Cold Wallet

Support offline cold wallet, as secure as hardware wallet and easy to send transactions at the same time.

  • Offline mode and Watch wallet

    Turn your phone network off or into airplane mode to put your wallet into offline mode. Because the mobile wallet is isolated from the network, it is absolutely secure. You can create a corresponding Watch wallet by scanning the QR code with another mobile phone.

    The Watch wallet is used to view the wallet's balance and transaction information in real time. Watch wallet does not contain mnemonics and private keys, only the addresses of the various coins, so even if stolen, there is no risk of losing assets.

Implement cold wallet function in offline mode

The offline wallet's private key is isolated from the network, so it is also a real cold wallet. By the help of the Watch wallet, transactions can be sent securely. The basic process is as follows:

  • 1. Initiating a transaction in the Watch wallet (the address and balance information in the Watch wallet is in the latest state, so it is possible to initiate a valid transaction), and generating an offline signing QR code.

  • 2. Scan the QR code with the offline wallet, perform offline signing on the offline mobile phone, and generate the signed transaction QR code.

  • 3. Scan the signed transaction QR code with the Watch wallet to send it to the network.

  • Offline cold wallet is practical and economy

    Offline cold wallet isolates the network, so it's absolutely secure. When sending a transaction, the signing process takes place on an offline phone, so there is no risk of leaking private keys.

    To make a cold wallet in offline mode, you don't need to buy extra hardware, it's very economy.
