Configuration

Network Switching

To deploy on Mainnet, update src/lib/stacks.ts:

// Change to true for mainnet deployment
export const IS_MAINNET = true;

// Update contract details for mainnet
export const CONTRACT_ADDRESS = "YOUR_MAINNET_CONTRACT_ADDRESS";
export const CONTRACT_OWNER = "YOUR_MAINNET_OWNER_ADDRESS";

Environment Variables

Create a .env.local file for custom configurations:

# Optional: Custom API endpoints
VITE_STACKS_API_URL=https://api.mainnet.stacks.co
VITE_STACKS_EXPLORER_URL=https://explorer.stacks.co

Testing

Automated Testing

# Run unit tests
pnpm test

# Run tests with coverage
pnpm test:coverage

# Run E2E tests (if configured)
pnpm test:e2e
