AirGap: A Dual-Device Security Model for Crypto Asset Management

When it comes to safeguarding your cryptocurrency holdings, AirGap stands out as an innovative self-custody solution. Unlike traditional hardware wallets that operate on a single device, AirGap implements a distinctive two-device architecture designed to maximize security while maintaining usability.

How the Two-Device Architecture Works

The system consists of two separate applications working in tandem. AirGap Vault functions as your dedicated storage component, installed on a smartphone that remains completely offline—essentially creating an air-gapped environment with zero network connectivity. This architectural choice is deliberate: by keeping your private keys isolated from any internet connection, the platform eliminates the primary attack vectors that compromise conventional storage solutions.

Meanwhile, the AirGap Wallet serves as your operational interface, running on a connected device. This separation means you can sign transactions securely without exposing sensitive data to network risks. The communication between devices happens through QR codes, adding another layer of physical isolation to the process.

Why This Matters for Cold Storage

For users managing substantial cryptocurrency portfolios, cold storage remains the gold standard for asset protection. AirGap addresses a key limitation of traditional cold storage—the friction of use. By providing a companion app ecosystem, it enables you to access and manage your digital assets more conveniently while maintaining the security guarantees of offline key storage.

The private keys never touch a connected device, making AirGap particularly suitable for long-term asset preservation strategies.
