Verify precision loss

[epociask]

Problem

The current code for converting wei to ether in the given acount_balance oracle definition has a potential issue of precision loss since the returned overflow/underflow byte is unchecked. This can lead to inaccurate conversion results and affect the accuracy of the overall calculations.

Solution

To ensure accurate conversion from wei to ether, it is necessary to verify the precision loss in the existing code implementation. This can be addressed by performing thorough testing and validation.
