A cold wallet is a secure offline storage solution for cryptocurrencies and digital assets, designed to protect them from online hacking threats. Unlike hot wallets (connected to the internet), cold wallets store private keys offline on physical devices or mediums, such as hardware wallets, paper wallets, or metal plates.
