borrower	address	The address of the borrower
repayAmount	uint256	The amount to repay on behalf of the borrower
vTokenCollateral	contract IVToken	The collateral to seize

---

setTreasuryPercent

function setTreasuryPercent(uint256 newTreasuryPercentMantissa) external

Parameters

Name	Type	Description
newTreasuryPercentMantissa	uint256	New treasury percent (scaled by 10^18).

---

setProtocolShareReserve
