Overview
OpenSea is the largest NFT marketplace by volume, but its terms of service have become increasingly controversial. Our analysis reveals significant concerns around creator royalty enforcement, broad liability waivers, unilateral terms changes, and limited recourse for disputes. The platform's dominant market position has not translated into creator-friendly policies.
Key Concerns
- Optional Creator Royalties: OpenSea made creator royalties optional, with a minimum of only 0.5%, significantly reducing creator earnings on secondary sales.
- Broad Liability Waivers: Extensive disclaimers absolve OpenSea of responsibility for smart contract bugs, stolen NFTs, and transaction issues.
- Unilateral Terms Changes: OpenSea can modify terms at any time with minimal notice, affecting your existing listings and collections.
- Content Delisting Power: OpenSea has broad discretion to delist NFTs without clear criteria or appeal process.
- Data Collection: Extensive tracking of wallet activity, browsing behavior, and transaction history.
- Mandatory Arbitration: All disputes must go through binding arbitration with class action waivers.
Positive Aspects
- Market Liquidity: Largest marketplace provides the most potential buyers for your NFTs.
- Multi-Chain Support: Supports multiple blockchains including Ethereum, Polygon, and others.
- Low Platform Fee: 2.5% platform fee is competitive with other marketplaces.
