Root + Impact

Description

• Claim validation should use efficient logic to check if a user has already claimed their pizza slice

• The has_claimed_slice() function contains redundant conditional logic that can be simplified for better gas efficiency and code clarity

Risk

Likelihood:

• The redundant logic executes on every claim validation check

• Unnecessary gas consumption occurs in every claim_slice() operation

Impact:

• Increased gas costs for users claiming pizza slices

• Reduced code readability and maintainability

Proof of Concept

The current implementation uses an unnecessary if-else construct to return a boolean value that already exists. Since simple_map::contains_key() returns a boolean, wrapping it in a conditional that returns true or false is redundant and wastes gas on every validation call.

Recommended Mitigation

The optimized version directly returns the boolean result from simple_map::contains_key(). This eliminates unnecessary conditional logic, reduces gas consumption, and improves code clarity. The function behavior remains identical while being more efficient and readable.
