Managing digital assets securely is one of the biggest challenges crypto holders face. Traditional hardware wallets offer better security than online solutions, but AirGap introduces a more efficient approach to self-custody through its innovative dual-device architecture.

How AirGap Delivers Superior Security

The core innovation behind AirGap is its two-device strategy. Rather than relying on a single device, this wallet ecosystem separates the signing mechanism from the connected interface. AirGap Vault runs on a dedicated smartphone that operates entirely offline—completely isolated from the internet. This architecture removes the network-based attack vectors that pose risks to conventional solutions, making it significantly harder for hackers to compromise your private keys.

By keeping your private keys on an offline device, AirGap ensures that sensitive cryptographic material never touches the internet. This is the foundation of true cold storage security for serious crypto investors holding substantial assets.

The Dual-Component Ecosystem

AirGap operates as two complementary applications working in tandem. AirGap Vault functions as your secure vault—the offline component where your private keys are stored and transactions are signed. The companion app, AirGap Wallet, runs on a connected smartphone and handles the user-facing operations like viewing balances and initiating transactions.

This separation of concerns means you get the security benefits of air-gapped cold storage while maintaining the convenience of a mobile interface. Your keys remain isolated while you retain full control and visibility over your digital assets.

Why This Matters for Self-Custody

Self-custody puts you in complete control of your cryptographic material, eliminating reliance on third parties. AirGap’s two-device model makes self-custody more practical by combining offline security with operational ease—a balance that traditional single-device solutions struggle to achieve.
