AirGap Vault - Secure Secrets

Papers AG

About this app

AirGap Vault is a blockchain agnostic crypto vault that turns your mobile phone into a cold wallet.

AirGap Vault does not connect to any network, irrespective of the device used. This system built into the app makes it more secure than an ordinary crypto wallet.

Transactions can be signed seamlessly without the use of cables, thanks to verifiable QR codes. This opens up multiple possibilities for interacting with other solutions.

AirGap Vault is currently used alongside other companion apps like AirGap Wallet, MetaMask, Sparrow Wallet, BlueWallet, Specter, and any other QR code-based wallets. These companion apps serve as watch-only wallets that allow users to view portfolios and initiate transactions while the Vault signs transactions and protect your private keys offline.

Ratings and reviews

Great app overall. Allows you to use an old spare phone as a hardware wallet. The hardware wallet has good compatibility with existing software wallets, such as Sparrow or Meta mask, not just their own wallet. I wish that it would support Monero and greater compatibility with more phones (unfortunately not all phones can run it). Also: BIP-39 Passphrase option is super hidden, even with advanced options turned on: You have to scroll all the way down when selecting what accounts to generate!!!

Instructions pages automatically skip, so I can't even read them. It asks for my pin that i was never prompted to input myself. There is no other way out of this screen unless I turn my screen off and have an app I can access on my lockscreen to access another app, or I have to reset my phone. So essentially, it's literally non-functional.

Please allow for naming addresses & the chain it's associated with. I like that I can create an account and it works on most all EVM chains. But when every address simply displays an ETH label next to a long alphanumeric string, it's difficult to tell what wallet I began using for ETH transactions vs Polygon vs Songbird etc. Also can you implement a simpler solution for creating multiple addresses under a single secret without having to modify the derivation path? A simple + address button?
