COE-01C: Variable Mutability Specifiers (Immutable)

Type	Severity	Location
Gas Optimization		CashOracle.sol:L14-L15

Description:

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

Example:

Copy
10IPegToken public cash;
11IBond public bond;
12
13constructor(IPegToken cash_, IBond bond_) {
14  cash = cash_;
15  bond = bond_;
16}

Recommendation:

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

Alleviation (3dd3d7bf0c2693b2f9c23bacedfa420393f7ea84):

Both referenced variables have been set as immutable per our recommendation, greatly optimizing their read-access gas cost.
