AeThex Passport Domain Verification - Setup Guide

Quick Start (5 Minutes)

1. Install Dependencies

# Root dependencies (backend)
npm install

# Frontend dependencies
cd src/frontend && npm install && cd ../..

2. Setup PostgreSQL Database

Option A: Local PostgreSQL

# Install PostgreSQL (Ubuntu/Debian)
sudo apt update
sudo apt install postgresql postgresql-contrib

# Start PostgreSQL
sudo systemctl start postgresql
sudo systemctl enable postgresql

# Create database and user
sudo -u postgres psql

In PostgreSQL shell:

CREATE DATABASE aethex_passport;
CREATE USER aethex_user WITH PASSWORD 'your_password';
GRANT ALL PRIVILEGES ON DATABASE aethex_passport TO aethex_user;
\q

Option B: Docker PostgreSQL

docker run --name aethex-postgres \
  -e POSTGRES_DB=aethex_passport \
  -e POSTGRES_USER=aethex_user \
  -e POSTGRES_PASSWORD=your_password \
  -p 5432:5432 \
  -d postgres:14

3. Configure Environment

# Copy environment template
cp .env.example .env

# Edit configuration
nano .env

Update these values in .env:

DATABASE_URL=postgresql://aethex_user:your_password@localhost:5432/aethex_passport
PORT=3000
JWT_SECRET=your-super-secret-key-change-this
NODE_ENV=development

4. Run Database Migrations

npm run migrate

You should see:

Starting database migrations...
Running migration: 001_domain_verifications.sql
✓ Completed: 001_domain_verifications.sql
✓ All migrations completed successfully

5. Start Development Servers

Open two terminal windows:

Terminal 1 - Backend:

npm run dev

Terminal 2 - Frontend:

cd src/frontend && npm run dev

6. Access the Application

• Frontend: http://localhost:5173
• Backend API: http://localhost:3000
• Health Check: http://localhost:3000/health

Testing Domain Verification

Test with Your Own Domain

1. Request Verification:

   • Go to http://localhost:5173
   • Enter your domain (e.g., dev.aethex.dev)
   • Click "Request Verification"

2. Add DNS Record:

   • Copy the TXT record value shown
   • Go to your DNS provider (Cloudflare, Google Domains, etc.)
   • Add new TXT record:
     • Name: _aethex-verify
     • Type: TXT
     • Value: aethex-verification=... (the copied value)

3. Verify:

   • Wait 5-10 minutes for DNS to propagate
   • Click "Verify Domain" in the app
   • Success! Your domain badge appears

Check DNS Propagation

# Check if DNS record is live
dig _aethex-verify.yourdomain.com TXT +short

# Alternative method
nslookup -type=TXT _aethex-verify.yourdomain.com

Expected output:

"aethex-verification=abc123def456..."

Common Issues & Solutions

Issue: "Connection refused" to database

Solution 1: Check PostgreSQL is running

sudo systemctl status postgresql

Solution 2: Verify connection string in .env

# Test connection manually
psql postgresql://aethex_user:your_password@localhost:5432/aethex_passport

Issue: "Port 3000 already in use"

Solution: Find and kill the process

# Find process using port 3000
lsof -i :3000

# Kill it
kill -9 <PID>

Issue: DNS verification always fails

Checklist:

1. ✓ DNS record added correctly?
2. ✓ Waited 10+ minutes?
3. ✓ Record name is _aethex-verify (not _aethex-verify.yourdomain.com)?
4. ✓ Record value matches exactly (no extra quotes)?

Debug DNS:

# Check what DNS server sees
dig _aethex-verify.yourdomain.com TXT @8.8.8.8

# Flush local DNS cache
sudo systemd-resolve --flush-caches

Environment Variables Reference

Variable	Required	Default	Description
DATABASE_URL	✅ Yes	-	PostgreSQL connection string
PORT	No	3000	Backend server port
NODE_ENV	No	development	Environment mode
JWT_SECRET	✅ Yes	-	Secret for JWT tokens
RPC_ENDPOINT	For .aethex	-	Blockchain RPC URL
FREENAME_REGISTRY_ADDRESS	For .aethex	-	Contract address
FRONTEND_URL	No	http://localhost:5173	CORS origin
RATE_LIMIT_WINDOW_MS	No	900000	Rate limit window (15 min)
RATE_LIMIT_MAX_REQUESTS	No	100	Max requests per window

Production Deployment

1. Build Frontend

cd src/frontend
npm run build
cd ../..

2. Environment Configuration

# Create production .env
cp .env.example .env.production

# Edit with production values
nano .env.production

Set:

NODE_ENV=production
DATABASE_URL=postgresql://user:pass@production-host:5432/aethex_passport
JWT_SECRET=<strong-random-secret>
FRONTEND_URL=https://yourdomain.com

3. Start Production Server

NODE_ENV=production node src/backend/server.js

4. Serve Frontend

Use nginx or serve built files:

# Using serve
npm install -g serve
serve -s src/frontend/dist -l 5173

Or configure nginx:

server {
    listen 80;
    server_name yourdomain.com;
    
    location / {
        root /path/to/src/frontend/dist;
        try_files $uri /index.html;
    }
    
    location /api {
        proxy_pass http://localhost:3000;
    }
}

Database Backup

Manual Backup

# Backup database
pg_dump -U aethex_user aethex_passport > backup_$(date +%Y%m%d).sql

# Restore from backup
psql -U aethex_user aethex_passport < backup_20260109.sql

Automated Daily Backups

Create /etc/cron.daily/aethex-backup:

#!/bin/bash
pg_dump -U aethex_user aethex_passport | gzip > /backups/aethex_$(date +%Y%m%d).sql.gz
find /backups -name "aethex_*.sql.gz" -mtime +30 -delete

Make executable:

chmod +x /etc/cron.daily/aethex-backup

Monitoring

Health Check Endpoint

# Check if server is running
curl http://localhost:3000/health

Response:

{"status":"ok","timestamp":"2026-01-09T12:00:00.000Z"}

Database Connection Test

# Test query
psql -U aethex_user -d aethex_passport -c "SELECT COUNT(*) FROM domain_verifications;"

Log Files

Backend logs to stdout. Capture with:

# Development
npm run dev 2>&1 | tee logs/app.log

# Production (with pm2)
npm install -g pm2
pm2 start src/backend/server.js --name aethex-passport
pm2 logs aethex-passport
