How Does OpenSea Work?
OpenSea functions like a digital eBay for blockchain-based assets. Built on Ethereum and powered by the Wyvern protocol, it enables secure atomic swaps—ensuring that NFT transfers only occur when payment is received. Users interact with the platform through crypto wallets such as MetaMask.
Getting Started: Step-by-Step
- Set Up a Wallet: Create a MetaMask wallet and fund it with ETH.
- Connect to OpenSea: Visit opensea.io and securely link your wallet.
- Browse or List NFTs: Explore collections or mint your own NFT with customizable metadata.
- Engage with OS2 Voyages: Earn XP points by trading or participating in community events to qualify for the $SEA airdrop.
This seamless process lowers the barrier to entry for new users while offering powerful tools for creators and traders alike.
What’s New in OpenSea OS2?
Launched on May 30, 2025, the OS2 upgrade marks a major leap forward for OpenSea’s infrastructure and user experience.
Key Features of OS2
- Multi-Chain Support: Trade NFTs across 19 blockchains, including Ethereum, Polygon, Solana, and emerging networks.
- Faster Transactions: Optimized smart contracts reduce gas fees and improve transaction speed.

- Modular Interface: Customizable dashboards for creators, collectors, and developers.
These enhancements have helped OpenSea reclaim market dominance from rivals like Blur and Magic Eden.
$SEA Token Airdrop: How to Participate
In February 2025, OpenSea announced $SEA—the platform’s native governance token—alongside a multi-phase airdrop campaign. The distribution rewards early adopters, active traders, and community contributors.
