Missing Validation mechanism
The current contract is missing a crucial validation mechanism for asset addresses.the validation should ideally be implemented in the functions increaseCollateral, decreaseCollateral, and combineShorts
While it doesn't directly lead to a loss of funds or a critical failure of the contract, it can cause transactions to fail or behave unexpectedly if an invalid address is provided
Manual
To mitigate the identified issue, it is recommended to incorporate a function that validates the asset address prior to executing any operations. This function should confirm that the address is non-zero and a contract is present at the specified address. Here is a simplified example of how this could be implemented:
Subsequently, this function can be utilized within your increaseCollateral
, decreaseCollateral
, and combineShorts
functions as illustrated below:
This implementation will validate the asset address prior to performing any operations, thereby minimizing the risk of fund loss due to incorrect addresses.
