Who the market serves
A supplier can provide the market's base asset, while a borrower can post supported collateral and borrow that base asset within protocol limits. This can suit users who want a focused market with transparent collateral factors and who are prepared to monitor utilization, rates, price feeds and liquidation conditions.
It is not a fit for undercollateralized personal credit, guaranteed principal or users who assume all deposited collateral earns the same return as the base asset. The behavior of collateral and base balances must be checked separately.
