About nft-tools
OpenSea is the world’s first and largest peer-to-peer marketplace for NFTs and onchain assets. Founded in 2017 by Devin Finzer and Alex Atallah, it allows anyone to buy, sell, create (mint), and trade digital collectibles, art, gaming items, memberships, music, and more — without intermediaries.
In 2025 the platform launched OS2, a complete rebuild that transformed OpenSea from a pure NFT marketplace into a full multi-asset “exchange everything” platform. Users can now trade both NFTs and fungible tokens across 19+ blockchains from a single interface, with native cross-chain purchasing and marketplace aggregation.
Key Features
- Multi-chain support — Ethereum, Solana, Polygon, Base, Arbitrum, Optimism, Avalanche, BNB Chain, Ronin, Blast, Abstract, Soneium, and more
- Token trading — Swap any token via integrated liquidity aggregators
- Cross-chain purchasing — Buy NFTs or tokens on one chain using assets from another
- OpenSea Studio — No-code tools to create and launch NFT collections (lazy minting available)
- OpenSea Pro — Advanced aggregator that sources the best prices from 170+ marketplaces
- Voyages rewards — XP-based quest system tied to the upcoming $SEA token
- Mobile app — Full-featured iOS/Android experience
- Creator tools — Lazy minting, royalty settings, collection management
Fees
- Marketplace fee: 0.5% (reduced from the original 2.5% with OS2)
- Swap fees: Eliminated
- Creator royalties: Optional (set by collection creators)
- Gas fees: Paid by the user (very low on L2s and Solana, higher on Ethereum mainnet)
- Minting via Studio: Free (lazy mint)
Supported Assets
NFTs (ERC-721, ERC-1155, Solana NFTs, etc.), fungible tokens (ETH, SOL, USDC, memecoins, etc.), and cross-chain assets.

Our Verdict
It is no longer the cheapest option for high-volume pro traders (Blur still wins there), but it is the most complete and beginner-friendly marketplace available. The combination of massive selection, cross-chain convenience, free minting tools, and upcoming $SEA incentives makes it the strongest all-rounder.
Pros

- Beginner-friendly interface with powerful pro tools
- Non-custodial — you always control your assets
- Cross-chain buying and token trading in one place
- Free lazy minting for creators
- Strong brand recognition and liquidity
Cons
- Fees still higher than pure zero-fee competitors like Blur
- Ethereum mainnet gas can be expensive during congestion
- Past controversies (royalty policy changes, insider trading incident in 2022)
- $SEA token launch delayed
