The Complete Guide to Air Gapped Crypto Wallets and Their Uses

An air gapped crypto wallet is a physical device that stores your cryptocurrency private keys offline, completely disconnected from the internet. This provides an additional layer of security against hacking and cyber attacks.

Air gapped wallets are designed to be isolated from the internet, which makes them virtually unhackable. They use a combination of physical and digital security measures to protect your funds.

One of the most significant benefits of air gapped wallets is their ability to protect against phishing attacks, which are a common way for hackers to steal cryptocurrency. By keeping your wallet offline, you eliminate the risk of falling victim to phishing scams.

Air gapped wallets are not just for individuals; they're also used by organizations and institutions to store large amounts of cryptocurrency securely.

A cold wallet is essentially the same thing as an air-gapped wallet, and it's a device or system that generates and stores the private keys required to access your cryptocurrencies offline.

It's typically a hardware device or a specialized computer that remains disconnected from the internet, ensuring that your private keys cannot be compromised through online vulnerabilities.

This offline storage method sets cold wallets apart from their hot wallet counterparts, which are connected to the internet and therefore more susceptible to cyber attacks.

Air-gapped wallets, or cold wallets, have scannable QR codes, and some have a tiny micro-SD card for storing transaction history that has occurred on the crypto wallet.

By keeping your private keys offline, these wallets provide a formidable defense mechanism that shields your assets from potential cyber risks.

These wallets are a type of hardware wallet — physical devices — but not all hardware wallets are air-gapped wallets.

Cryptocurrency wallets can be categorized into two main types: custodial and non-custodial wallets. Custodial wallets, like Binance and Kraken, manage your cryptocurrency and store your private key on your behalf, but this means you lack control over your funds.

Non-custodial wallets, on the other hand, grant users control over their private keys, making them responsible for signing and validating transactions. These wallets are typically decentralized and include options like Trust Wallet and Ledger Nano S Plus.

Custodial wallets often have user-friendly designs and recoverable accounts, while non-custodial wallets have simpler interfaces that may require some technical know-how. If you lose your private keys with a non-custodial wallet, there's no way to access your accounts.

There are three subcategories of wallets: software wallets, hardware wallets, and paper wallets. Software wallets are run on computers or mobile devices, hardware wallets are physical devices designed for storing private keys offline, and paper wallets are physical documents containing your private keys.

Air-gapped wallets fall into one of these subsets, and there are three broad categories of air-gapped crypto wallets. These include air-gapped hardware wallets, air-gapped computer wallets, and air-gapped smartphone wallets.

Here's a breakdown of the three types of air-gapped crypto wallets:

To create an air gapped wallet, you'll need a dedicated hardware device such as a hardware wallet or a Raspberry Pi.

A hardware wallet is a great option, but make sure you choose one from a trusted manufacturer to ensure security.

You can also use a separate computer, but be aware that this may compromise the air gapped aspect of your wallet.

A hardware wallet will provide an additional layer of security for your air gapped wallet, keeping your private keys safe from unauthorized access.

When selecting a hardware wallet, ensure it's compatible with your chosen software, which can be obtained from the wallet manufacturer's official website.

The official website is the best place to download the software, as it minimizes the risk of tampering or malware.

Air-gapped crypto wallets operate through computer-based software, connected to the wallet's QR code or micro-SD card. This software uses partially signed transactions, such as Partially Signed Bitcoin Transactions (PSBTs) for Bitcoin and Partially Signed Ethereum Transactions (PSETs) for Ethereum.

To perform a Bitcoin transaction, you create a PSBT using a Bitcoin wallet, then export it to your air-gapped wallet. The transaction is then signed using the private keys of your air-gapped wallet.

The offline signing process is a crucial aspect of air-gapped wallets. By storing private keys in an offline environment, you prevent exposure to online threats.

Here's a step-by-step overview of a typical air-gapped crypto wallet transaction:

The first device remains entirely offline, storing the private keys essential for authorizing transactions. Due to its complete separation from the internet, this device ensures the security of private keys, making it resistant to hacking attempts.

Air-gapped crypto wallets are a game-changer when it comes to security. They're not connected to the internet, making them immune to attacks and reducing the risk of hacking, phishing, malware, and network vulnerabilities.

By keeping your private keys offline, you eliminate the risk of online attacks and hacking attempts, allowing you to carry out cryptocurrency transactions with peace of mind. This added layer of security ensures that your digital assets remain under your control and are shielded from potential threats.

Air-gapped wallets provide an extra level of security by requiring physical access to the device holding the private keys. This means that even if a cybercriminal manages to infiltrate your online systems, they would still need physical access to the offline device to compromise your funds.

Private keys stored exclusively in the air-gapped wallet reduce the risk of theft significantly.

Setting up an air gapped wallet is a straightforward process that involves acquiring the necessary equipment and software, and following the manufacturer's instructions to set up the hardware or computer as an air gapped environment.

To maintain your air gapped wallet, remember to keep your device disconnected from the internet at all times to maintain its security. This is crucial to ensure your wallet remains secure.

You'll need to follow a series of steps to set up your air gapped wallet, including installing the wallet software, generating your private keys, and configuring the wallet settings per your preferences.

The setup process requires technical know-how, which can be a disadvantage for those who may not have that ability.

Having successfully set up your air gapped wallet, you'll have total control of your digital assets, giving you an increased level of autonomy consistent with the cryptocurrencies' decentralized nature.

To maintain and make transactions with your air gapped wallet, you'll need to follow a specific process, which we'll explore further in this article.
