A cryptocurrency wallet is a software program designed to store public and private keys and interact with blockchain to enable users to send and receive digital currencies and monitor their balances. As cryptocurrencies become more mainstream, choosing a secure wallet is critical to protect one’s assets. A cold wallet provides robust security by ensuring private keys are generated offline and never exposed to a network-connected device. This article discusses what cold wallets are, why one should use them, factors to consider when selecting one, the top options for Android and iOS devices, how to set them up and use them securely, and answers some frequently asked questions.
What is a Cold Wallet?
A cryptocurrency cold wallet, also known as an offline hardware wallet or cold storage device, operates completely offline without ever connecting directly to the internet. Private keys are generated on the device itself via a random number generator and safely stored there. Without an internet connection, cold wallets are isolated from potential attacks by hackers, malware or other unauthorized access attempts targeted at stealing keys and funds. They enable safe, air-gapped storage and usage of cryptocurrencies.
Why Use a Cold Wallet?
- Extremely secure offline storage for private keys
- Protection against online hacking attacks, viruses or malware
- Maintains user control rather than relying on a 3rd party custodial service
- Better long term storage solution compared to only using hot wallets
