AirGap

AirGap is a non-custodial cryptocurrency wallet that enables users to secure their crypto assets offline. It does this by using two apps, named AirGap Vault and AirGap Wallet. The AirGap Vault is responsible for secure generation and storage of recovery phrases, as well as air-gapped transaction signing through QR codes. The AirGap Wallet creates transactions, broadcasts transactions, and displays a portfolio overview.
