The AirGap Approach

AirGap can not only be used with a completely offline device but also on your every-day smartphone.

Offline Device

With AirGap’s two device approach, you can sign transactions completely offline on a device without any network connectivity with the AirGap Vault application and broadcast them with your every-day smartphone with the AirGap Wallet app.

Same Device

Instead of installing AirGap Vault on an offline device, you can also install AirGap Vault and AirGap Wallet on your every-day phone and profit from added security through application sandboxing and app switching for communication.

Supported Coins & Tokens

Currently, we support these currencies, but thanks to our protocol design, we will be able to add many more in the future.
