D'CENT Wallet does not store NFTs within the wallet app itself. Instead, it retrieves information about the NFTs you own from the blockchain network in real time and displays them to you. Therefore, there may be cases where NFTs are not displayed due to network errors or errors in the NFT lookup system.
If your NFT assets are not visible due to a network error, you can connect your D'CENT Wallet to a blockchain explorer such as Etherscan / Klaytnscope / Polygonscan / Songbird Explorer, or to an NFT marketplace such as OpenSea to check.
Please refer to the User Guide for how to use OpenSea
