POC for Cold Wallet Crypto DApp

We are looking to develop a cold wallet DApp (Decentralised App) that works with NFC tags. Basically the NFC tag would store the data of public and private keys and with an authentication from the app (if Client ID matches with account and NFC tag) with the NFC tag will allow private key to be ready for transaction such as sending and receiving.

As of now we are only looking to do for Bitcoin

DApp will be available on iOS, Android & Web application (for desktop)

Optional features: 2FA physical token

Optional back-up card
