Introduction to OpenSea
Founded in 2017, OpenSea has emerged as the premier decentralized marketplace for Non-Fungible Tokens (NFTs), headquartered in New York City. Co-founders Devin Finzer and Alex Atallah drew inspiration from blockchain-based games like CryptoKitties to create a platform where users can buy, sell, and discover unique digital assets through fixed-price listings or auctions.
Key Milestones:
- 2018: Joined Y Combinator’s startup accelerator.
- 2021: Achieved $350 million in monthly trading volume, reaching a $1.5 billion valuation.
- 2022: Acquired Dharma Labs (Ethereum wallet developer) and Gem.xyz (NFT aggregator).
Despite challenges like phishing attacks and insider trading allegations, OpenSea remains a dominant force in the NFT ecosystem, supporting over 150 million assets across multiple blockchains.
How OpenSea Works: A Step-by-Step Breakdown

Users connect crypto wallets (MetaMask, Coinbase Wallet) to manage transactions. OpenSea supports Ethereum, Polygon, and other EVM-compatible chains.
2. Exploring NFTs
Browse categories like:
- Art: Digital paintings, generative art.
- Music: Exclusive tracks and albums.

OpenSea’s "Lazy Minting" allows creators to list NFTs without upfront gas fees—costs transfer to buyers.
5. Fees Structure
