Vulnerability details

Impact

There are variables that do not change so they can be marked as immutable to greatly improve the gast costs. Examples of such variables are: scaler and oracle in ChainlinkOracleWrapper, factory in PoolCommitterDeployer, poolName in LeveragedPool and there are many more.

Recommended Mitigation Steps

Consider applying 'immutable' to reduce gas costs.
