Gas Optimizations

[code423n4]

wfCashBase.sol

• L37 - it is less expensive to validate variable != 0 than variable > 0.

• L37/40- You can save gas by using a custom error with an if() instead of a require()

wfCashERC4626.sol

• L23 - it is less expensive to validate variable != 0 than variable > 0.

• L220 - if it were unchecked, gas would be saved, since the mathematical operation can never generate overflow or underflow.

• L23/42/245- You can save gas by using a custom error with an if() instead of a require()

wfCashLogic.sol

• L121/225 - it is less expensive to validate variable != 0 than variable > 0.

• L305 - if it were unchecked, gas would be saved, since the mathematical operation can never generate overflow or underflow.

WrappedfCashFactory.sol

• L12 - An extra gas expense is generated when setting a variable with its default value.

• L57/116/129/211/225/316 - You can save gas by using a custom error with an if() instead of a require()

NotionalTradeModule.sol

• L48/519 - An extra gas cost is generated when setting a variable with its default value.

• L238/254/393/605/618 - Gas is saved, if instead of uint i = 0; uint i is used; Also, gas is saved if instead of i++, unchecked{++i;} is used

• L395/607/619 - it is less expensive to validate variable != 0 than variable > 0.

• L545/547/549 - A local variable is created that is only used once, so it could be used directly in the split.

• L610/623 - Gas is saved if instead of i++, ++i is used

• L169/199/227/234/269/280/378/449/485/573 - You can save gas by using a custom error with an if() instead of a require()

ModuleBase.sol

• L125/126/146/147 - A local variable is created that is only used once, so it could be used directly in the division.

• L154 - it is less expensive to validate variable != 0 than variable > 0.

• L197/198/205/212/219/224/234/235- You can save gas by using a custom error with an if() instead of a require()

AddressArrayUtils.sol

• L41/68/129/148/151 - Gas is saved, if instead of uint i = 0; uint i is used; Also, gas is saved if instead of i++, unchecked{++i;} is used

• L66/223 - it is less expensive to validate variable != 0 than variable > 0.

• L70/132 - Gas is saved if instead of i++, ++i is used

ExplicitERC20.sol

• L52 - it is less expensive to validate variable != 0 than variable > 0.

Invoke.sol

• L74/97 - it is less expensive to validate variable != 0 than variable > 0.

Position.sol

• L53/60/97/219 - it is less expensive to validate variable != 0 than variable > 0.
