✅ Best Practices

  • •Descriptive names: Include collection + number
  • •Clear descriptions: 1-2 sentences max
  • •Consistent traits: Same trait_type across collection
  • •IPFS links: Use ipfs:// for decentralization

📌 Next Steps

  1. 1.Upload image to IPFS using Pinata or NFT.Storage
  2. 2.Update image field with IPFS hash
  3. 3.Upload metadata JSON to IPFS
  4. 4.Use metadata IPFS hash as tokenURI in contract

💡 Key Insight

Well-structured metadata is the difference between a successful NFT collection and one that languishes. Marketplaces rely on consistent trait_type names for filtering, clear descriptions for discovery, and proper image URLs for display. Test your metadata on OpenSea testnets before mainnet launch to catch issues early.
