OpenSea is an American digital asset platform founded in 2017 by Devin Finzer and Alex Atallah. It facilitates the trading of cryptocurrencies and the buying, selling, and minting of non-fungible tokens (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.
Originally launched as a peer-to-peer platform, OpenSea grew into one of the largest NFT marketplaces, further expanding with its 2025 release of OS2, a rebuilt version of the platform, allowing the trading of cryptocurrencies.
