The current implementation uses expect() for the address conversion, which will cause a panic if the conversion fails, which naturally is a worse option than better error handling; in rust projects, panicking in some cases leads to the halt of a chain.
Consider replacing the expect() call with proper error handling:
A new error variant within an Error enum:
Then update the call_contract function signature to propagate this new error:
Alternatively, consider adding input validation for the sender address before attempting conversion:
