Lost wallets generally have the following three conditions. Please be careful
a.When you delete your wallet, there is no backup wallet.
In view of this situation, it is recommended that the user immediately backs up the wallet after the creation of the wallet, adopting dual backup and multiple backup strategies. Double backup refers to Keystore backup and mnemonic backup. Multiple backup refers to verifying that the backup is correct after backing up Keystore and mnemonics. It is verified repeatedly and confirmed without errors.
b.Forgot your Keystore password.
It is recommended that users use a strong password to encrypt the keystore. This password is best generated randomly, and is not commonly used. This can greatly increase the security of Keystore, but it also poses a huge challenge for users to keep their passwords. It is recommended to use chainpassword or other password management tools to properly keep their passwords in case they are forgotten.
c.Lost private key.
The private keys here include mnemonics, keystores, and plaintext private keys. Some users did not verify transcripts when they backed up the mnemonics, or the handwriting was too scribbled to be difficult to identify later, which would make it impossible to retrieve the wallet. Please be careful when backing up your wallet. When you keep your wallet in the future, you should be good at using some secure key management tools to make sure that you can find the private key at any time.
