Inheritable Smart Contract Wallet

Summary

The inactivity timer can be manipulated by the owner through frequent transactions, resetting the 90-day timer indefinitely. This could prevent the inheritance process from triggering if the owner is actively using the contract.

Vulnerability Details

Issue: The owner can reset the inactivity timer by making frequent transactions, circumventing the inheritance process.

Impact

If the inactivity timer is reset too frequently, it may prevent the inheritance process from executing, denying beneficiaries access to assets. This could result in operational issues where beneficiaries are deprived of their rightful inheritance.

Tools Used

Solidity Analysis: Reviewed the logic related to inactivity checks

Recommendations

implement manual confirmation by the owner when resetting the inactivity timer or introduce a grace period where inactivity is allowed but still needs confirmation.

Restrict the number of inactivity resets within a given timeframe.
