Summary

The StETHMock contract lacks events for significant state changes such as minting shares, transferring shares, or updating totalPooledEther. Events are crucial for off-chain monitoring and integration, providing transparency over contract operations

Impact

The lack of event emissions for significant state changes such as minting shares and updating totalPooledEther means that external applications or services would not be able to efficiently track these changes. This could hinder the ability of dApps to update their user interfaces in response to contract activities or for users to verify actions through blockchain explorers.
