Digital assets and blockchain-based currencies have seen rapid growth and adoption over the past few years. As more people acquire and trade these assets, the need for secure storage solutions has also increased. This is where cold wallets come in – they provide offline storage and help protect your assets from online threats. In this article, we will look at some of the top cold wallet options available for Android and iOS devices.
What is a Cold Wallet?
A cold wallet, also known as an offline wallet or hardware wallet, is a type of digital wallet used to store assets offline. Unlike software wallets connected to the internet, cold wallets are not continuously connected to the web. This makes them less susceptible to online hacks, viruses, and unauthorized access.
Cold wallets come in the form of external devices that plug into your phone, tablet or computer via USB. All private keys are stored on the device itself, not on your phone. Transactions are signed offline on the cold wallet before being broadcasted to the network. This air-gapped setup makes cold wallets extremely secure against remote attacks.
Benefits of Cold Wallets
Here are some of the main benefits of using a cold wallet:
- Enhanced security – As private keys are generated and stored offline, there is no risk of remote hacking attacks. Cold wallets are not affected by viruses or malware.
- Better protection against theft – If your phone gets stolen or lost, you won’t lose your assets as the private keys are on the cold wallet device. You can simply replace your phone and reconnect the wallet.
- Convenient backups – Most cold wallets make it easy to back up your wallet and restore it on another device. This protects against damage or device failure.
- Support many assets – Top cold wallets are compatible with hundreds of blockchain-based assets besides the leading ones like Bitcoin and Ethereum.
- Ease of use – Leading cold wallet models are designed to provide an easy user experience for both beginners and experts. The setup is quick and intuitive.
- Control over funds – With a cold wallet, users have complete control over their assets. There is no custody by a third-party like an exchange. You own the private keys.
