Unikura
Summary
Velvett's Unikura repository contains the Velvett membership NFT and collectible NFT contracts. Holders with a valid membership NFT can participate in the minting/trading of the collectible NFTs. The system is designed to be upgradable and integrated with OpenSea. The contracts use the ERC1155 and ERC721 standards to achieve the design goal. Quantstamp conducted the audit with three auditors working independently (and later syncing on their findings) on a best-effort basis. The audit shows that the project is generally well structured and designed. However, the team identified issues of various levels of severity, including medium-severity issues that break the system functionality. In addition, this report provides several best practice recommendations and raises concerns regarding issues in the documentation. During the review period, the Unikura team successfully resolved the majority of identified issues, adhering to best practices. Outstanding concerns related to the centralized system design have been acknowledged. In summary, the smart contracts within the scope of this audit do not present any additional security risks.
