Introduction to cold storage wallets
A cold storage wallet is basically a cryptocurrency wallet that remains offline. This simple feature provides great protection against cyber attacks or any threats to your funds. On the other hand, hot wallets offer convenience through quick transactions and high flexibility, cold wallets prioritize security by isolating your digital assets from potential online vulnerabilities.
For long-term holders, the “HODLers,” these wallets provide unmatched security for assets intended to be kept untouched for years. Institutions and large size traders are also equipped with these. Sometimes even active traders use cold wallets as a backup storage option, in order to secure most of their capital while allocating a small share of it on hot wallets.
The importance of cold storage wallets can’t be underestimated. They facilitate security and investor confidence, helping the ecosystem to grow and attract newcomers.

How cold storage wallets work
Cold storage wallets security
Isolation from the internet is at the core principles of cold wallets. This is the one and only option to make sure your private keys can’t be accessed online. The mechanical aspects of cold wallets may vary based on their type. As an example, hardware wallets are physical devices that store private keys in secure environments. They feature high-end encryption and can only be accessed via PIN codes, making it super difficult to crack. However, paper wallets involve generating a pair of cryptographic keys (public and private) offline and then printing them out or writing them down. This paper must be stored securely, as access to it equals access to the funds. Air-gapped computers, a more expensive and complex option, are machines completely disconnected from any network, used exclusively to generate and store keys, offering the maximum level of security.
Cold storage wallets set up
We highly recommend purchasing your hardware wallet from a trusted brand. Once you have the device, follow the initial setup instructions: install the dedicated application, create a new wallet, and generate your private keys. These keys are backed up using a recovery phrase, which you should store offline.
For setting up a paper wallet, use a trusted offline generator to create your key pair. Print or carefully write down the keys and keep the paper in a secure, private location, like a safe or a safety deposit box.
With air-gapped computers, ensure the machine is entirely disconnected from any networks. Use specialized software to generate your cryptographic keys, storing them exclusively on the device or writing them down separately. Each method has its own steps, but the ultimate goal remains the same: to provide an impregnable fortress for your digital assets, ensuring they remain safe from any potential cyber threats.
Types of cold storage wallets
Paper wallets
What are they?
Paper wallets are the simplest form of cold storage. The process starts with generating a pair of cryptographic keys—both a public key for receiving funds and a private key for accessing them—offline. These keys are printed or written down on a piece of paper, ensuring they remain completely isolated from any online threats. The concept is straightforward: as long as the paper remains secure, so do your cryptocurrencies.
How to create and use?
Creating a paper wallet is an easy process but it requires careful attention to detail for maximum security. First, use a reputable offline generator to create your key pair. This can be done using software that operates without an internet connection, ensuring the keys are never exposed online. Once generated, print the keys and possibly include a QR code for more convenience. Store the paper in a location immune to physical theft, fire, or water damage—think of safes or safety deposit boxes. To use your funds, you would need to scan the QR code or manually input the private key into a hot wallet to make transactions, but remember that moving your cryptocurrency online even temporarily introduces risk.
Hardware Wallets
Brands recommendations
Hardware wallets are physical devices designed to securely store cryptocurrency private keys. Brands like Ledger, Trezor, and KeepKey dominate this market, each offering their own strengths. Ledger wallets, known for their high-end security architecture, support a wide array of cryptocurrencies. Trezor, one of the first hardware wallets, is one of the most easy to use while maintaining a high level of security, making it a favorite among both novices and experts. KeepKey has what we believe to be the best interface without compromising on security, which is ideal for newcomers.

Setup and use
Setting up a hardware wallet has an initial configuration phase to set up security. When booting up the device, it will prompt you to create a new wallet and generate a recovery phrase—a list of 12, 18, or 24 words that act as a backup in case the device is lost or damaged. This phrase should be written down and stored securely offline. The hardware wallet connects to a computer via USB, but no worries, private keys never leave the device. Most transactions can be signed on the device itself, verified via its built-in screen and physical buttons. This setup is here so that even if the connected computer is compromised, the private keys remain secure. To use the wallet, connect it to a computer, open the dedicated application, and follow the prompts to send or receive funds.
Cold wallet apps
Top apps available
Cold wallet apps are the most technologically advanced form of cold storage, offering exceptional security features while still being user-friendly. Apps like AirGap Wallet, Armory, and Mycelium Wallet are popular choices. AirGap Wallet uses a two-device approach: one device remains offline to sign transactions, while the other connects to the internet to broadcast them. Armory, known for its advanced security features, is favored for deep cold storage solutions. Mycelium Wallet also offers advanced security, integrating with hardware wallets for a multi-layer security approach.
Features and usability
Cold wallet apps offer a range of features designed to enhance security and usability. AirGap Wallet, for instance, uses an air-gapped device (one that never connects to the internet) to sign transactions, ensuring private keys remain offline. This setup eliminates the risk of online attacks, providing a high-security environment for your assets. Armory boasts multi-signature support, hierarchical deterministic (HD) wallets, and cold storage functionality, making it ideal for advanced users. Mycelium Wallet offers a similar range of security features but focuses on ease of use and integration with hardware wallets, creating a seamless user experience for those looking to balance security and convenience.
These apps also provide intuitive interfaces designed to make managing cryptocurrencies easier even for less tech-savvy users. They often include additional features like real-time price updates, integrated exchanges, and decentralized apps (dApps) support. By offering both high security and practical usability, these cold wallet apps enable users to manage their digital assets confidently and securely.
Benefits of Cold Storage Wallets
Security advantages
Cold storage wallets provide top-notch security by operating offline, shielding private keys from online threats like hacking and malware.
