AirGap Vault is a blockchain agnostic crypto vault that turns your mobile phone into a cold wallet. AirGap Vault does not connect to any network, irrespective of the device used. This system built into the app makes it more secure than an ordinary crypto wallet. Transactions can be signed seamlessly without the use of cables, thanks to verifiable QR codes. This opens up multiple possibilities for interacting with other solutions. AirGap Vault is currently used alongside other companion apps like AirGap Wallet, MetaMask, Sparrow Wallet, BlueWallet, Specter, and any other QR code-based wallets. These companion apps serve as watch-only wallets that allow users to view portfolios and initiate transactions while the Vault signs transactions and protect your private keys offline.
