Severity:
Lack of Token URI Implementation
Summary
The EggstravaganzaNFT contract doesn't implement tokenURI(), breaking compatibility with marketplaces.
Vulnerability Details
The contract inherits from ERC721 but doesn't override:
function tokenURI(uint256 tokenId) public view virtual override returns (string memory)
This causes all NFTs to appear without metadata on platforms like OpenSea.
Impact
Low - Affects display but not functionality.
Tools Used
Manual Review
Recommendations
Implement a proper tokenURI function
Consider using IPFS or on-chain SVG generation
At minimum, document the metadata handling approach
