Missing Storage Gap
Summary
The MondrianWallet2 contract does not include a storage gap, which is important for adding new state variables in future upgrades without causing storage issues.
Vulnerability Details
Upgradeable contracts should have a storage gap to prevent storage layout conflicts when new variables are added. The current contract does not have this gap, which could lead to problems in future upgrades.
Impact
Storage Collisions: New state variables in future upgrades could overwrite existing storage slots.
Upgrade Issues: Makes it harder to upgrade the contract safely.
