The largest marketplace for crypto collectibles

Founded in November 2017, OpenSea is proud to remain the largest general marketplace for crypto collectibles, with the broadest set of categories (120 and growing), the most items (over 3 million), and the best prices. We’re doing this through a community of passionate users and developers. We partner with game developers to create customizable storefronts for users to automatically buy and sell their crypto collectibles.

A core part of our vision is that open protocols like Ethereum and interoperable standards like ERC721 will enable vibrant new economies where users truly own their digital items. We think open, liquid marketplaces will help power these new economies. As such, we're building tools that allow any developer to build rich, integrated marketplaces for their digital assets.

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

Our Values

• Ship it +
  At OpenSea, our focus is less around fundraising, marketing or selling tokens, and more around connecting with users and building experiences that people love. We move fast, experiment, and occasionally break things.
• Build an ocean, not an aquarium +
  We're strong believers in open protocols. While digital assets have existed since the dawn of the digital age, 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.
• 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.
