An NFT marketplace is a platform where you can buy, sell, and discover NFTs — unique digital items like art, collectibles, music, and more. If NFTs are digital property, marketplaces are the real estate brokers. This guide covers how to navigate them.
Top NFT Marketplaces
- OpenSea: The largest general marketplace. Supports Ethereum, Polygon, Solana, and more. Widest selection.
- Blur: Professional-focused marketplace for Ethereum NFTs. Lower fees, faster trading. Popular with power users.
- Magic Eden: Leading marketplace for Solana NFTs. Also supports Ethereum and Bitcoin Ordinals.
- Rarible: Community-owned marketplace with its own governance token (RARI).
- Foundation: Curated marketplace focused on high-quality digital art.
How to Buy an NFT
- Connect your wallet (MetaMask for Ethereum, Phantom for Solana)
- Browse collections or search for specific NFTs
- Check the floor price (cheapest available in a collection)
- Click “Buy Now” for immediate purchase, or “Make Offer” to bid
- Confirm the transaction in your wallet
- The NFT appears in your wallet and on the marketplace as owned by you
How to Sell an NFT
- Go to your profile on the marketplace
- Select the NFT you want to sell
- Choose “List for Sale”
- Set a fixed price or create an auction
- Approve the transaction (first-time listing requires a one-time approval)
- Wait for a buyer — you’ll be notified when sold
Fees
- Marketplace fee: 0.5-2.5% of sale price (varies by platform)
- Creator royalty: 0-10% goes to the original NFT creator (enforcement varies)
- Gas fees: Ethereum mainnet can be expensive. Solana and L2s are much cheaper.
Safety Tips
- Verify collection authenticity — check for the blue checkmark and correct contract address
- Beware of fake collections that copy popular NFTs
- Never click “claim” links in DMs — these steal your wallet
- Use a separate wallet for NFT trading
- Research before buying — most NFTs lose value
