How Does an NFT Marketplace Work

To use an NFT marketplace you need a crypto wallet, the type of blockchain you are on will depend on the wallet you connect to the NFT marketplace.

Users or anyone interested in minting NFTs can begin the process by uploading their digital content to the marketplace, this could come in the shape of digital art, videos or anything else the NFT marketplace will support.

Creators define the metadata and attributes associated with the NFT, this includes the name, description, amount created and assigns royalties to the NFT; so every time the NFT is resold the owner receives a percentage of the sale price. 

This ensures the creators will receive compensation for their work.

Creators can choose to list their NFTs at a fixed price, alternatively, you can opt in for an auction-style listing, where the highest bidder wins. This can help to drive the price of the NFT up.

NFTs once purchased by users can be resold or traded on secondary marketplaces, this still maintains a transparency thanks to the blockchain.

NFT marketplaces rely on smart contracts to execute the buying and selling process automatically.

Minting, listing and transferring NFTs requires a transaction fee to cover blockchain network costs, this is usually a small amount. 

NFT marketplaces will provide easy instructions to follow with the set-up of creating an NFT. Most have a user-friendly interface making it easy to use for anyone.

In Conclusion 

NFT marketplaces give artists and creators new ways to monetize their digital art, creating a unique digital ownership experience. 

The transparency of the blockchain gives a clear trail of where the NFT has been and who has held it. 

The most popular NFT marketplace to use is Opensea but many other blockchains have NFT marketplaces.
