ChainDD is a product from the top Chinese company - ChainDD. The wallet is well-designed with a professional interface. There are news sections for people who like to update the events in the industry. It also deliver Markets section which let users update the data on the exchange. However, the biggest flaw about it is that it let users deposit ERC20 tokens but does not let users send to another address. This can be understand with an internal exchange but no. This is the weirdest flaw I have experienced on a wallet.
