Submission Details
Severity:
[GAS] Redundant totalSupply in EggstravaganzaNFT
Summary:
The contract EggstravaganzaNFT.sol maintains a redundant totalSupply counter.
Vulnerability Details
The contract tracks:
uint256 public totalSupply;
But ERC721 already tracks ownership through _owners mapping, making this duplicate state.
Impact
Low - Gas inefficiency but no security impact.
Tools Used
Manual Review
Recommendations
Remove totalSupply unless explicitly needed
If needed for off-chain queries, consider making it immutable after minting
Use balanceOf or token enumeration if supply info is needed
