OpenSea is the first and largest marketplace for user-owned digital goods, which include collectibles, gaming items, domain names, digital art, and other assets backed by a blockchain.

At OpenSea, we're excited about a brand new type of digital good often referred to as a non-fungible token, or NFT. NFTs have exciting new properties: they’re unique, provably scarce, liquid, and usable across multiple applications. Just like physical goods, you can do whatever you want with them! You could throw them in the trash, gift them to a friend across the world, or go sell them on an open marketplace. But unlike physical goods, they're armed with all the programmability of digital assets.

A core part of our vision is that open protocols like Ethereum and interoperable standards like ERC721 and ERC1155 will enable vibrant new economies where users truly own this powerful brand new type of digital item. Because we think open, liquid marketplaces will help power these new economies, we're building tools that allow any developer to build rich, integrated marketplaces for their digital assets. And we're doing this with the help of a community of passionate users, developers, and creators.

We are a team with backgrounds from Stanford, UC Berkeley, Palantir, Google, Facebook, and Pinterest, funded by YCombinator, Founders Fund, Coinbase Ventures, 1Confirmation, Blockstack, and Blockchain Capital.

At OpenSea, our focus is connecting with users and building experiences that people love. We move fast, experiment, and push the envelope.
Build an ocean, not an aquarium +
We're strong believers in open protocols. While digital assets have existed since the dawn of the internet, we strongly believe that what's unique about blockchain-based assets is their ability to exist across multiple interwoven ecosystems. OpenSea prides itself in its open-ness: our platform is open to anyone building user-owned digital assets, and we build on well-adopted open standards, such as ERC721 and ERC1155.
Be a good seatizen +
The web of value allows powerful incentives to be baked into platforms -- with clear rules around how these incentives can adapt over time. We strive to build symbiotic relationships with our partners that mitigate traditional risks of building on third party platforms.
