Root + Impact : eventStartDate:BriVault parameter should be made immutable, reducing the gas cost

Description

• eventStartDate::BriVault is a public state variable, but is never updated and is only initialized once in the constructor, hence these kinds of variables should be made immutable which are only initialized once and then never changed.

• This variable is expensive as they are state variables and hence is increasing the gas fee, so it should be made immutable to reduce the gas fee.

Risk

Likelihood: Low

Impact: Low/Gas

Recommended Mitigation

• Add the keyword immutable at the time of declaration as the variable is only initialized once.
