ERC20LookthroughUpgradable

ERC20Lookthrough is an ERC-20 whose total supply is tied to a function in an external contract

There is no IERC20LookthroughUpgradable since all functions override IERC20 or are private

Functions

__ERC20Lookthrough_init

  function __ERC20Lookthrough_init(    string name,    string symbol,    address underlyingContractAddress,    string underlyingBalanceFunction  ) internal

The initialization function i.e., a proxy contract's equivalent of a constructor

Parameters:

Name	Type	Description
name	string	Standard ERC-20 name
symbol	string	Standard ERC-20 symbol
underlyingContractAddress	address	The underlying contract
underlyingBalanceFunction	string	The function name of the underlying contract that's called to determine total supply

totalSupply

  function totalSupply(  ) public returns (uint256)

ERC20 totalSupply function that references another contract based on _underlyingContractAddress & arbitrary function _underlyingBalanceFunction

balanceOf

  function balanceOf(  ) public returns (uint256)

ERC-20 balanceOf function that references another contract based on _underlyingContractAddress & arbitrary function _underlyingBalanceFunction
