Here, we highly recommend the use of physical or offline storage, which can be stored in multiple channels (must be safe channels), and do not lose or disclose your security information. In this way, even if the wallet is abnormal, you can continue to use it by importing the private key or mnemonic.
- Don't execute QR codes and links from unknown sources.
- Don't disclose any sensitive information of yourself.
- Don't take screenshots or take photos to save private keys or mnemonic.
- Don’t use wallets or export private keys and mnemonics in an insecure environment.
