  ## Description
  -AirGap Vault is responsible for secure key generation. Entropy from audio, video, touch and accelerometer are used together with the output of the hardware random number generator. The generated secret is saved in the secure enclave of the device, only accessible by biometric authentication. Accounts for multiple protcols can be created. Transactions are prepared by the AirGap Wallet and then transferred to the offline device via QR code. AirGap Vault is a hybrid application (using the same codebase for Android and iOS). Created using AirGap's protocol agnostic `airgap-coin-lib` library to interact with different protocols and our own secure storage implementation.
