RIC to REX Token Transition

This is a proposal to convert the Ricochet (RIC) SuperToken to a regular ERC20 token called REX Protocol Token (REX). A new ERC20 contract using OpenZepplin’s ERC20 contract with a custom function for burning RIC tokens for REX tokens one for one (1:1). Moving from a SuperToken to a standard ERC20 token removes a significant amount of attack surface from the protocol. REX is more secure since it removes the SuperToken logic and the upgradability from the RIC token.

Proposed REX Protocol Token (REX) Contract

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract REXProtocolToken is ERC20 {

    ERC20 public constant RICOCHET_TOKEN = ERC20(0x263026E7e53DBFDce5ae55Ade22493f828922965);

    constructor() ERC20("REX Protocol Token", "REX") {
        
    }

    function supportREX(uint amount) external {
        // Burn the SuperToken
        require(RICOCHET_TOKEN.transfer(address(0), amount), "burn failed");

        // Mint the new REX token to 1:1
        _mint(msg.sender, amount);
    }

}

Since RIC has a max supply of 10M, REX will also have a max supply of 10M too.
