# Asset theft prevention

The fundamental way to prevent asset theft is to protect private keys, mnemonics or DApp permissions. Therefore, you need to protect private keys, mnemonics and other security information and abide by the following principles:

1\. Do not execute QR codes and links of unknown origin at will;

2\. Do not disclose any sensitive information of your own;

3\. Do not take screenshots or photos to save private keys or mnemonics;

4\. Do not use the wallet or export private keys or mnemonics in an unsafe environment.
