AirGap Wallet

Self custody made simple and secure. Protect your crypto and store your private keys offline.

AirGap is a crypto wallet system that lets you secure cypto assets with one secret on an offline device. The AirGap Vault application is installed on a dedicated device that has no connection to any network, thus it is air gapped. The AirGap Wallet is installed on your everyday smartphone.


AirGap Wallet has an overview of all accounts with their respective balances and transaction histories. AirGap Wallet never touches your secret data stored in the AirGap Vault. It is responsible for creating and broadcasting transactions. The prepared transaction is sent to the secure Vault over QR codes, where it is securely signed and sent back.

AirGap Wallet 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.



  • Portfolio overview of accounts synced from AirGap Vault
  • Communication with the Vault application over QR codes if installed on a second device or app switching if installed on the same device
  • Create transactions for all supported currencies like Aeternity, Bitcoin, Ethereum, Tezos, Cosmos, Kusama, Polkadot, Groestlcoin etc.
  • Broadcast signed transactions
  • Transaction history for each account
