The amount of citadel bought when there is no discount is always zero. If the user doesnβt specify, or specifies zero as the _minCitadelOut, then the user will get no xCitadel and will still have to pay the full price.
If funding.discount is equal to zero, citadelAmount_ will remain at the uninitialized value of zero rather than the correct value of citadelAmountWithoutDiscount
File: src/Funding.sol (lines 202-216)
function getAmountOut(uint256 _assetAmountIn)
public
view
returns (uint256 citadelAmount_)
{
uint256 citadelAmountWithoutDiscount = _assetAmountIn * citadelPriceInAsset;
if (funding.discount > 0) {
citadelAmount_ =
(citadelAmountWithoutDiscount * MAX_BPS) /
(MAX_BPS - funding.discount);
}
citadelAmount_ = citadelAmount_ / assetDecimalsNormalizationValue;
}
Code inspection
Initialize citadelAmount_ to citadelAmountWithoutDiscount
