Severity:
Use of _mint instead of _safeMint
[M-3] Use of _mint instead of _safeMint
Description: The EggstravaganzaNFT contract uses the _mint function to create new ERC721 tokens, which does not check if the recipient is capable of receiving ERC721 tokens.
Impact:
If tokens are minted to a contract that does not implement the
onERC721Receivedfunction, they could become permanently locked, leading to loss of tokens.The ERC721 standard recommends using
_safeMintto ensure safe transfers to contracts.
Recommended Mitigation: Replace _mint with _safeMint to include safety checks.
