Inheritable Smart Contract Wallet

Summary: This smart contract securely manages digital inheritance on Ethereum. It allows a contract owner to assign beneficiaries who can claim funds if the owner becomes inactive for a set period (default: 90 days)

Vulnerability Details:

• Inactivity period is fixed at 90 days (not configurable).

• Equal fund distribution only, no custom shares.

• Owner loses control once inheritance is unlocked.

• Unclaimed funds remain in the contract.

• High gas cost with many beneficiaries.

• Reentrancy protected using nonReentrant.

Impact:

1. Owner control loss: Once inheritance is triggered, the owner can no longer modify the contract or reclaim funds.

2. Delayed fund distribution: Inactivity leads to delayed inheritance, and beneficiaries must wait for 90 days without any manual override.

3. Fixed share distribution: All beneficiaries receive an equal share of the funds, without flexibility for different allocations.

4. High gas fees: If there are many beneficiaries, the gas cost for distribution increases significantly.

Tools Used:

• Solidity: Smart contract programming language.

• OpenZeppelin Contracts: Used for Ownable and ReentrancyGuard to secure and manage the contract's ownership and prevent reentrancy attacks.

• Remix IDE: For developing, testing, and deploying the contract.
