Hi! We are glad to introduce an open sourced QuidWallet app, mobile watch wallet for your Ethereum address which is useful to track your portfolio stored on cold wallet. Portfolio is synchronized in real-time without need to log in transactions manually.
We are actively working on adding new features. Please feel free to make any suggestions here or in our telegram chat ( /QuidWallet )
