OpenSea is an American online non-fungible token (NFT) marketplace headquartered in New York City. The company was founded by Devin Finzer and Alex Atallah in 2017.
OpenSea offers a marketplace allowing for non-fungible tokens to be sold directly at a fixed price, or through an auction, based on the Ethereum ERC-721 standard and the layer-2 scaling solution for Ethereum Polygon.
In 2021, following a heightened interest in non-fungible tokens, the company’s revenue reached $95 million in February 2021 and $2.75 billion in September of that year. By January 2022, the company had been valued at $13.3 billion and has been considered the dominant non-fungible token marketplace.
