Understanding Air-gapped Wallets and How They Enhance Cryptocurrency Security

Cryptocurrency has been on the rise for years and there’s no sign of it slowing down anytime soon. In 2024, more people are embracing crypto’s flexibility, faster transfers, and greater decentralization. At the same time, top financial conglomerates hope to soon launch spot Bitcoin exchange-traded funds.

The fact that cryptocurrency has less vulnerability to inflation than the US dollar is another major factor driving its popularity. Even outside of the United States, people are catching onto the fact that access to other forms of currency comes with some attractive benefits. El Salvador, for instance, is the first nation in the world to formally acknowledge Bitcoin as a lawful tender.

Amid the rise of this digital currency, people with crypto need to have protective measures in place, as cybercriminals will not stop trying to illegally acquire assets that belong to others. 

Safeguards like air-gapped wallets go a very long way toward ensuring that cryptocurrency users don’t have their private keys, funds, or sensitive information compromised by bad actors. 

A Closer Look at Air-gapped Wallets

Air-gapped wallets keep the private keys to your assets safe, while your actual currency sits on the blockchain. These tools rely upon micro-SD cards or QR codes to perform transactions. They’re also completely removed from all forms of wireless connection and lack compatibility with USB drives. 

Put simply, air-gapped wallets are made to protect cryptocurrency from being stolen or otherwise compromised. A critical component in all of this is making sure the protected digital currency doesn’t come into contact with devices or networks that could make it vulnerable to hacks or other cyber invasions. 

Air-gapped wallets come in hardware, computer, and smartphone versions. A hardware wallet is a physical device with displays and buttons that help you safely store your cryptocurrency offline, while also managing various functions.

Computer wallets allow for crypto storage on your PC, but it first has to be removed from all wireless connections, including the internet. 

This means a person with an air-gapped computer wallet can’t have their PC connected to Bluetooth, NFC devices, or wifi. Card slots for SDs or USBs are used for PSBT transfers, while moving signed transactions also works via these slots when verifying blockchain. 

An air-gapped smartphone wallet follows many of the same rules as its computer counterpart. This wallet cannot have any connection to the internet, hence requiring a factory reset before you install the software (via a Micro SD card) that permits this device to operate as an air-gapped wallet. 

Five Ways Air-gapped Wallets Enhance Cryptocurrency Security 

As cybercriminals become increasingly more adept and shifty, it’s vital for digital currency users to protect their assets. Barring safety measures like air-gapped wallets, bad online actors will be rewarded with stolen crypto and more emboldened to target this form of currency.  

Protection from cyber threats

With air-gapped wallets, hackers, malware producers, and other criminals don’t have a feasible means of accessing your private keys. As one cannot use cryptocurrency without this secret number, storing your keys in an air-gapped wallet provides automatic protection against the bad guys. 

These criminals rely upon web connections and the internet to steal goods and information. As such, wifi and further networks only open up crypto assets to potential hacking and theft. Keeping your private keys in a place that cybercriminals cannot reach is an essential component of cryptocurrency security. 

Complete control over your cryptocurrency

Ensuring that no one else reaches your cryptocurrency is an essential part of keeping it secure. With air-gapped wallets, you are the one and only person who can use or access the private keys that you place in storage. The same cannot be said for other crypto repositories, such as multi sig wallets or hot wallets. 

Secure offline transactions

Using an air-gapped wallet means all of your transaction signings happen away from the World Wide Web. By keeping these dealings off the internet and wireless networks, phishers, hackers, and others who are up to no good aren’t given a window to attack your assets. 

Heightened individual privacy

The protection of your private information goes a long way as you work to enhance cryptocurrency security. Those who choose to use an air-gapped wallet are relieving themselves from going through the KYC (Know Your Customer) checks which involve disclosing details about your personal identity. 

In the cryptocurrency world, many people have raised questions about the possibility of privacy breaches while undergoing KYC checks. Sparing yourself from this risk simply adds another layer of protection to your private keys.  

Compatibility with long-term storage

Due to the isolated nature of air-gap wallets, these tools are excellent for crypto users wanting to store their assets for a considerable amount of time. Air-gap wallets don’t require any involvement of a third-party custodian and all transactions are confirmed via a PIN or pressing a button. 

With this grade of protection, you can keep your assets safe and sound for investments, a rainy day fund, or other purposes.

Don’t Wait to Protect Your Cryptocurrency

The sooner you set up an air-gapped wallet, the faster you can take your cryptocurrency security to the next level. In recent years, there have been millions in crypto stolen from companies by malicious online actors.

Given the online world’s inherent vulnerabilities to phishing, malware attacks, hacking, and other similar incursions, anyone with cryptocurrency should make storing their assets offline a priority. This provides a critical defense against growing cybersecurity threats. 

Whether you go for a hardware, computer, or smartphone wallet, you can rest easy knowing that your private keys are greatly shielded while your crypto assets remain safely on the blockchain. 

Of all the ways air-gapped wallets facilitate the security of cryptocurrency, the underlying theme is keeping your keys and transactions away from networks that online criminals can access. Many alternatives to air-gapped wallets miss the mark here, therefore leaving untold amounts of cryptocurrency in serious peril. 

Air-gapped wallets’ capacity to keep transaction signings offline (and spare you from having to undergo recurring KYC checks) only guarantees these instruments will remain essential in further safeguarding cryptocurrency.
