The AirGap Approach

AirGap can not only be used with a completely offline device but also on your every-day smartphone.

Supported Coins & Tokens

Currently, we support these currencies, but thanks to our protocol design, we will be able to add many more in the future.

Ethereum ERC20


AirGap not only offers transaction support for different protocols and tokens but also comes with more extended features.


With the Exchange support in AirGap Wallet, swaps can be made directly in-App without having to transfer funds to an exchange and then creating an order. Seamlessly exchange Tezos, Ethereum, Bitcoin and æternity ERC20 directly inside AirGap Wallet.

Delegation & Baking

AirGap has with the baker tezosAirGap a validator for the Proof of Stake protocol Tezos. XTZ holders can earn a share of the validation reward by delegating their Tezzies to a baker. Delegating to tezosAirGap can be made directly in AirGap Wallet.

Browser Extension

AirGap’s Browser Extension bridges the Desktop with the AirGap Vault. Offering secure interactions with protocols directly out of the browser and signing transaction within the offline device in AirGap Vault.
