OpenSea

OpenSea, established in 2017 by Devin Finzer and Alex Atallah, is a decentralized marketplace that facilitates the buying and selling of NFTs. It provides users with the opportunity to purchase, collect, trade, and even gift NFTs within its platform. Additionally, OpenSea offers developers the ability to create in-app economies using OpenSea.js, establish their own marketplaces, and access the OpenSea API for comprehensive data on sales, listings, bids, and transfers. Notably, OpenSea boasts one of the industry’s lowest commission fees for NFT transactions.

Having garnered significant support, OpenSea has successfully raised over $427M in funding. Its most recent Series C funding round secured an impressive $300M from prominent investors such as Coatue and Paradigm.
