Our verdict on OpenBiSea
4.0/10OpenBiSea may suit NFT buyers, sellers, and auction participants who want a marketplace described as supporting several networks and web and mobile access. Its most clearly defined offering is NFT trading and auctions. The main caveats are that fees and auction terms are not published in the product details, no audits are listed, and the separate DEX offering is poorly explained. Check the transaction terms and asset details carefully before committing funds.
