canOpenLoans on the
CollateralERC20 contract to
canOpenLoans variable controls whether new loans can be taken out against renBTC collateral.
The current multi-collateral loan contracts does not impose caps on the max amount that can be borrowed against deposited collateral and therefore the protocol is exposed to the risk of infinite mints in case renBTC becomes vulnerable. Given that the loan contract is not being used (contract currently contains only $3.5m worth of renBTC) disabling new loans makes sense from a risk/return perspective.
