OpenSea is an American online marketplace for non-fungible tokens (NFTs), founded in 2017 by Devin Finzer and Alex Atallah. It facilitates the buying, selling, and minting of NFTs across a range of blockchains. Headquartered in Miami, OpenSea supports fixed-price sales and auctions for digital assets including artwork, music, gaming items, and domain names.

The company has evolved from a peer-to-peer platform into one of the largest NFT marketplaces.
