Inheritable Smart Contract Wallet

Summary

NFTs representing real-world assets can be manipulated by beneficiaries or trustees, leading to unfair valuations, and thereby unfair inheritance distributions. There’s also a risk that beneficiaries might exploit the revaluation process.

Vulnerability Details

Issue: The contract relies on manually entered or potentially manipulated valuations for NFTs, creating an opportunity for exploitation.

Impact

NFT valuation manipulation can result in beneficiaries receiving an unfair share of the estate, leading to disputes and loss of trust in the inheritance process. This can significantly compromise the fairness of the contract’s operations.

Tools Used

NFT Integration: Assessed how NFTs are handled and valued in the contract.

Recommendations

Integrate an oracle or external service to provide accurate valuations for NFTs representing real-world assets.

Allow beneficiaries to appoint a trustee to verify the asset’s valuation periodically.
