AirGap

AirGap is a non-custodial cryptocurrency wallet that lets you secure your crypto assets offline. It achieves this by using two apps, called AirGap Vault and AirGap Wallet. The AirGap Vault is responsible for secure secret recovery phrase generation and storage, as well as air-gapped transaction signing through QR codes. The Vault is installed on a dedicated device with no network connection. The AirGap Wallet creates transactions, broadcasts transactions and shows a portfolio overview. The Wallet is installed on your everyday smartphone with network access. The wallet stores public information. The secret recovery phrase is only stored and used in the AirGap Vault.
