Overview

OpenSea is the most well-known NFT marketplace, supporting Ethereum, Polygon, Solana, and other chains. While competition has intensified from Blur and Tensor, OpenSea remains the most accessible entry point for NFT discovery and casual collecting, with the widest breadth of collections.

Pricing

Free tierFree to browse and discover — takes 2.5% fee on sales
Paid plans2.5% marketplace fee + creator royalties (variable per collection)

✅ When to use

  • Browsing and discovering NFT collections across multiple chains in one place
  • Casual NFT buying — better accessibility and UX than professional trader platforms
  • Selling NFTs with creator royalty enforcement
  • First-time NFT buyers who want a familiar, accessible experience

❌ When NOT to use

  • Professional high-volume NFT trading — Blur offers 0% fees and better pro tools
  • Solana NFTs — Tensor and Magic Eden have dramatically deeper liquidity
  • Real-time floor sweeping or rapid flipping — specialized tools are much better for this

💡 Personal Tips

OpenSea's 2.5% fee adds up fast for active traders — Blur (0% fee plus BLUR token rewards) has taken most of the professional market. But for browsing and discovery, OpenSea's collection pages and trait filtering are still solid. The 'Recently Listed' sort is useful for finding newly minted pieces before bots grab them. For selling, list on both OpenSea and Blur simultaneously to maximize exposure to different buyer audiences.
