- [ ] Linter passes
- [ ] No TypeScript errors
- [ ] Code review completed
### Security
- [ ] Security audit completed
- [ ] All vulnerabilities addressed
- [ ] Environment variables configured
- [ ] HTTPS enforced
- [ ] Security headers set
### Configuration
- [ ] Environment variables set
- [ ] API keys configured
- [ ] RPC endpoints configured

## Environment Setup
### Production Environment Variables
Create `.env.production`:
```env
# WalletConnect
NEXT_PUBLIC_WC_PROJECT_ID=your_production_project_id
# Error Tracking (Sentry)
NEXT_PUBLIC_SENTRY_DSN=your_sentry_dsn
# Analytics (optional)
NEXT_PUBLIC_ANALYTICS_ID=your_analytics_id
# Feature Flags (optional)
NEXT_PUBLIC_ENABLE_FEATURE_X=true
```
### Build Configuration
Update `next.config.js` for production:
```javascript
module.exports = {
// Production optimizations
compress: true,
poweredByHeader: false,
reactStrictMode: true,
// Security headers
async headers() {
return [
{
source: '/:path*',
headers: [
{
key: 'X-DNS-Prefetch-Control',
value: 'on'
},
{
key: 'Strict-Transport-Security',
value: 'max-age=63072000; includeSubDomains; preload'
},
{
key: 'X-Frame-Options',
value: 'SAMEORIGIN'
},
{
key: 'X-Content-Type-Options',
value: 'nosniff'
},
{
key: 'X-XSS-Protection',
value: '1; mode=block'
},
{
key: 'Referrer-Policy',
value: 'origin-when-cross-origin'
}
]
}
];
}
};
```
## Build Process
### Local Build
```bash
# Build for production
pnpm build
# Test production build locally
pnpm start
```
### Build Verification
```bash
# Check build output
ls -la .next/
# Verify no errors
# Check bundle size
# Test production build
```
## Deployment Options
### Vercel (Recommended)
#### Setup
1. Connect GitHub repository
2. Configure environment variables
3. Set build command: `pnpm build`
4. Set output directory: `.next`
5. Deploy
#### Configuration
`vercel.json`:
```json
{
"buildCommand": "pnpm build",
"outputDirectory": ".next",
"framework": "nextjs",
"regions": ["iad1"]
}
```
#### Environment Variables
Set in Vercel dashboard:
- `NEXT_PUBLIC_WC_PROJECT_ID`
- `NEXT_PUBLIC_SENTRY_DSN`
- Other production variables
### Other Platforms
#### Netlify
```toml
# netlify.toml
[build]
command = "pnpm build"
publish = ".next"
[[redirects]]
from = "/*"
to = "/index.html"
status = 200
```
#### Docker
```dockerfile
FROM node:18-alpine
WORKDIR /app
COPY package.json pnpm-lock.yaml ./
RUN npm install -g pnpm && pnpm install
COPY . .
RUN pnpm build
EXPOSE 3000
CMD ["pnpm", "start"]
```
## Post-Deployment
### Verification
1. **Functionality Check**
- Test wallet connection
- Test transaction creation
- Test multi-sig approval
- Test all features
2. **Performance Check**
- Page load times
- API response times
- Bundle sizes
- Lighthouse score
3. **Security Check**
- HTTPS enforced
- Security headers present
- No console errors
- No sensitive data exposed
### Monitoring Setup
#### Error Tracking (Sentry)
```typescript
// Initialize in app
import * as Sentry from "@sentry/nextjs";
Sentry.init({
dsn: process.env.NEXT_PUBLIC_SENTRY_DSN,
environment: process.env.NODE_ENV,
tracesSampleRate: 1.0,
});
```
#### Analytics
- Set up Google Analytics
- Configure event tracking
- Monitor user behavior
- Track errors
### Monitoring Checklist
- [ ] Error tracking active
- [ ] Performance monitoring active
- [ ] Uptime monitoring configured
- [ ] Alerts configured
- [ ] Dashboard setup
## Rollback Procedure
### Quick Rollback
1. Revert to previous deployment
2. Verify functionality
3. Check error logs
4. Notify team
### Rollback Steps
```bash
# Vercel
vercel rollback
# Or redeploy previous version
git checkout previous-version
pnpm build
# Deploy
```
## Maintenance
### Regular Updates
- **Dependencies:** Weekly
- **Security Patches:** Immediately
- **Feature Updates:** As needed
- **Performance:** Monthly review
### Update Process

2. Run all tests
3. Security audit
4. Deploy to staging
5. Test staging
6. Deploy to production
7. Monitor closely
### Backup Strategy
- **Code:** Git repository
- **Configuration:** Environment variables documented
- **Data:** User data in encrypted storage (client-side)
## Troubleshooting
### Common Issues
#### Build Failures
```bash
# Clear cache
rm -rf .next node_modules
pnpm install
pnpm build
```
#### Runtime Errors
1. Check error logs
2. Verify environment variables
3. Check network connectivity
4. Review recent changes
#### Performance Issues
1. Check bundle size
2. Review network requests
3. Analyze performance metrics
4. Optimize slow operations
## Security Considerations
### Production Security
- **HTTPS:** Always enforced
- **Security Headers:** Configured
- **CSP:** Content Security Policy
- **HSTS:** HTTP Strict Transport Security
- **XSS Protection:** Enabled
### Data Protection
- **Encryption:** All sensitive data encrypted
- **Storage:** Secure storage used
- **Transmission:** HTTPS only
- **Keys:** Session-based keys
## Performance Optimization
### Build Optimizations
- Code splitting
- Tree shaking
- Minification
- Compression
- Image optimization
### Runtime Optimizations
- Caching strategies
- Lazy loading
- Memoization
- Debouncing
- Throttling
## Scaling Considerations
### Horizontal Scaling
- Stateless application
- CDN for static assets
- Load balancing
- Multiple regions
### Vertical Scaling
- Optimize bundle size
- Reduce memory usage
- Optimize database queries (if added)
- Cache aggressively
