OpenSea[SEA]

Multi-chain marketplace for NFTs and tokens

OpenSea is a multi-chain NFT and token marketplace that has shifted from NFT trading toward trading tokens across many chains. The OpenSea Foundation announced the SEA token with half of the supply allocated to the community, including early users and participants in its rewards waves, whose Treasures preserve eligibility. A launch planned for March 30, 2026 was postponed by co-founder Devin Finzer, and no new date has been set. OpenSea is backed by Paradigm, Coatue and a16z.
