An air-gapped wallet is a type of cryptocurrency wallet that is completely isolated from the internet. This separation enhances security by protecting the wallet from online threats such as hacking or malware.Typically, an air-gapped wallet is a hardware device or a paper wallet. For a hardware device, it often comes with a small screen and buttons, allowing users to manage their assets without being connected to the internet. Paper wallets involve printing out the private keys and public addresses, which can be stored securely offline.Transactions with an air-gapped wallet require a special process. Users initiate a transaction on an online device and then transfer that information to the air-gapped wallet using a USB drive or QR code. Once the transaction is signed, the signed transaction is then sent back to the online device for broadcasting to the blockchain.This method significantly reduces the risk of unauthorized access, making air-gapped wallets a popular choice for those looking to store their cryptocurrencies securely for the long term.
