What Is an Air-Gapped Bitcoin Wallet?
An air-gapped wallet is a type of hardware wallet that never connects directly to the internet or wireless networks. This helps protect private keys from online attacks, as they are completely isolated from potential threats. The idea behind air-gapped wallets is to take the concept of 'not your keys, not your coins' to the next level by keeping those private keys completely offline.
The Coldcard Exploit
One such hardware wallet maker, Coldcard, recently fell victim to a massive exploit leading to over $114 million in user losses. This incident highlights the importance of offline security measures to protect private keys, even in air-gapped wallets. The exploit demonstrates that air-gapped wallets are not immune to threats, and users must remain vigilant to protect their funds.
Why Air-Gapped Wallets Are Not Enough
While air-gapped wallets offer some of the strongest protection available for self-custody, they're not a foolproof solution. The Coldcard exploit shows that even air-gapped wallets can be vulnerable to threats. This emphasizes the need for robust offline security measures to protect private keys, such as regular backups and secure storage.
