About

This project is meant to be a stablecoin where users can deposit WETH and WBTC in exchange for a token that will be pegged to the USD. The system is meant to be such that someone could fork this codebase, swap out WETH & WBTC for any basket of assets they like, and the code would work the same.

Known Issues

The following issues can be ignored.

• A known gas issue, is that we use storage variables instead of immutables for storing the addresses of the collateral. You can ignore this.
• If the protocol ever becomes insolvent, there is almost no way to recover. This is a known issue.
• We don't want the constructor marked as payable, as we like the extra protection it gives us from accidentally deploying a contract with ETH.
