# Best Practices

> Best practices for building with ZKScore

## Overview

Follow these best practices to build secure, performant, and user-friendly applications with ZKScore.

## Security

1. **Validate Inputs**: Always validate user inputs
2. **Secure API Keys**: Never expose API keys
3. **Rate Limiting**: Implement rate limiting
4. **Error Handling**: Handle all errors gracefully

## Performance

1. **Cache Data**: Cache scores and identities
2. **Batch Operations**: Use batch APIs when possible
3. **Real-time Updates**: Use WebSockets for live data
4. **Optimize Queries**: Query only needed data

## User Experience

1. **Clear Feedback**: Show loading states
2. **Error Messages**: Provide helpful error messages
3. **Progressive Enhancement**: Work without ZKScore
4. **Accessibility**: Ensure accessibility compliance
