Submission Details
Severity:
`_mint` function is not safe when sending NFTs to contract instead of EOA if the contract doesn't properly handle it, making the NFT stuck in the contract forever
Summary
If the receiver of NFT is a contract and it doesn't implement IERC721Receiver interface, the NFT will be stuck in the contract forever. Use _safeMint instead of _mint to prevent this.
