Introduction

The AirGap Vault is a cold storage app that securely holds your private key and signs transactions through QR-codes. The cold storage feature of AirGap Vault makes it as secure as a hardware wallet.

AirGap Vault works alongside:#

  • AirGap Wallet (Mobile, PC, and Web)
  • Blue Wallet
  • Sparrow Wallet
  • MetaMask (available in public beta)

Supported features#

Offline transaction signing#

You can create an unsigned transaction in an online, view-only wallet such as the ones listed above, then AirGap Vault signs the transaction offline without risk of leaking your secret. Communication is done securely over QR codes.

Entropy collection with dice rolls and coin flips#

Most wallets use the random number generator (RNG) on your device to generate the entropy needed to create your seed phrase. This leaves room for RNG attacks, thereby making your wallet vulnerable to hackers. AirGap supports collecting entropy with dice rolls or coin flips to help you generate a secure and verifiable seed phrase.

BIP-39 Passphrase#

BIP-39 passphrase is an advanced security feature that allows you to create a new account by adding a set of words or characters to your 24-word seed phrase. This functionality enables plausible deniability. It helps you create a β€œhidden” wallet without anybody knowing it exists.

Social recovery#

Social recovery is a feature that introduces the concept of guardians. These guardians are a trusted group of people who can help the owner of a wallet recover a lost or forgotten seed phrase.

BIP-85#

BIP-85 offers solutions to the challenge of having way too many seeds or mnemonics and needing to back them all up securely. It defines a way to derive new mnemonics from a master mnemonic. The benefit is that you have one mnemonic that you back-up, and then generate new multiple mnemonics out of it (for different wallets). Without BIP85, you might end up with dozens of different mnemonics that all need to be backed up.
