FFE-01C: Redundant Usage of SafeMath

Type	Severity	Location
Gas Optimization		FundraiserFacet.sol:L34

Description:

The linked SafeMath operations are guaranteed to be performed safely by their surrounding if clauses and general logical constraints.

Example:

Copy
32require(remaining >= amount, "Fundraiser: amount exceeds remaining.");
33IERC20(s.fundraisers[id].token).transferFrom(msg.sender, address(this), amount);
34s.fundraisers[id].remaining = remaining.sub(amount);

Recommendation:

We advise them to be performed without the usage of SafeMath to optimise the code.

Alleviation:

The calculation was correctly updated to a raw subtraction (-) optimizing the codebase.
