Hey everyone, it is Caesar, founder of Banker Smith.

We are building a synthetic USD, called xUSD that offers 1:1 collateralization ratio without any liquidation risks while providing a Web3 native yield. 

We applied a16z CSS, and would love to comnect with founders.

No, sUSD is overcollateralized around 600% but and it is a CDP model, so there is liquidation risk 

However, xUSD is not a CDP model so there is no borrowing, you basically swap it, so 1:1 collateral ratio and there is no liquidation.
