OpenSea is a crypto and digital collectibles marketplace. A seller or buyer must register on an NFT marketplace, such as OpenSea, and KYC verification must be completed in order to be successfully registered on the platform. The next critical step is to configure their wallet for a smooth trading experience. Sellers can now mint and list NFTs on the marketplace, and buyers can buy them. NFTs can be purchased at a fixed price or through auctions. As a result, we have seen how an NFT marketplace such as OpenSea operates. You can also use a white-label Opensea Clone to build your own NFT platforms. Contact blockchain developers for additional customizations.
