First Flight #18: T-Swap

Summary

Additional checks can be added to ensure valid input values. For instance, in the _swap function, validate that inputAmount and outputAmount are not only non-zero but also within expected ranges.

Vulnerability Details

Inadequate input validation can lead to unintended behavior, potential exploits, and contract malfunction. Ensuring that input values are within expected ranges helps maintain the integrity and security of the contract. Specifically, in the _swap function, it is important to verify that inputAmount and outputAmount are valid and within acceptable limits before proceeding with the swap operation.
