# NFT Platform Integration

> Integrate ZKScore with NFT marketplaces and platforms

## Overview

Integrate ZKScore into NFT platforms to verify collectors, reward traders, and build community reputation.

## Use Cases

### Verified Collector Badge

Display verified collector status based on ZKScore:

<CodeGroup>
  ```javascript JavaScript theme={null}
  async function isVerifiedCollector(address) {
    const score = await zkScore.getScore(address);
    const breakdown = await zkScore.getScoreBreakdown(address);
    
    return {
      isVerified: breakdown.nft >= 200,
      tier: getTier(breakdown.nft),
      score: breakdown.nft
    };
  }

  function getTier(nftScore) {
    if (nftScore >= 800) return 'Diamond';
    if (nftScore >= 600) return 'Platinum';
    if (nftScore >= 400) return 'Gold';
    if (nftScore >= 200) return 'Silver';
    return 'Bronze';
  }
  ```
</CodeGroup>

### Marketplace Fee Discounts

Reduce fees for high-reputation traders:

<CodeGroup>
  ```javascript JavaScript theme={null}
  async function calculateMarketplaceFee(seller, salePrice) {
    const score = await zkScore.getScore(seller);
    const baseFee = salePrice * 0.025; // 2.5% base fee
    
    if (score.total >= 700) return baseFee * 0.5; // 50% discount
    if (score.total >= 500) return baseFee * 0.75; // 25% discount
    
    return baseFee;
  }
  ```
</CodeGroup>

## Best Practices

1. **Tier System**: Create clear collector tiers
2. **Visual Badges**: Display reputation visually
3. **Fee Incentives**: Reward high-reputation users
4. **Collection Verification**: Verify authentic collectors
5. **Community Building**: Foster trusted communities
