Setters - when a loan is repaid

// Fee is 1% APR - so a loan of 1000$ over a year earns 10*multiplier points
let multiplier = self.points_multiplier.read();
// 1strk = .5USDC, hence the following line
if (category_id_from_address(lend_token) == STRK_CATEGORY) { multiplier = multiplier / 2; }
self.total_points.write(self.total_points.read() + 2 * fee * multiplier);
self.user_points.entry(lender).write(self.user_points.entry(lender).read() + fee * multiplier);
self.user_points.entry(borrower).write(self.user_points.entry(borrower).read() + fee * multiplier);
