    metadata,
+);
+
+// Receive batch
+PharmaceuticalSupplyChain::receive_batch(
+    env,
+    receiver,
+    batch_id,
+    location,
+    metadata,
+);
+```
+
+### Batch Verification
+
+```rust
+// Get batch history
+let history = PharmaceuticalSupplyChain::get_batch_history(env, batch_id);
+
+// Verify batch integrity
+let is_valid = PharmaceuticalSupplyChain::verify_batch(env, batch_id);
+
+// Get current status
+let status = PharmaceuticalSupplyChain::get_batch_status(env, batch_id);
+```
+
+## Data Structures
+
+### Supply Chain Roles
+
+```rust
+pub enum Role {
+    Manufacturer,
+    Distributor,
+    Wholesaler,
+    Pharmacy,
+    Hospital,
+}
+```
+
+### Batch Status
+
+```rust
+pub enum Status {
+    Created,
+    InTransit,
+    Received,
+    Quarantined,
+    Approved,
+    Rejected,
+    Dispensed,
+}
+```
+
+### Event Structure
+
+```rust
+pub struct Event {
+    timestamp: u64,
+    entity: Address,
+    event_type: Symbol,
+    location: String,
+    status: Status,
+    metadata: Vec<String>,
+}
+```
+
+## Testing
+
+The contract includes comprehensive test coverage:
+
+- Unit tests for each component
+- Integration tests for complete supply chain flow
+- Role-based access control tests
+- Event tracking validation
+- Batch verification tests
+
+Run tests with:
+```bash
+make test           # Run all tests
+make test-integration # Run integration tests
+```
+
+## Security Considerations
+
+- Role-based access control for all operations
+- Event immutability and auditability
+- Cryptographic verification of entities
+- Soroban security best practices
+- Regular security audits
+
+## Standards Compliance
+
+- GS1 GTIN implementation for product identification
+- DSCSA compliance features
+- Industry-standard event tracking
+- Cold chain monitoring support
