Company Info

OpenSea is an NFT marketplace started by Devin Finzer and Alex Atallah. It lets people buy, sell, and trade digital collectibles, NFTs, and other blockchain-based assets. The platform works across multiple blockchains like Ethereum, Solana, and Polygon, giving users more flexibility. With the Seaport Protocol, OpenSea runs as a non-custodial platform. This means users stay in full control of their assets and don’t need to depend on any centralized middlemen.

 

Key Features of OpenSea:

 

  • A marketplace supporting digital art, collectibles, music, and gaming assets.
  • Provides minting tools for users to create and list their NFTs.
  • Works with Ethereum, Polygon, and other networks.
  • Offers Flexible sales options for NFTs.
  • Connects with MetaMask, Coinbase, and other wallets
