Severity:
Use of Ownable instead of Ownable2Step in `PuppyRaffle` contract
Summary
The PuppyRaffle contract uses the Ownable contract to manage ownership of the contract. However, it would be more secure to use the Ownable2Step contract instead.The Ownable2Step contract improves the security of ownership transfer by requiring the new owner to accept ownership before the transfer is complete. This helps to prevent the owner from accidentally transferring ownership to a malicious address.
