# DeFi Protocol Integration

> Example of integrating ZKScore with DeFi protocols

## Overview

This example demonstrates how to integrate ZKScore contracts with a DeFi protocol to track user activity, calculate DeFi scores, and reward protocol participation.

## DeFi Integration Example

<CodeGroup>
  ```javascript JavaScript theme={null}
  class DeFiProtocolIntegration {
    constructor(protocolContract, zkScoreContracts) {
      this.protocol = protocolContract;
      this.zkScore = zkScoreContracts;
    }
    
    async trackLiquidityProvision(user, amount) {
      // Update protocol activity
      await this.protocol.provideLiquidity(user, amount);
      
      // Update ZKScore
      await this.zkScore.scoreCalculator.updateCategoryScore(user, 0, amount / 1000);
      
      // Check achievements
      const liquidityAchievements = [100, 101, 102]; // Different tiers
      for (const id of liquidityAchievements) {
        const canClaim = await this.zkScore.achievementRegistry.canClaim(user, id);
        if (canClaim) {
          await this.zkScore.achievementRegistry.claimAchievement(id, '0x');
        }
      }
    }
  }
  ```
</CodeGroup>

## Best Practices

1. **Real-time Updates**: Update scores as activities occur
2. **Achievement Tracking**: Auto-claim eligible achievements
3. **Event Integration**: Sync protocol events with ZKScore
4. **Gas Optimization**: Batch updates when possible
