NuWallet creates a Venmo moment by replacing a public key with a mobile number in order to send/receive crypto. Our scheme is generalised to allow _any_ cryptocurrency to be used with _any_ identifier

We introduce a NuCypher-based cryptographic scheme that allows users to use their friends' phone number instead of Ethereum public keys to send crypto.
- Convenient and familiar UX: no cognitive burden on users
- User privacy and self-sovereignty: user controls who can know her Ethereum address. User can only receive payments from pre-approved parties, however their number is uncapped.
- Generalised and scalable: can be used across many identifiers and any cryptocurrencies any other identifier, e.g. email ID, Whatsapp ID, Telegram ID, Signal ID, WeChat ID, etc. This scheme can be extended to include any cryptocurrency.

Target client base (lib):
- Wallets and dApp browsers (Trust wallet, Balance, imToken etc)
- Exchanges (Binance, Coinbase, Kraken etc)
- dApps (OpenSea, CryptoKitties, Decentraland etc).

How it works:
- Register
- Select who from your friend you want to be able to interact with your ethereum address
- Send ETH/ERC-20 to your friend using only their mobile phone!
