Missing Implementation of Batch Minting Functionality in RAACNFT.sol
Summary
The contract documentation mentions batch minting capabilities https://docs.raac.io/core/tokens/RAACNFT?id=implementation-details , but the actual implementation doesn't support this feature. Additionally, the currentBatchSize state variable is maintained but never used, which could lead to confusion and potential issues in future implementations.
Vulnerability Details
The contract has a currentBatchSize variable that can get updated by the owner. This should allow a user to mint multiple NFTs at once but instead it's not used anywhere.
Impact
Gas inefficiency due to unused state variable
Misleading documentation that could cause integration issues
Higher transaction costs for users who need to mint multiple NFTs (need to call mint multiple times)
Tools Used
Manual Code Review
Recommendations
Implement the batch minting functionality as documented
Remove the unused batch-related code if batch minting is not intended
