Likelihood:
Unused Claimers Address Array (s_claimers) Causes Unnecessary Storage Waste
Root + Impact
Description
-
The contract declares an
address[] private s_claimersarray intended to store addresses of claimers. -
However, the array is never updated (no addresses are ever pushed), rendering it unused and occupying unnecessary storage space.
address[] private s_claimers; // @> declared but never updated or used
Risk
Likelihood:
-
This will always occur as the array is declared but never updated.
-
It does not affect contract logic or user interaction directly.
Impact:
-
Unnecessary storage consumes gas and increases deployment cost.
-
Maintaining unused variables adds code complexity and potential confusion.
Recommended Mitigation
- address[] private s_claimers;
+ // Remove s_claimers if not used
or keep track of claimers:
function claimSnowman(address receiver, ...) external nonReentrant {
+ s_claimers.push(receiver);
...
}
