Aave DIVA Wrapper

Summary

The IAaveDIVAWrapper interface defines batch functions like batchRegisterCollateralToken, batchCreateContingentPool, batchAddLiquidity, and batchRemoveLiquidity. However, these functions are missing in AaveDIVAWrapperCore, leading to inefficiencies and potential interoperability issues.

Vulnerability Details

Batch functions in Solidity execute multiple operations in a single transaction, improving efficiency and reducing gas costs. Their absence in AaveDIVAWrapperCore forces users to make multiple transactions, increasing costs and reducing usability.

Impact

• Higher Gas Costs: Users must execute multiple transactions instead of a single batch operation.

• Reduced Usability: Protocols relying on batch processing face inefficiencies.

• Interface Mismatch: External contracts expecting these functions may encounter issues.

Tools Used

• Manual Review

Recommendations

• Implement Missing Batch Functions in AaveDIVAWrapperCore.

• Ensure Full Interface Compliance with IAaveDIVAWrapper.

• Optimize Gas Efficiency by enabling batch processing.

Implementing these changes will enhance usability, reduce gas costs, and maintain standardization.
