Summary

The AssetToken contract implementation adopts a non-fixed pragma directive.

Vulnerability Details

The practice of using non-fixed pragmas may lead to compromised or malfunctioning contracts.

Impact

The adoption of non-fixed pragmas opens the door to potential inconsistencies and security weaknesses stemming from variations across Solidity compiler releases. There is a tangible risk that these contracts could be deployed using a superseded compiler iteration, or across diverse blockchain environments, potentially embedding flaws that undermine contract integrity.

Tools Used

Manual Review

Recommendations

It is advisable to anchor the Solidity pragma to the specific compiler version verified during contract testing.
