If you have sent a coin or token that is not supported by D'CENT Wallet, you will not be able to see the asset until D'CENT supports it. Please note that your asset will not disappear even if you send an unsupported coin, as it still exists on the blockchain.
If you would like D'CENT to support a coin, you can request it through the Coin addition request form. When the coin is supported according to the company's development roadmap, it will be announced through the official D'CENT channel.
If the token you sent is on a network that is supported by D'CENT Wallet, you can add the account and see your asset by "Add Custom Token".
