EIW-01C: Variable Mutability Specifiers (Immutable)

Type Severity Location
Gas Optimization ExactInputWrapper.sol:L13, L14

Description:

The linked variables are assigned to only once during the contract's constructor.

Example:

ISwapRouter public swapRouter;
IWETH public WETH;

constructor(address _router, address _weth) {
    swapRouter = ISwapRouter(_router);
    WETH = IWETH(_weth);
}

Recommendation:

We advise them to be set as immutable greatly optimizing their read-access gas cost.
