Aisland Wallet

The purpose of this project is to use a Linux Phone as cold wallet Pinephone The transactions are transmitted by QR code between the Cold Wallet and "Watching" wallet like Metamask.

Linux operating system is much more safe of Android and iOS:

• Android Os is built up from 10 gigabyte of source code, basically impossible to audit.
• iOS is closed source, you have to rely on what Apple declares.
• Linux is the most safe os and it can be customised to reduce the attack surface at the minimum.

The Android/iOS Phones can be kept disconnected but it's a software function and trojan could use the network in stealth way. The Pinephone has a super cool hardware switch to disconnect any kind of network.
