Running Node Modules in React Native

How to use packages that depend on Node.js core modules in React Native.

See the [node-libs-react-native][node-libs-react-native] library as a convenience for implementing this method.

ERC20 is the most common Ethereum token standard. It should be noted that it is also the first Ethereum's token standard as well.

It is also important that the original ERC20 proposal is a definition of token interface. EIP20 does not define a reference implementation for this token standard. Here is OpenZeppelin implementation of ERC20 token: https://github.com/OpenZeppelin/zeppelin-solidity/tree/master/contracts/token/ERC20

ERC20 token standard implementation assumes two ways of token transferring: (1) transfer function and (2) approve + transferFrom pattern.
