如果你 suspect your private key has been leaked, immediate actions should be taken to safeguard your digital assets. First, check your wallet for any unauthorized transactions. If you notice any suspicious activity, you should transfer any remaining assets to a secure wallet immediately. This could involve setting up a new wallet and using a completely new private key.
In the future, be sure to follow best practices for securing your private keys. This includes using hardware wallets, enabling two-factor authentication for any linked accounts, and ensuring backups are securely stored and accessed only by you.
