AirGap provides a two‑device cold storage solution that isolates private keys on an offline smartphone (AirGap Vault) while using a separate everyday phone (AirGap Wallet) for transaction preparation. The system exchanges transaction data via QR codes, eliminating network connections and cable interfaces for secure signing. Users can also stake supported proof‑of‑stake assets and extend blockchain support through the Isolated Modules API.

Problem
Storing private keys on internet-connected devices exposes cryptocurrency assets to online threats such as malware, phishing, and remote attacks. Hardware wallets offer a solution, but can be expensive or cumbersome to use.
Solution
AirGap provides a free, open-source cold wallet solution that secures cryptocurrency by isolating private keys on an offline device. The AirGap Vault application is installed on a dedicated smartphone or tablet that remains completely disconnected from the internet, creating an "air gap" between the private keys and potential online vulnerabilities. Users can then use the AirGap Wallet application on their everyday smartphone to prepare transactions, which are then transferred to the offline device via QR codes for signing. This two-device approach combines the security of a hardware wallet with the usability of a software wallet, without requiring specialized hardware.
Target Audience
AirGap is designed for cryptocurrency users who prioritize security and self-custody of their assets, including both novice and experienced users.
