Submission Details
Severity:
Constructors can be marked `payable`
Summary
Payable functions cost less gas to execute
Vulnerability Details
Since the compiler does not have to add extra checks to ensure that a payment wasn't provided, payable functions cost less gas. A constructor can safely be marked as payable, since only the deployer would be able to pass funds, and the project itself would not pass any funds.
