We are looking for an expert smart contract developer with specific knowledge in ERC-721A contracts to join our team on a part-time basis. We have endless smart contracts needing completed. We have a test contract that we'd like you to review and if you find the exploit then we will move further in the progress. 1) Are you familiar with ERC-721A contracts? 2) Can you please have a look at this contract and tell me if you can find the flaw? There is a major flaw in it and our previous dev did not notice it so need to ensure we have competent development team as we have endless work. [login to view URL] Thank you.
