ImToken is a wallet for phones compatible with Android and iOS. It is possible to store tokens compatible with ETH, BTC, EOS and ERC20, it is centralized, that is, it allows users to access the blockchain without storing it locally. You can manage wallets from multiple chains with a single Mnemonic password. Simply enter a password, save the 12-word password and you are ready. In my point of view it is a portfolio that does not pay much attention to security, as they could implement the
2FA that would provide more security, and still have fees to use the portfolio that are high compared to other existing ones.
