🎯 Key Takeaways & Knowledge Check

You've explored the NFT marketplace landscape—from how listings work to advanced trading features. Let's consolidate what you've learned before testing your knowledge.

🏪 Marketplace Fundamentals

  • •Non-custodial: You own NFT until sale completes. Marketplaces are interfaces, not escrows.
  • •Off-chain orders: Free listings via signature. Buyer pays gas to execute.
  • •Fee wars: 0% (Blur) vs 2.5% (OpenSea). Trade liquidity for cost.

💰 Royalty Reality

  • •EIP-2981: Suggestion, not law. Blur ignores by default.
  • •Operator filter: OpenSea's tool to block non-royalty platforms (controversial).
  • •Trade-off: Enforced royalties reduce liquidity but support creators.

🧹 Advanced Features

  • •Floor sweeping: Buy cheapest NFTs in bulk, save 80% gas.
  • •Trait bidding: Snipe specific trait combos below fair value (Blur only).
  • •Aggregation: Blur indexes OpenSea, LooksRare—shared liquidity.

📊 Strategic Insights

  • •Beginner-friendly: OpenSea (better UI, more liquidity).
  • •Pro traders: Blur (0% fees, advanced tools, aggregation).
  • •Cost analysis: Calculate fees + royalties + gas before listing.

🎓 Core Lesson

NFT marketplaces are in a race to optimize the trade-off triangle: low fees (Blur's 0%), high liquidity (OpenSea's volume), and creator support (enforced royalties). No platform wins all three. Blur sacrificed creator royalties for zero fees and won traders. OpenSea sacrificed low fees for ecosystem stability. LooksRare tried token incentives but couldn't compete on features. As a user, choose based on your priorities—casual collectors pick OpenSea for ease; pro traders pick Blur for efficiency; creator-focused users pick platforms enforcing royalties. The 2023 marketplace wars taught us: fees matter less than liquidity, but liquidity depends on network effects, not just features. OpenSea still has 40%+ share despite higher fees because most NFT buyers don't care about basis points—they care about finding what they want.
