What is OpenSea?
OpenSea is a marketplace for buying, selling, and creating NFTs. Founded in 2017, it has become a go-to platform for trading digital assets, including art, collectibles, domain names, music, and more. OpenSea supports multiple blockchain networks, including Ethereum, Polygon, Base, Arbitrum, Avalanche, and Optimism, making it accessible to a wide range of users.
For collectors, OpenSea provides a vast array of NFTs to browse and purchase, with options for both primary sales (minting) and secondary market transactions. Creators can easily mint and list their own NFTs, set optional royalties, and reach a global audience of potential buyers. The platform also offers features like collection offers and the ability to "sweep" collections, allowing users to buy multiple NFTs from a single collection efficiently.
How does OpenSea work?
OpenSea operates on top of its bespoke Seaport protocol, which enables efficient and secure NFT transactions.
Users onboard via email or connect their cryptocurrency wallets (e.g. MetaMask, Rainbow, or Coinbase Wallet) to interact with the platform. Sellers can list their NFTs for a fixed price or auction, while buyers can make offers or purchase directly.
When a sale occurs, Seaport's smart contracts facilitate the transfer of the NFT and payment. OpenSea typically charges a 2.5% fee on secondary sales, with optional creator royalties. For primary sales, OpenSea receives 10% of the sale price.
Notably, OpenSea also offers a range of additional specialized resources for more advanced use cases. These tools include:
- OpenSea Deals: Allows users to propose NFT-for-NFT trades securely on the platform.
- OpenSea Studio: A tool for creators to easily mint and manage their NFT collections, supporting up to 10,000 individual ERC-1155 NFTs per collection.
- OpenSea Pro: An advanced platform for high-volume traders with reduced fees, analytics tools, and bulk purchasing options.
- OpenSea Drops: Creators can launch NFT collections where buyers mint directly, with options for presales and public stages.
