        self.balances = {}
        self.balances[msg.sender] = total_supply
    
    def transfer(self, to: address, amount: int) -> bool:
        require(self.balances[msg.sender] >= amount, "Insufficient balance")
        self.balances[msg.sender] -= amount
        self.balances[to] += amount
        return True
    
    def balance_of(self, account: address) -> int:
        return self.balances.get(account, 0)

🧪 Testing

Compilation Testing

# Test Python to Solidity compilation
npm run test:compile:solidity

# Test Python to Stylus/Rust compilation  
npm run test:compile:stylus

# Test compilation accuracy and gas optimization
npm run test:optimization

Integration Testing

cd backend
npm test              # Run API endpoint tests
npm run test:compile  # Test compilation engines
npm run test:deploy   # Test deployment pipeline

Contract Validation

# Validate generated Solidity contracts
npm run validate:solidity

# Test Stylus WASM output
npm run validate:stylus

# Gas comparison tests
npm run test:gas-comparison

Manual Testing Workflow

1. Write Python Contract: Create test contract in playground
2. Compile Both Targets: Test Solidity and Stylus compilation
3. Deploy to Testnet: Deploy compiled contract to Arbitrum Sepolia
4. Verify Source Code: Ensure verification works on Arbiscan
5. Gas Analysis: Compare gas usage between Solidity and Stylus
6. Interaction Testing: Test all contract functions work correctly

🔒 Security

Audit Status

• ✅ OpenZeppelin standard contracts
• ✅ ReentrancyGuard implementation
• ✅ Access control mechanisms
• ⚠️ Note: This is a testnet deployment. Full security audit recommended before mainnet

Compilation Security

• Python AST Analysis: Secure parsing and validation of Python code
• Safe Transpilation: Prevents injection attacks during code conversion
• Gas Limit Validation: Automatic checks for gas optimization
• Input Sanitization: All user code is sanitized before compilation
• Solidity Best Practices: Generated code follows OpenZeppelin patterns

Smart Contract Security

• Automated Security Checks: AI-powered vulnerability detection
• Reentrancy Protection: Automatic reentrancy guards in generated code
• Integer Overflow Protection: Safe math operations by default
• Access Control: Proper permission patterns in generated contracts
• Emergency Patterns: Pause functionality and emergency withdrawals

Best Practices for ArbitPy

• Test Both Targets: Always test both Solidity and Stylus outputs
• Gas Optimization: Use Stylus for gas-critical operations
• Code Review: Use built-in AI assistant for security reviews
• Gradual Deployment: Test on Sepolia before mainnet
• Monitor Contracts: Use blockchain explorers for deployed contracts
