## What is AirGap

AirGap is a self-custodial, open-source crypto wallet system from the Swiss company Papers. It uses two apps: AirGap Vault, which keeps the private keys on an offline smartphone, and AirGap Wallet, an everyday-phone companion that holds no secrets; transactions pass between them by QR code.

## Who holds the keys

| Parameter | Details |
|---|---|
| Key control | Self-custodial: private keys are generated and kept in AirGap Vault, offline; the companion Wallet app does not see any secrets. |
| Recovery | Access is recovered with the recovery phrase created at setup; AirGap does not store copies of it. |
| Seed phrase | Supports BIP39 passphrases, BIP85 child entropy and social recovery. |

## Features and supported networks

| Parameter | Details |
|---|---|
| Platforms | iOS, Android and desktop; can run on two devices or on a single device. |
| Connectivity | One-way communication between Vault and Wallet through QR codes, with no cables. |
| Supported networks | Bitcoin, Ethereum, Cosmos, Polkadot, ICP, Tezos, Coreum, Optimism, Kusama, Aeternity, RSK (rBTC) and Groestlcoin, plus listed tokens such as USDT and USDC. |
| Staking | Staking of Tezos, ICP, Cosmos, Coreum and Polkadot from AirGap Wallet, with one-click delegation. |
| Hardware wallet support | AirGap Vault can act as an offline signer for other wallets, including MetaMask. |
| Secure element | Uses the phone's own secure enclave; the optional AirGap Knox tool locks an Android phone's networking at system level. |

## Security and audits

- All AirGap components are open source; the Vault and Wallet apps are published on GitHub under the MIT licence.
- Compass Security reviewed the then-unreleased AirGap Vault mobile apps in July 2019; the report is published in AirGap's GitHub repository.
- The Compass Security report found no attack that would let an external attacker or another app extract the stored secrets while the operating system's security measures are in place.
- AirGap states that all components have undergone multiple third-party security audits.

## Fees

| Parameter | Details |
|---|---|
| Staking | Validators run by the AirGap team charge commission, e.g. 10% on Tezos; other validators can be chosen. |

## History

| Date | Event |
|---|---|
| July 2019 | Compass Security carried out a security review of the AirGap Vault mobile apps before their release. |
| 28 September 2026 | AirGap Vault version 3.35.0 was released on GitHub. |

## Risks and caveats

- AirGap does not keep a copy of the recovery phrase; losing it while the device is lost means losing access.
- The security of AirGap Vault depends on the phone's own operating system protections, according to its 2019 audit.

## How voting works

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
