I would like to work on this issue.

As a smart contract developer proficient in Cairo and Solidity, here's how I can tackle this issue

I will review the current Nameservice contract implementation in Cairo, identifying and fixing any issues with test imports and interfaces.

Re import necessary libraries in the test module, ensuring all required components are accessible.

Update test interfaces to align with the latest contract structure.

Conduct thorough testing to verify Nameservice functionality.

Write additional test cases if needed to ensure comprehensive coverage.
