OpenSea is one of the most common methods to view your NFTs. You can only view NFTs whose blockchains are supported on OpenSea. Currently, OpenSea supports Ethereum, Polygon, Solana, and Klaytn blockchains. Your wallet is generally one of the best options to view your NFTs. Regardless of which blockchain you use, the wallet that you use to purchase your NFTs should display your current inventory of digital assets.
