## Revenue Projections

### Conservative Estimates (Year 1)

**Free Users:** 10,000
- Conversion to Premium: 2% = 200 users
- Revenue: 200 × $100 = **$20,000/year**

**Premium Users:** 200
- Conversion to Enterprise: 5% = 10 users
- Revenue: 10 × $500 × 12 = **$60,000/year**

**Marketplace (10% fee):**
- Average domain sale: $250
- 50 sales/year
- Revenue: 50 × $250 × 0.10 = **$1,250/year**

**Total Year 1:** ~$81,000

### Growth Scenario (Year 2-3)

**Premium Growth:** 20%/year
- Year 2: 240 users = $24,000
- Year 3: 288 users = $28,800

**Enterprise Growth:** 30%/year
- Year 2: 13 users = $78,000
- Year 3: 17 users = $102,000

**Total Year 3:** ~$130,000+

---

## Domain Marketplace

### Listing Requirements
- Must own verified domain
- Price range: $10 - $100,000
- 10% platform fee on sales

### How It Works
1. Domain owner lists with price
2. Buyers browse marketplace
3. Payment processed via Stripe
4. NFT transferred on blockchain
5. Seller receives 90% (minus Stripe fees)
6. Platform keeps 10%

### Future Enhancements
- [ ] Auction system
- [ ] Offer/counter-offer
- [ ] Domain appraisal tools
- [ ] Trending domains
- [ ] Domain history/stats
- [ ] Escrow service

---

## Blockchain Integration (Future)

Current implementation logs NFT minting for async processing. Future phases will include:

### NFT Minting
- Automated minting on Polygon
- Freename registry integration
- Gas fee management
- Retry logic for failed mints

### Verification
- Wallet signature verification
- On-chain ownership proof
- Transfer history tracking

### Marketplace Transfers
- Automated NFT transfers
- On-chain transaction recording
- Transfer confirmation

---

## Security Considerations

### Payment Security
- PCI compliance via Stripe
- No card data stored locally
- Webhook signature verification
- HTTPS required in production

### Domain Security
- Unique domain validation
- Ownership verification
- Transfer authentication
- Marketplace fraud prevention

### Access Control
- Feature access based on tier
- Subscription status checks
- Token-based authentication
- Rate limiting on premium endpoints

---

## Support & Troubleshooting

### Common Issues

**"Domain registration failed"**
- Check Stripe test keys are set
- Verify payment method is valid
- Check database constraints

**"Webhook not received"**
- Verify webhook URL is publicly accessible
- Check `STRIPE_WEBHOOK_SECRET` is set
- Use Stripe CLI for local testing

**"Feature not accessible"**
- Check user's `premium_tier` in database
- Verify subscription is active
- Check `feature_limits` table

### Logs to Check
```bash
# Server logs
npm start

# Stripe webhook logs
stripe logs tail

# Database queries
SELECT * FROM premium_subscriptions WHERE status = 'active';
SELECT * FROM payment_transactions ORDER BY created_at DESC LIMIT 10;
```
