# Asset loss prevention

First of all, asset loss does not mean that the assets are lost in the blockchain, but that the control of the assets is lost (i.e., the security information of the wallet is not kept properly). During the wallet creation process, a mnemonic phrase or private key will be provided to the user for saving, and the saved content will be verified twice. The wallet can only be used after the verification is completed.

Therefore, the most important thing to prevent the loss of assets is to back up the wallet and keep it properly. Here, we recommend using physical/offline storage, which can be saved through multiple channels (must be secure channels), and do not lose or leak your security information. In this way, even if you encounter an abnormality in the wallet, you can continue to use it by importing the private key or mnemonic.
